Description

The present invention relates to an appropriation business support method and an appropriation business support device that support the appropriation business.

The work of determining whether or not the semi-finished products held in inventory can be applied to the manufacture of the ordered product and putting the semi-finished products determined to be applicable into the product processing process is called the appropriation work. In this appropriation work, the combination of the semi-finished product and the made-to-order product to be judged whether or not the appropriation is possible often has a many-to-many relationship in high-mix small-lot production such as make-to-order production. That is, a plurality of types of semi-finished products that are in stock at the time of appropriation judgment, and a plurality of types of ordered products or products that are expected to be ordered at the time of the judgment (hereinafter collectively referred to as "ordered products"). Appropriateness is determined for the combination with.

Whether or not a semi-finished product can be applied to the manufacture of a certain ordered product is set in order to satisfy the characteristic values obtained by inspecting the semi-finished product and the required specification values required by the ordered product with sufficient accuracy. Judgment is made based on the relationship with the judgment specification value of the internal standard. The characteristic values of semi-finished products often differ from production lot to production lot. Further, in general, the judgment specification value of the ordered product differs depending on the product type. Therefore, the determination of appropriation is actually performed for each production lot of semi-finished products and for each product type of the ordered product.

The person in charge of appropriation engaged in the appropriation business determines whether or not the appropriation is possible for all combinations of the semi-finished products in stock at the time of determining whether or not the appropriation is possible and the ordered products. Then, the person in charge of appropriation makes each judgment result, the inventory quantity of the semi-finished product, and the order quantity of the ordered product, so that the semi-finished product held as inventory can be allocated to the ordered product most efficiently. Determine the combination of the allocation quantity from the semi-finished product to each ordered product.

For determining the combination of the appropriate quantities from each semi-finished product to each ordered product, for example, the linear programming method disclosed in Non-Patent Document 1 or the integer programming method for limiting the solution space to an integer can be used. In the method disclosed in Non-Patent Document 1, an evaluation function is set in consideration of various constraints for the allocated quantity of each semi-finished product for manufacturing each ordered product, so that the evaluation function is maximized. , The appropriate quantity of each semi-finished product for manufacturing each ordered product is determined to the optimum value.

In high-mix low-volume production such as build-to-order manufacturing, in order to determine the combination of the allocation quantity for each made-to-order product from each semi-finished product, it is important to determine whether or not the allocation is possible in the previous stage. That is, as a result of rigorously judging whether or not all combinations of each semi-finished product and each ordered product can be applied based on the judgment specification value of the internal standard, if there are few combinations that can be applied and many combinations that cannot be applied, each combination It becomes difficult to satisfactorily determine the combination of the appropriate quantity from the semi-finished product to each ordered product. However, in the above-mentioned Non-Patent Document 1, the determination of applicability is not examined.

The product combination whose characteristic value is not included in the determination specification value and is not included in the determination pending range is determined to be the second group.
The product combination that is not included in the determination specification value, is not included in the appropriable range, and is included in the determination pending range is determined to be the third group.

The second aspect of the present invention is
For each product combination of a plurality of types of ordered products and a plurality of types of semi-finished products held in inventory, the user determines whether or not the plurality of types of semi-finished products can be applied to the production of the plurality of types of ordered products. It is an appropriation work support device that supports the appropriation work to be judged respectively.
The ordered product information is acquired from the ordered product information storage unit that stores the ordered quantity and the predetermined judgment specification value in the predetermined judgment specification type of the plurality of types of ordered products as the ordered product information, and the plurality of types of semi-finished products are obtained. The semi-product information is acquired from the semi-product information storage unit that stores the stock quantity and the characteristic value in the determination specification type as semi-product information, and the characteristic value in the determination specification type of the plurality of types of semi-products is obtained. Of the judgment specification values in the judgment specification type of the plurality of types of ordered products, at least the appropriable range generated in advance using the judgment specification value and the appropriation / non-applicability judgment are suspended.

The determination processing unit
The product combination in which the characteristic value is included in the determination specification value and the product combination in which the characteristic value is not included in the determination specification value but is included in the applicable range are determined to be the first group.
The product combination whose characteristic value is not included in the determination specification value and is not included in the determination pending range is determined to be the second group.
The product combination that is not included in the determination specification value, is not included in the appropriable range, and is included in the determination pending range is determined to be the third group.

In these first and second aspects, the ordered product information is acquired from the ordered product information storage unit, the semi-product information is acquired from the semi-product information storage unit, and the diversion condition is acquired from the diversion condition storage unit. The characteristic values of the semi-finished products are compared with the judgment specification values, the appropriable range, and the judgment pending range, and the first group that can be appropriated for each product combination of a plurality of types of ordered products and a plurality of types of semi-finished products, It is determined by dividing it into a second group that cannot be applied and a third group that suspends the determination of whether or not it can be applied.

Conventionally, product combinations whose characteristic values are not included in the judgment specification value are uniformly judged to be the second group that cannot be applied. On the other hand, in this embodiment, the product combination whose characteristic value is included in the judgment specification value and the product combination whose characteristic value is not included in the judgment specification value and is included in the applicable range are the first group that can be applied. It is judged. A product combination whose characteristic value is not included in the determination specification value and is not included in the determination pending range is determined to be the second group that cannot be applied. A product combination whose characteristic value is not included in the judgment specification value, is not included in the appropriable range, and is included in the judgment pending range is determined to be the third group that suspends the applicability judgment.

Therefore, according to the first aspect and the second aspect, the product combination in which the characteristic value previously determined to be the unapplicable second group is not included in the determination specification value is also included in the pre-generated appropriable range. The product combinations that are used are judged to be the first group that can be applied. Therefore, the product combinations that can be applied can be expanded to a range in which the characteristic value, which was conventionally determined to be the second group that cannot be applied, is not included in the determination specification value. As a result, it is possible to improve the determination of appropriation or not and appropriately support the appropriation work.

In the first aspect, for example, in the determination step, the third group is referred to as a first determination entity group preset so that the first determination entity (for example, a person in charge of the production control department) determines whether or not to apply. , The second judgment entity (for example, the person in charge of the production engineering department) different from the first determination entity may be divided into the second determination entity group set in advance so as to determine the appropriation.

In the first aspect, for example, the ordered product information storage unit may store each of the determination specification values in a plurality of types of the determination specification types. The semi-finished product information storage unit may store each of the characteristic values in the plurality of types of the determination specification types. The diversion condition storage unit may store the appropriable range and the determination holding range, which are generated in advance for each determination specification type, in association with the determination specification type. In the determination step, the characteristic value is compared with the determination specification value, the appropriate range, and the determination pending range for each determination specification type, and for each of the product combinations, for each determination specification type, The determination may be made separately for the first group, the second group, and the third group. In the determination step, the determination result for each determination specification type may be used to classify each of the product combinations into the first group, the second group, and the third group.

In this embodiment, each determination specification value in the plurality of determination specification types is stored in the ordered product information storage unit. The characteristic values of each of the plurality of types of determination specifications are stored in the semi-product information storage unit. The appropriable range and the judgment holding range, which are generated in advance for each judgment specification type, are stored in the diversion condition storage unit in association with the judgment specification type. For each judgment specification type, the characteristic values of the semi-finished products are compared with the judgment specification value, the appropriable range, and the judgment pending range, and for each product combination, the first group, the second group, and the first group are compared for each judgment specification type. Judgment is made by dividing into 3 groups. Then, using the determination result for each determination specification type, each product combination is divided into a first group, a second group, and a third group for determination. Therefore, according to this aspect, the first group, the second group, and the third group are individually classified for each judgment specification type, and the judgment results are used to determine the product combination as a whole. The determination can be made by dividing into the first group, the second group, and the third group.

In the first aspect, for example, in the determination step, the determination result for each determination specification type determines that the product combination including the second group is the second group, and the determination result for each determination specification type. However, the product combination that does not include the second group but includes the third group is determined to be the third group, and the product combination in which the determination result for each determination specification type includes only the first group is determined. It may be determined that it is the first group.

When the judgment result for each judgment specification type includes the second group which cannot be applied, it is not appropriate to allocate the semi-finished product to the manufacture of the ordered product, but according to this aspect, for such a product combination. Is determined to be the second group, so that the semi-finished product can be prevented from being used for manufacturing the ordered product. When the judgment result for each judgment specification type does not include the second group but includes the third group, it is appropriate to suspend the judgment of appropriation / non-applicability, but according to this aspect, the product combination is the third group. Therefore, it is possible to suspend the determination of appropriation. When the judgment result for each judgment specification type includes only the first group, it is appropriate to allocate the semi-finished product to the manufacture of the ordered product, but according to this aspect, the product combination is the first group. Since the judgment is made, the semi-finished product can be used for manufacturing the ordered product.

In the first aspect, for example, in the diversion condition storage unit, the characteristic value in the determination specification type of the plurality of types of semi-finished products is compared with the determination specification value in the determination specification type of the plurality of types of ordered products. The product combination included in the appropriable range and the product combination included in the determination pending range specified based on the comparison result may be stored as the diversion condition. In the determination step, the first product combination in which the characteristic value matches the determination specification value and the product combination in which the characteristic value does not match the determination specification value and is included in the applicable range The product combination that is determined to be a group and whose characteristic value does not match the determination specification value and is not included in the appropriable range or the determination pending range is determined to be the second group and described as described above. The product combination whose characteristic value does not match the determination specification value, is not included in the appropriable range, and is included in the determination pending range may be determined to be the third group.

In this embodiment, the characteristic value in the judgment specification type of a plurality of types of semi-finished products and the judgment specification value in the judgment specification type of a plurality of types of ordered products are included in the applicable range specified based on the comparison result. The product combination and the product combination included in the determination pending range are stored in the diversion condition storage unit as diversion conditions.

Then, the product combination whose characteristic value matches the determination specification value and the product combination whose characteristic value does not match the determination specification value and is included in the applicable range are determined to be the applicable first group. A product combination whose characteristic value does not match the judgment specification value and is not included in the applicable range or the judgment pending range is determined to be the second group that cannot be applied. A product combination whose characteristic value does not match the judgment specification value, is not included in the appropriable range, and is included in the judgment pending range is determined to be the third group that suspends the applicability judgment.

Therefore, according to this aspect, even if the characteristic value does not match the determination specification value, the product combination included in the applicable range is determined to be the applicable first group. Therefore, the product combinations that can be applied can be expanded to a range in which the characteristic values do not match the judgment specification values. As a result, it is possible to improve the determination of appropriation or not and appropriately support the appropriation work.

In this embodiment, the determination specification type may be a material code representing a component or composition of a material forming the ordered product and the semi-finished product.

In the first aspect, for example, the determination specification value of the ordered product and the characteristic value of the semi-finished product may represent an order of superiority or inferiority in the determination specification type. The diversion condition storage unit stores as the applicable range a range in which the characteristic value in the determination specification type of the semi-finished product represents an order superior to the determination specification value of the ordered product by less than a predetermined threshold value. However, a range in which the characteristic value in the determination specification type of the semi-finished product represents a rank superior to the determination specification value of the ordered product by the threshold value or more may be stored as the determination holding range. The determination step can be applied to each of the product combinations when the characteristic value in the determination specification type of the semi-finished product represents the same order as the determination specification value in the determination specification type of the ordered product. When it is included in the range, it is determined that it is the first group, and the order in which the characteristic value in the judgment specification type of the semi-finished product is inferior to the judgment specification value in the judgment specification type of the ordered product. When representing, it may be determined to be the second group, and when the characteristic value in the determination specification type of the semi-finished product is included in the determination pending range, it may be determined to be the third group.

In terms of quality, there is no problem even if the characteristic value in the judgment specification type of the semi-finished product represents a rank superior to the judgment specification value of the ordered product, which is less than a predetermined threshold value. Therefore, in this aspect, such a range is stored as an appropriable range. The range in which the characteristic value in the judgment specification type of the semi-finished product represents a rank superior to the judgment specification value of the ordered product by a threshold value or more does not cause a problem in terms of quality, but if it is applied in terms of cost. Problems can occur. Therefore, in this aspect, such a range is stored as a determination pending range.

Then, for each product combination, when the characteristic value in the judgment specification type of the semi-finished product represents the same order as the judgment specification value in the judgment specification type of the ordered product, and when it is included in the applicable range, it is appropriated. It is determined to be the first possible group. When the characteristic value in the judgment specification type of the semi-finished product represents a rank inferior to the judgment specification value in the judgment specification type of the ordered product, it is determined to be the second group that cannot be applied. When the characteristic value in the judgment specification type of the semi-finished product is included in the judgment suspension range, it is determined to be the third group that suspends the determination of appropriation. Therefore, according to this aspect, it is possible to appropriately determine whether or not the appropriation is appropriate according to the order of superiority or inferiority in the determination specification type, which is represented by the determination specification value of the ordered product and the characteristic value of the semi-finished product.

In this embodiment, the determination specification type may be a quality rank representing the surface roughness of the ordered product and the semi-finished product.

In the first aspect, for example, the determination specification value in the determination specification type of the ordered product is represented by a first numerical value range equal to or more than a predetermined first lower limit value and less than or equal to a predetermined first upper limit value. You may. The characteristic value in the determination specification type of the semi-finished product may be represented by a numerical value. The diversion condition storage unit has a second numerical range that is equal to or greater than the first lower limit value and is greater than or equal to the first upper limit value and is equal to or less than the second upper limit value and excludes the first numerical range. A third numerical range that is stored as the appropriable range and is equal to or greater than the third lower limit value that is equal to or less than the second lower limit value and is less than or equal to the third upper limit value that exceeds the second upper limit value and is the second numerical value range. The range excluding the above may be stored as the determination pending range. In the determination step, for each of the product combinations, the first group when the characteristic value in the determination specification type of the semi-finished product is included in the first numerical range and when it is included in the appropriate range. When it is not included in the third numerical value range, it may be determined to be the second group, and when it is included in the determination pending range, it may be determined to be the third group.

In this embodiment, the judgment specification value in the judgment specification type of the ordered product is represented by the first numerical range which is equal to or more than the predetermined first lower limit value and equal to or less than the predetermined first upper limit value, and is represented by the judgment specification type of the semi-finished product. The characteristic value in is expressed numerically. The range excluding the first numerical range, which is the second numerical range equal to or greater than the first lower limit value and equal to or greater than the first upper limit value and equal to or less than the second upper limit value, is stored as the applicable range. The range excluding the second numerical value range, which is the third numerical value range which is equal to or less than the second lower limit value and is equal to or greater than the third lower limit value and exceeds the second upper limit value and is equal to or less than the third upper limit value, is stored as the determination pending range.

For each product combination, the characteristic value in the judgment specification type of the semi-finished product is judged as the first group when it is included in the first numerical range and when it is included in the applicable range, and is not included in the third numerical range. Sometimes it is determined to be the second group, and when it is included in the determination pending range, it is determined to be the third group. Therefore, according to this aspect, appropriation is appropriate according to the difference between the first numerical value range representing the judgment specification value in the judgment specification type of the ordered product and the numerical value representing the characteristic value in the judgment specification type of the semi-finished product. Can be determined.

In this embodiment, the determination specification type may be the length or weight of the ordered product and the semi-finished product.

In the first aspect, for example, for each of the product combinations, a display step of displaying the first group, the second group, and the third group on the display unit may be further provided.

In this aspect, for each product combination, the first group, the second group, and the third group are displayed on the display unit so as to be distinguishable. Therefore, according to this aspect, the user can determine whether or not to apply the third group, which holds the determination of whether or not to apply.

In the first aspect, for example, when the input unit is operated by the user to input that the product combination determined to be the third group in the determination step can be applied, the product combination is determined to be the third group. A modification step may be further provided to modify the product combination so that it can be applied.

In this aspect, with respect to the product combination determined to be the third group for which the determination of appropriation is suspended, when the input unit is operated by the user and it is input that the appropriation is possible, the product combination determined to be the third group is allocated. It will be fixed as possible. Therefore, according to this aspect, it is possible to incorporate the judgment of a person such as a user with respect to the product combination for which the judgment of appropriation is suspended. As a result, it is possible to improve the determination of appropriation or not and appropriately support the appropriation work.

According to the present invention, it is possible to improve the determination of appropriation or not and appropriately support the appropriation work.

(Knowledge on which the present invention is based)
First, the findings underlying the present invention will be explained. As described above, in the appropriation business, it is determined whether or not all product combinations of a plurality of types of semi-finished products and a plurality of types of ordered products held in inventory can be appropriated.

This appropriation criterion (judgment specification) is generally set so that the required specification value of the ordered product is satisfied with sufficient accuracy in the state where the ordered product is manufactured from the corresponding semi-finished product through the product processing process. It is set in anticipation of a certain margin of characteristic variation in the manufacturing process. For this reason, even if semi-finished products that are slightly below the judgment criteria are allocated, there is some risk that the quality yield of the final product will decrease, but it is considered that most products will be manufactured that meet the required specification values without any quality problems. Be done. In addition, although there is no problem in quality, judgment criteria are set so that the characteristic value indicating quality is regulated by a certain upper limit in order to prevent excessive quality and the manufacturing cost from rising more than necessary. It may have been done.

However, it may be necessary to have a large inventory quantity of semi-finished products in order to deal with all the ordered products with only semi-finished products that meet the judgment criteria set in anticipation of the above margin. On the other hand, if the criteria are loosened from the beginning and the range of semi-finished products that can be applied is expanded, the overall quality yield may decrease and the manufacturing cost may increase.

Therefore, first, the appropriation / non-applicability is determined using the determination criteria set in anticipation of the above-mentioned margin, and a combination of appropriation is created. If there is a problem such as the delivery date of the ordered product is not met or the inventory quantity of the semi-finished product becomes excessive, it is possible to allocate it even if some additional cost is incurred by loosening the judgment criteria at the discretion of the person. It is also possible to expand the range of semi-finished products. This makes it possible to manufacture a wide variety of products efficiently and while meeting the delivery date, using semi-finished products with a limited inventory quantity below a certain level.

Based on the above findings, the present inventor has come up with an invention capable of improving the determination of appropriation or not and appropriately supporting the appropriation work. That is, the technology disclosed in the present specification uses the criteria for determining appropriation, which are strictly set so as to be able to comply with restrictions such as quality and manufacturing cost with a margin as in the conventional case. It has a judgment standard that is relaxed from this strict judgment standard.

Then, it is determined that the semi-finished product that meets the strict judgment criteria can be allocated, and the allocation process is automatically executed. On the other hand, for semi-finished products that do not meet the strict criteria but meet the relaxed criteria, the appropriation judgment is suspended and the appropriation process is not automatically executed. Then, the appropriation process is executed only for the semi-finished products that the user has input as appropriable.

In this way, the range in which the criteria for semi-finished products can be relaxed without affecting the product quality is managed with human judgment. As a result, the allocation work can be appropriately supported. As a result, appropriation work that can comply with quality, manufacturing cost and delivery date in a well-balanced manner has been realized.

(Embodiment)
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In each drawing, the same reference numerals are used for the same components, and the description thereof will be omitted as appropriate.

(Constitution)
FIG. 1 is a block diagram schematically showing an example of the configuration of the allocation work support device according to the present embodiment. As shown in FIG. 1, the allocation business support device 100 in the present embodiment includes a display unit 110, an input unit 120, a memory 130, a storage device 140, and a central processing unit (CPU) 150. The appropriation work support device 100 supports the appropriation work. The appropriation business is a business of determining whether or not a semi-finished product held in inventory can be appropriated for manufacturing an ordered product, and putting the semi-finished product determined to be appropriable into a product processing process. The allocation business support device 100 is composed of computers such as a personal computer, a workstation, and a server.

The display unit 110 includes, for example, a liquid crystal display panel. The display unit 110 is controlled by the CPU 150 and displays, for example, the determination result of appropriation. The display unit 110 is not limited to the liquid crystal display panel. The display unit 110 may include other panels such as an organic EL (electroluminescence) panel.

The input unit 120 includes, for example, a mouse or a keyboard. When the input unit 120 is operated by the user, the input unit 120 outputs an operation signal indicating the operation content to the CPU 150. When the display unit 110 is a touch panel type display, the touch panel type display may also serve as the input unit 120 instead of the mouse or keyboard.

The memory 130 is composed of, for example, a semiconductor memory or the like. The memory 130 includes, for example, a read-only memory (ROM), a random access memory (RAM), an electrically erasable and rewritable ROM (EEPROM), and the like. For example, the ROM of the memory 130 stores a control program for operating the CPU 150.

The storage device 140 is composed of, for example, a hard disk, a semiconductor memory, or the like. The storage device 140 includes an order-made product information storage unit 141, a semi-product information storage unit 142, a diversion condition storage unit 143, an allocation instruction storage unit 144, and a solution search condition storage unit 145. Each storage unit 141 to 145 may be composed of different media from each other. Alternatively, each storage unit 141 to 145 may be composed of one medium in which the storage area is divided. Hereinafter, the information stored in the ordered product information storage unit 141, the semi-product information storage unit 142, and the diversion condition storage unit 143 will be described with reference to FIGS. 2 to 6. The information stored in the allocation instruction storage unit 144 and the solution search condition storage unit 145 will be described later.

FIG. 2 is a diagram schematically showing the ordered product information 200 stored in the ordered product information storage unit 141. The ordered product information 200 represents information about a product for which manufacturing has been ordered. As shown in FIG. 2, the ordered product information 200 includes the ordered product type 201 and the ordered quantity 202. The ordered product type 201 represents the type of the ordered product to which the semi-finished product has not yet been allocated. The order quantity 202 represents the quantity ordered for manufacturing the product type 201 of the corresponding ordered product.

The ordered product information 200 further includes a determination specification value for a semi-finished product in the determination specification type of the corresponding ordered product type 201. In this embodiment, the ordered product information 200 includes three types of determination specifications: material code 203, quality rank 204, and length 205.

The material code 203 represents a component or composition of a material constituting the semi-finished product as a determination specification value for the semi-finished product. In the present embodiment, the material code 203 is represented by, for example, a three-digit number. Basically, a semi-finished product having the same material code as the material code specified in the material code 203 of the ordered product information 200 is allocated. However, even if the material code is different, it may be applicable without any problem as long as it is suitable from the viewpoint of hardness or toughness.

Quality rank 204 represents the order of superiority or inferiority. Specifically, the quality rank 204 indicates, for example, the rank of the quality specification of the surface roughness as the determination specification value. In the present embodiment, the quality rank 204 is represented by five stages of ranks QR1 to QR5. Rank QR1 is the highest quality rank, and rank QR5 is the lowest quality rank. Semi-finished products with a rank lower than the rank specified in quality rank 204 cannot be allocated from the aspect of quality control. On the other hand, semi-finished products with a rank higher than the rank specified in quality rank 204 are usually not allocated because they become excessive quality and are disadvantageous in terms of cost, but they can be allocated in terms of quality, so they can be applied to the delivery date. It may be appropriated as needed, such as in time.

The length 205 represents a standard value of the length of the semi-finished product required to manufacture the corresponding product type 201 of the ordered product. Normally, there is no problem as long as it is in the range of ± 10% of the standard value specified in the length 205. Semi-finished products shorter than -10% of the standard value specified in length 205 cannot be applied because they are insufficient to manufacture the product. On the other hand, if a semi-finished product longer than + 10% of the standard value specified in the length 205 is used, the material yield will deteriorate, so it is not normally allocated, but it is allocated as needed, such as in time for delivery. May occur.

FIG. 3 is a diagram schematically showing semi-product information 300 stored in the semi-product information storage unit 142. Semi-product information 300 represents information about semi-finished products held in inventory. As shown in FIG. 3, the semi-finished product information 300 includes a semi-finished product production lot 301 and an inventory quantity 302. The semi-finished product production lot 301 represents a semi-finished product that is currently in stock and is not yet allocated to the product. The inventory quantity 302 represents the quantity held in stock in the production lot 301 of the corresponding semi-finished product.

Semi-finished products are managed by grouping semi-finished products with individual lot numbers according to attributes such as the same manufacturing date, manufacturing location, width, length, weight, and various performances. It is a number. For example, semi-finished products of the same material manufactured on different manufacturing dates are assigned individual lot numbers for each manufacturing date and are managed separately by grouping.

The semi-finished product information 300 further includes characteristic values in the determination specification type of the corresponding semi-finished product manufacturing lot 301. The judgment specification type included in the semi-product information 300 is the same as the judgment specification type included in the ordered product information 200. That is, in this embodiment, the semi-finished product information 300 includes a material code 303, a quality rank 304, and a length 305 as determination specification types.

The characteristic value in the determination specification type included in the semi-finished product information 300 is an actual value obtained by inspecting the semi-finished product included in the production lot 301 of the corresponding semi-finished product. When it is determined that the product combination of the characteristic value as the actual value of the production lot 301 of the semi-finished product and the judgment specification value of the product type 201 of the ordered product can be applied, the semi-finished product is allocated to the product type of the ordered product. Can be done.

FIG. 4 is a diagram schematically showing the material code condition 400 stored in the diversion condition storage unit 143. FIG. 5 is a diagram schematically showing the quality rank condition 500 stored in the diversion condition storage unit 143. FIG. 6 is a diagram schematically showing the length condition 600 stored in the diversion condition storage unit 143.

The diversion condition storage unit 143 can allocate the semi-finished product to the product type of the ordered product with respect to the product combination of the characteristic value of the manufacturing lot of the semi-finished product and the determination specification value of the product type of the ordered product, which was conventionally determined to be unapplicable. The diversion condition for determining that the item is appropriate and the diversion condition for suspending the determination of appropriation are stored. In the present embodiment, the diversion condition storage unit 143 stores the material code condition 400, the quality rank condition 500, and the length condition 600 as the diversion conditions.

As shown in FIG. 4, the material code condition 400 includes the material code 401 of the semi-finished product, the material code 402 of the ordered product, and the appropriation determination 403. The appropriation determination 403 indicates whether the combination of the material code 401 of the semi-finished product and the material code 402 of the ordered product determines whether it is "appropriate" or "suspends the determination of appropriation".

As described above, conventionally, when the material code of the semi-finished product and the material code of the ordered product are different, it has been determined that the appropriation is not possible. On the other hand, in the present embodiment, as shown in FIG. 4, among the product combinations whose material codes are different between the semi-finished product and the ordered product, the product combination determined to be applicable and the determination of applicability are determined. The pending product combination is included in the material code condition 400.

Under the material code condition 400 shown in FIG. 4, for example, the semi-finished product of the material code "101" is determined to be applicable to the ordered product of the material code "102", and the semi-finished product of the material code "101" is the semi-finished product of the material code "101". It is determined that it can be applied to the ordered product of "301". Further, for example, the semi-finished product of the material code "201" is suspended from the judgment of whether or not the semi-finished product of the material code "202" can be applied to the ordered product, and the semi-finished product of the material code "202" is transferred to the ordered product of the material code "201". Judgment of appropriation is pending.

The product combination determined to be applicable under the material code condition 400 is determined to be applicable in any case as in the case where the material code is the same, and the allocation process is automatically executed. On the other hand, a product combination for which the determination of appropriation is pending is determined by a person (for example, a person in charge of a factory) to be appropriable or unapplicable. For a product combination for which the determination of appropriation is suspended under the material code condition 400, for example, the person in charge of the production control department may determine the appropriation from the viewpoint of process control, for example, the person in charge of the production engineering department. The person may judge whether or not the appropriation is possible from a technical point of view.

For example, even if the material code of the production lot of the semi-finished product is not the same as the material code of the product type of the ordered product, if the semi-finished product is made of a similar material, there may be no problem in quality. Such a product combination may be set to "appropriate".

For example, a semi-finished product made of a stronger material is only disadvantageous in terms of cost and has no problem in terms of quality. For this reason, when the delivery date is tight, it may be preferable to accept the disadvantage in terms of cost and then allocate it. Such a product combination may be set to "judgment pending".

As shown in FIG. 5, the quality rank condition 500 includes the product type 501 of the ordered product, the quality rank 502, and the appropriation determination 503 of the higher rank. In the higher rank appropriation judgment 503, a semi-finished product having a quality rank higher than the quality rank 502 as a judgment specification value set for the product type 501 of the ordered product is judged to be "appropriate" or "allocated". Indicates whether to suspend the judgment of approval or disapproval.

In the past, it was determined that the appropriation was possible only when the quality rank of the semi-finished product and the quality rank of the ordered product matched, and it was determined that the appropriation was not possible when they were different. It is not possible in terms of quality control to allocate a production lot of a semi-finished product having a low quality rank to a variety of ordered products that require a high quality rank. However, semi-finished products having a rank higher than the rank specified in the quality rank 502 can be applied in terms of quality. Therefore, under the quality rank condition 500, the appropriation determination 503 of the higher rank is usually set to be appropriable.

However, under the quality rank condition 500 shown in FIG. 5, the determination of appropriation or non-appropriation is suspended for the higher rank of the quality rank of the ordered product product type "P002". This is because the quality rank 502 of the ordered product type "P002" is as low as "Rank QR4", so there is a high possibility that the judgment of appropriation is different depending on the quality rank of the semi-finished product.

For example, the person in charge of the production control department judges that the semi-finished products of "Rank QR3" can be applied, and the semi-finished products of "Rank QR1" and "Rank QR2" become excessive quality, which is a great disadvantage in terms of cost. Therefore, it may be determined that the appropriation is not possible. Alternatively, if it is absolutely necessary to meet the delivery date, the person in charge of the production management department determines that the semi-finished products of "Rank QR1" and "Rank QR2" can be applied to the ordered product type "P002". You may.

Under the quality rank condition 500 shown in FIG. 5, it is determined that the ordered product product type “P004” can be applied. As described above, the quality ranks in the judgment specification type of the ordered product are set to ranks QR1 to QR5, and there is no higher rank than rank QR1. However, the quality rank condition 500 shown in FIG. 5 indicates that if the quality rank of the semi-finished product is higher than the rank QR1, it is determined that the product can be applied.

As shown in FIG. 6, the length condition 600 includes the product type 601 of the ordered product, the specified value 602, the applicable 603, and the determination hold 604. The specified value 602 (corresponding to an example of the determination specification value) represents a value specified as the same normal applicable range as the conventional one for the product type 601 of the ordered product. At the specified value 602, the maximum value MAX (corresponding to an example of the first upper limit value) is set to + 20% of the standard value TYPE, and the minimum value MIN (corresponding to an example of the first lower limit value) is-of the standard value TYPE. It is set to 10%, and a range of -10% to + 20% of the standard value TYPE (corresponding to an example of the first numerical range) is defined as an applicable range.

Applicable 603 represents a value determined to be appropriable for the product type 601 of the ordered product. In the applicable 603, the minimum value MIN (corresponding to an example of the second lower limit value) is set to -10% of the standard value TYPE like the minimum value MIN of the specified value 602, and the maximum value MAX (second upper limit value). (Corresponding to one example) is set to + 20% of the standard value TYPE like the maximum value MAX of the specified value 602, and is in the range of -10% to + 20% of the standard value TYPE (as an example of the second numerical range). Equivalent) is specified as the applicable range.

As specified in the specified value 602, usually, the range of -10% to + 20% of the standard value TYPE is set to be applicable. On the other hand, in the present embodiment, as defined in the appropriable 603, the range from -10% to + 20% of the standard value TYPE is set to be appropriate, similarly to the specified value 602. As described above, in the present embodiment, the range of the applicable 603 is set in the same manner as the range of the specified value 602.

The determination hold 604 represents a value for which the determination of appropriation / non-applicability is suspended for the product type 601 of the ordered product. In the judgment hold 604, the minimum value MIN (corresponding to an example of the third lower limit value) is set to -20% of the standard value TYPE, and the maximum value MAX (the third upper limit value) is set, except for the product type "P004" of the ordered product. (Equivalent to one example) is set to + 50% of the standard value TYPE, and the range of -20% to + 50% of the standard value TYPE (corresponding to an example of the third numerical range) is a range for suspending the determination of appropriation. It is stipulated.

The appropriable 603 and the determination pending 604 set in this way need to comply with the specified value 602 in order to automatically determine that they can be applied, and when a standard relaxed from the specified value 602 is used. Means that it is necessary to judge whether or not a person can be appropriated.

Further, in the judgment pending 604, the minimum value MIN (corresponding to an example of the third lower limit value) and the maximum value MAX (corresponding to an example of the third upper limit value) are the same as the specified value 602 in the ordered product type “P004”. Is set to, and a range of -10% to + 20% of the standard value TYPE (corresponding to an example of the third numerical value range) is defined as a range for suspending the determination of appropriation. This indicates that it is necessary to comply with the specified value 602 for the ordered product product type "P004".

As described in Default 602 and Applicable 603, the minimum applicable MIN is usually set to -10% of the standard TYPE. On the other hand, the minimum value MIN is set to −20% of the standard value TYPE except for the product type “P004” of the ordered product of the judgment pending 604. Therefore, for example, a person in charge of the technical department may determine whether or not the allocation can be made individually from a technical point of view.

Further, in the determination hold 604, the maximum value MAX is set to + 50% of the standard value TYPE except for the ordered product type “P004”. Therefore, for example, the person in charge of the production management department may determine whether or not it can be applied individually from the viewpoint of whether or not it is necessary to meet the delivery date.

In the length condition 600 of FIG. 6, the range of the appropriable 603 overlaps with the range of the specified value 602, and the range of the determination hold 604 overlaps with the range of the appropriable 603. As for these overlapping ranges, the higher range has priority. That is, of the range of 603 that can be applied (corresponding to an example of the second numerical range), the range excluding the range of the specified value 602 (corresponding to an example of the first numerical range) is the range that is determined to be applicable. Of the range of determination pending 604 (corresponding to an example of the third numerical range), the range excluding the range of appropriable 603 (corresponding to an example of the second numerical range) is the range for suspending the determination of appropriation.

Returning to FIG. 1, the CPU 150 has the functions of the acquisition processing unit 151, the determination processing unit 152, and the allocation processing unit 153 by operating according to the control program stored in the memory 130. The allocation processing unit 153 includes an automatic calculation processing unit 1531, a display control unit 1532, and a correction processing unit 1533.

The acquisition processing unit 151 acquires the ordered product information 200 from the ordered product information storage unit 141. The acquisition processing unit 151 acquires the semi-product information 300 from the semi-product information storage unit 142. The acquisition processing unit 151 acquires the material code condition 400, the quality rank condition 500, and the length condition 600 from the diversion condition storage unit 143.

The determination processing unit 152 includes all the varieties included in the ordered product type 201 of the ordered product information 200 and all the production lots included in the semi-finished product production lot 301 of the semi-product information 300. Regarding the product combination, it is determined whether or not the product combination can be applied by using the diversion conditions (material code condition 400, quality rank condition 500, length condition 600 in this embodiment) stored in the diversion condition storage unit 143. The determination processing unit 152 generates determination result information 700 (FIG. 7) representing the determination result of appropriation.

FIG. 7 is a diagram schematically showing the determination result information 700. In the present embodiment, the ordered product information 200 (FIG. 2) includes five types of ordered product product types 201, and the semi-product information 300 (FIG. 3) includes five types of semi-finished product production lots 301. There is. Therefore, as shown in FIG. 7, the determination result information 700 represents the determination result of appropriation / non-applicability for a total of 25 types of product combinations.

As shown in FIG. 7, the determination result information 700 includes the product type 701 of the ordered product, the manufacturing lot 702 of the semi-finished product, the determination result 703 of the material code, the determination result 704 of the quality rank, the determination result 705 of the length, and the comprehensive determination. Results 706 are included.

As shown in FIG. 7, the determination results 703 to 706 are represented by the symbols “⊚”, “◯”, “Δ”, and “x”. The symbol "◎" indicates that the applicability has been determined based on the criteria based on the specified value, as in the conventional case. That is, for example, in the material code, when the material code specified in the product type 701 of the ordered product and the material code of the semi-finished product production lot 702 are the same, they are represented by the symbol “⊚”. For example, in the quality rank, when the quality rank specified in the ordered product product type 701 and the quality rank of the semi-finished product production lot 702 are the same, they are represented by the symbol “⊚”. For example, the length is represented by the symbol “⊚” when the specified value specified for the product type 701 of the ordered product includes the length of the manufacturing lot 702 of the semi-finished product.

The symbol “◯” indicates that it is determined that the diversion condition (material code condition 400, quality rank condition 500, length condition 600 in the present embodiment) stored in the diversion condition storage unit 143 can be applied. The symbol “Δ” indicates that the determination has been put on hold due to the diversion condition stored in the diversion condition storage unit 143. The symbol "x" indicates that it has been determined that it cannot be applied. Whether or not the product combination of the symbol "Δ" can be applied is determined by the judgment of a person (for example, the person in charge of the factory) as described above.

First, the determination processing unit 152 individually determines whether or not 25 types of product combinations can be applied for each determination specification type, that is, for each "material code", "quality rank", and "length". In FIG. 7, for example, a product combination in which the product type 701 of the ordered product is “P001” and the production lot 702 of the semi-finished product is “I001” is described.

Regarding the "material code", as can be seen from FIG. 2, the "material code" of the ordered product type "P001" is "101", and as can be seen from FIG. 3, the "material code" of the semi-finished product production lot "I001". Is "101", which is the same. Therefore, the determination result 703 of the material code is represented by the symbol “⊚”.

Regarding the "quality rank", as can be seen from FIG. 2, the "quality rank" of the ordered product type "P001" is "QR2", and as can be seen from FIG. 3, the "quality rank" of the semi-finished product production lot "I001". Is "QR2" and is the same. Therefore, the quality rank determination result 704 is represented by the symbol “⊚”.

Regarding the "length", as can be seen from FIG. 6, the specified values of the ordered product product type "P001" are 9 for the minimum value MIN and 11 for the maximum value MAX, and as can be seen from FIG. 3, the semi-finished product production lot " The "length" of "I001" is "11" and is included in the specified value. Therefore, the length determination result 705 is represented by the symbol “⊚”.

Next, the determination processing unit 152 obtains the comprehensive determination result 706 of the product combination from the individual appropriation / non-applicability determination results for each of the "material code", "quality rank", and "length". The determination processing unit 152 defines the symbol "◎" as the highest level and the symbol "x" as the lowest level in the order of the symbols "◎", "○", "Δ", and "x". Then, the determination processing unit 152 sets the lowest determination result in the individual appropriation / non-applicability determination result as the comprehensive determination result 706 of the product combination.

For example, in the product combination in which the product type 701 of the ordered product is "P001" and the production lot 702 of the semi-finished product is "I001", the individual appropriation / non-applicability determination results are all represented by the symbol "⊚". Therefore, as shown in FIG. 7, the comprehensive determination result 706 is represented by the symbol “⊚”. For example, in the product combination in which the product type 701 of the ordered product is "P002" and the production lot 702 of the semi-finished product is "I001", the individual appropriation / disapproval judgment results are represented by the symbols "○", "△", and "◎". Has been done. Therefore, as shown in FIG. 7, the comprehensive determination result 706 is represented by the symbol “Δ”. For example, in the product combination in which the product type 701 of the ordered product is "P005" and the production lot 702 of the semi-finished product is "I002", the individual appropriation / disapproval judgment results are represented by the symbols "○", "×", and "◎". Will be done. Therefore, as shown in FIG. 7, the comprehensive determination result 706 is represented by the symbol “x”.

Returning to FIG. 1, the allocation processing unit 153 acquires the determination result information 700 from the determination processing unit 152. The appropriation processing unit 153 generates appropriation availability information 800 (FIG. 8) by using the total determination result 706 of the acquired determination result information 700.

FIG. 8 is a diagram schematically showing appropriation availability information 800. Appropriation availability information 800 indicates appropriation availability for each product combination of the product type of the ordered product and the production lot of the semi-finished product. In the present embodiment, the appropriation availability information 800 includes the types of ordered products in the first row, the ordered quantity in the second row, the production lots of semi-finished products in the first column, and the second column. Stock quantities are listed and presented in tabular form. The appropriation availability information 800 includes information obtained by adding the order quantity and the inventory quantity to the comprehensive determination result 706 of the determination result information 700 shown in FIG. 7.

Returning to FIG. 1, the automatic calculation processing unit 1531 of the appropriation processing unit 153 automatically performs the appropriation calculation using the production lot of the semi-finished product determined to be appropriable. The allocation calculation performed by the automatic calculation processing unit 1531 will be described in detail later.

FIG. 9 is a diagram schematically showing the first allocation combination information 900. The first allocation combination information 900 represents the result of allocation calculation performed by the automatic calculation processing unit 1531 using only specified values. That is, the first appropriation combination information 900 represents the result of the appropriation calculation using only the semi-finished products represented by the symbol “⊚” in the appropriation availability information 800 of FIG.

In FIG. 9, the semi-finished product production lot "I001" is allocated to the ordered product type "P001" whose order quantity is 10, and the inventory quantity of the semi-finished product production lot "I001" is changed from 20 to 10. is decreasing. The semi-finished product production lot "I004" is allocated to the ordered product type "P004" with an order quantity of 5, and the inventory quantity of the semi-finished product production lot "I004" is reduced from 10 to 5. .. The semi-finished product production lot "I005" is allocated to the ordered product type "P005" with an order quantity of 20 pieces, and the inventory quantity of the semi-finished product production lot "I005" is reduced from 30 pieces to 20 pieces. doing. As a result of these allocations, in FIG. 9, the allocations for the ordered product varieties "P002", "P003", and "P005" remain.

FIG. 10 is a diagram schematically showing the second allocation combination information 1000. The second allocation combination information 1000 includes the result of allocation calculation including those determined to be applicable under the diversion conditions (material code condition 400, quality rank condition 500, length condition 600 in this embodiment). Represent. That is, the second appropriation combination information 1000 represents the result of the appropriation calculation performed using the semi-finished products represented by the symbols “⊚” and the symbol “◯” in the appropriation availability information 800 of FIG.

In FIG. 10, the semi-finished product production lot "I001" is allocated to the ordered product type "P001" with an unallocated remaining amount of 10 pieces, and the inventory quantity of the semi-finished product production lot "I001" is from 10 pieces. It has decreased to 0. As a result of this allocation, in FIG. 10, the allocation for the ordered product varieties "P002" and "P003" remains.

In this embodiment, the automatic calculation processing unit 1531 of the allocation processing unit 153 uses the semi-finished products represented by the symbols “◎” and the symbol “○” in the appropriation availability information 800 of FIG. 8 from the beginning to perform appropriation calculation. I do. That is, in the present embodiment, the automatic calculation processing unit 1531 does not calculate the second allocation combination information 1000 shown in FIG. 10 after calculating the first allocation combination information 900 shown in FIG. 9, but from the beginning. , The second allocation combination information 1000 shown in FIG. 10 is calculated.

Returning to FIG. 1, the display control unit 1532 of the allocation processing unit 153 displays the result of the allocation calculation when the product type of the ordered product that has not been allocated remains as a result of the allocation calculation executed by the automatic calculation processing unit 1531. It is displayed on the unit 110. The display control unit 1532 displays, for example, the second allocation combination information 1000 shown in FIG. 10 on the display unit 110.

The user looks at the second appropriation combination information 1000 displayed on the display unit 110, and determines whether or not the product combination represented by the symbol “Δ” (that is, the determination of appropriation is suspended) can be appropriated. To do. If the product combination represented by the symbol "△" is, for example, a product combination that can be judged by the person in charge of the production control department from the viewpoint of process control, the user can ask the person in charge of the production control department to make a judgment. Good. If the product combination represented by the symbol "△" is, for example, a product combination that can be judged from a technical point of view by the person in charge of the production engineering department, the user may ask the person in charge of the production engineering department to make a judgment. ..

When an instruction for appropriation for a product combination represented by the symbol “Δ” is input using the input unit 120, the correction processing unit 1533 of the appropriation processing unit 153 produces a semi-finished product production lot corresponding to the product combination. Appropriate to the corresponding product type of the ordered product.

FIG. 11 is a diagram schematically showing final allocation combination information 1100. The final allocation combination information 1100 represents the final allocation result including the allocation indicated by using the input unit 120.

Among the product combinations represented by the symbols “Δ” in FIG. 10, in FIG. 11, 10 semi-finished product manufacturing lots “I002” and 20 semi-finished product manufacturing lots “I005” are ordered products. It has been allocated to the product type "P002", and the application of the ordered product type "P002" has been completed. Further, the production lot "I003" of 10 semi-finished products has been allocated to the ordered product product type "P003", and the allocation of the ordered product product type "P003" has been completed.

The correction processing unit 1533 stores the final allocation combination information 1100 obtained by the operation of the input unit 120 in the allocation instruction storage unit 144. The correction processing unit 1533 reflects the contents of the final allocation combination information 1100 in the stored contents of the ordered product information storage unit 141 and the semi-product information storage unit 142.

That is, the correction processing unit 1533 completes the allocation of the ordered product types "P001", "P002", "P003", "P004", and "P005" stored in the ordered product information storage unit 141 (that is, the allocation balance is Change to zero). The correction processing unit 1533 changes the inventory quantity of the semi-finished product production lots "I001", "I002", "I003", and "I005" stored in the semi-finished product information storage unit 142 to "zero", and semi-finished products. The inventory quantity of the production lot "I004" is changed to "5". As a result, the ordered product varieties "P001", "P002", "P003", "P004", and "P005" are excluded from the next appropriation determination target.

(motion)
12 and 13 are flowcharts schematically showing the operation of the allocation business support device 100 shown in FIG.

In step S1200 (corresponding to an example of the first acquisition step), the CPU 150 acquires the ordered product information 200 from the ordered product information storage unit 141 and stores it in the memory 130. In step S1205 (corresponding to an example of the second acquisition step), the CPU 150 acquires the semi-product information 300 from the semi-product information storage unit 142 and stores it in the memory 130. In step S1210 (corresponding to an example of the third acquisition step), the CPU 150 acquires the diversion conditions (material code condition 400, quality rank condition 500, length condition 600 in this embodiment) from the diversion condition storage unit 143. , Saved in memory 130.

In step S1215, the determination processing unit 152 individually determines whether or not to apply each of the determination specification types (in this embodiment, each of the "material code", "quality rank", and "length"). In step S1220 (corresponding to an example of the determination step), the determination processing unit 152 determines the overall appropriation availability for each product combination based on the individual appropriation availability determination results. Based on these determination results, the determination processing unit 152 generates determination result information 700 (FIG. 7).

In step S1225, the automatic calculation processing unit 1531 of the allocation processing unit 153 automatically calculates the allocation processing using the product combinations represented by the symbols “⊚” and “◯”. In step S1230, the appropriation processing unit 153 determines, as a result of the automatic calculation, whether or not there are any varieties of ordered products that have not yet been allocated. If there is no product type of the ordered product that has not been allocated yet (NO in step S1230), the operations of FIGS. 12 and 13 are terminated. For example, as shown in FIG. 10, if there is a product type of the ordered product that has not yet been allocated (YES in step S1230), the process proceeds to step S1235.

In step S1235 (corresponding to an example of the display step), the display control unit 1532 of the allocation processing unit 153 displays the allocation result by automatic calculation. In step S1240, the correction processing unit 1533 of the allocation processing unit 153 determines whether or not there is an allocation input operation using the input unit 120 by the user. If there is no allocation input operation (NO in step S1240), the process returns to step S1235, and the display of the allocation result is continued. On the other hand, if there is an allocation input operation (YES in step S1240), the process proceeds to step S1300 in FIG.

In step S1300 (corresponding to an example of the correction step), the display control unit 1532 of the allocation processing unit 153 corrects the allocation result according to the allocation input operation using the input unit 120 by the user, and displays the corrected allocation result. To do. In step S1305, the appropriation processing unit 153 determines whether or not there are still product varieties of the ordered product that have not yet been allocated. If there is no product type of the ordered product that has not been allocated yet (NO in step S1305), the operations of FIGS. 12 and 13 are terminated. If there are still varieties of ordered products that have not been allocated (YES in step S1305), the process proceeds to step S1310.

In step S1310, the correction processing unit 1533 of the allocation processing unit 153 determines whether or not there is an allocation input operation using the input unit 120 by the user. If there is no allocation input operation (NO in step S1310), the allocation input operation is waited for. On the other hand, if there is an allocation input operation (YES in step S1310), the process returns to step S1300. As a result, the operations of FIGS. 12 and 13 are continued until there are no unallocated product types of the ordered product.

(Automatic calculation by the automatic calculation processing unit)
FIG. 14 is a block diagram schematically showing an example of the configuration of the automatic calculation processing unit 1531. The configuration of the automatic calculation processing unit 1531 will be described in detail with reference to FIG.

In FIG. 1, the solution search condition storage unit 145 of the storage device 140 determines, for example, the priority of allocating the production lot of a specific semi-finished product to the product type of each ordered product, the appropriation availability information, the loop number setting value N, and the like. Stores the information required to determine the number of production lots for each semi-finished product for each ordered product variety.

The ordered product information storage unit 141 may further store, for example, price, use, function, storage period, size, lower limit of the number of appropriations, and the like as information on the ordered product. The semi-finished product information storage unit 142 may further store, for example, expiration date, size, function, use, and the like as information about the semi-finished product.

As shown in FIG. 14, the automatic calculation processing unit 1531 includes an initial solution setting unit 42, a counter unit 43, a counter value determination unit 44, an allocation number change unit 45, a lot number determination unit 46, a lot number correction unit 47, and allocation. It includes a number determination unit 48, a first allocation number correction unit 49, an inventory quantity determination unit 50, a second allocation number correction unit 51, an evaluation value comparison unit 52, and an allocation combination update unit 53.

The initial solution setting unit 42 sets the initial solution of the allocation combination solution by reading the initial solution of the allocation combination solution stored in the solution search condition storage unit 145. The initial solution of the allocation combination solution may be, for example, one input by the user in the input unit 120 and stored in the solution search condition storage unit 145. Alternatively, the initial solution of the allocation combination solution may be, for example, one in which the automatic calculation processing unit 1531 randomly selects a positive integer and stores it in the solution search condition storage unit 145.

The counter unit 43 sets the value of the counter C according to the number of times the specific number of allocations of 1 is changed in the allocation combination solution. For example, when the allocation combination solution is the initial solution, that is, when the number of allocations is changed to 0, the counter unit 43 sets the value of the counter C to 0, and then allocates a specific 1 in the allocation combination solution. The value of the counter C is incremented by 1 according to the number of times the number is changed.

The counter value determination unit 44 determines whether or not the value of the counter C is equal to the loop number set value N set in advance by the user. Specifically, when the value of the counter C becomes a value equal to the loop number setting value N, the counter value determination unit 44 determines that the appropriate number has been changed by the number of times of the loop number setting value N, and determines that the counter has been changed. When the value of C has not reached the loop number setting value N, it is determined that the appropriate number should be further changed. The loop number setting value N is, for example, a value such as 100 or 1000, is arbitrarily set by the user, and is stored in the solution search condition storage unit 145.

The appropriation number changing unit 45 determines that the appropriation number should be changed by the counter value determination unit 44, and when it is determined that the appropriation number should be changed, the appropriation number changing unit 45 of the specific one semi-finished product for manufacturing the ordered product of the specific one of the appropriation combination solutions Randomly set the number of allocations from an integer of 0 or more and up to the smaller of the number of semi-finished products required to manufacture the ordered product or the quantity of semi-finished products in stock, whichever is smaller. change.

The lot number determination unit 46 determines whether or not the number of types of semi-finished products to be allocated for manufacturing the ordered product manufactured by using the semi-finished products with the changed allocation number satisfies the lot number constraint condition. More specifically, the upper limit of the number of types of semi-finished products allowed to manufacture the ordered product is set in advance according to each ordered product. The lot number determination unit 46 determines that the lot number constraint condition is satisfied when the number of types of semi-finished products allocated to the ordered product is equal to or less than the upper limit, and the number of types of semi-finished products allocated to the ordered product is the upper limit. If the value is exceeded, it is determined that the lot number constraint condition is not satisfied.

When the lot number correction unit 47 determines that the lot number determination unit 46 does not satisfy the lot number constraint condition, the lot number correction unit 47 determines that the number of semi-finished products allocated to manufacture the ordered product other than the semi-finished product whose allocation number has been changed is 0. Correct to. As a result, the number of types of semi-finished products allocated to the ordered product can be reduced by 1, and the number of semi-finished products allocated can be modified so as to satisfy the lot number constraint condition.

The appropriation number determination unit 48 manufactures the ordered product P by the total of the appropriations of all the semi-finished products allocated to manufacture the specific one ordered product P manufactured by using the semi-finished product whose appropriation number is changed. Determine whether or not the total number of semi-finished products required to do so is satisfied. Specifically, the number of semi-finished products to be allocated to manufacture the ordered product (that is, the ordered quantity) is preset according to each ordered product. The allocation number determination unit 48 satisfies the total allocation number constraint condition when the total allocation number of the semi-finished products to be allocated to the ordered product is less than or equal to the allocation number of the semi-finished products to be allocated to the ordered product (that is, the order quantity). Then it is determined. When the total number of semi-finished products to be allocated to the ordered product exceeds the number of semi-finished products to be allocated to the ordered product (that is, the ordered quantity), the appropriation number determination unit 48 sets the total appropriation number constraint condition. Judge that it is not satisfied.

When the first appropriation number correction unit 49 determines that the appropriation number determination unit 48 does not satisfy the total appropriation number constraint condition, the appropriation number of semi-finished products required to manufacture the ordered product from the total appropriation number (that is, Set an arbitrary natural number up to the value obtained by subtracting the order quantity), and allocate the semi-finished products other than the semi-finished products whose allocation number is changed among all the semi-finished products to be allocated to manufacture the ordered product. The allocation number obtained by subtracting the natural number from the number is set as the new allocation number. In this way, the first allocation number correction unit 49 can correct the allocation number of the semi-finished products so as to satisfy the total allocation number constraint condition by subtracting the allocation number of the semi-finished products that do not satisfy the total allocation number constraint condition. it can.

The inventory quantity determination unit 50 determines whether or not the total of all the allocated numbers of the semi-finished products whose allocation numbers have been changed satisfies the inventory quantity constraint condition of the semi-finished products. Specifically, the inventory quantity is set in advance according to the semi-finished product. The inventory quantity determination unit 50 determines that the inventory quantity constraint condition is satisfied when the total of all the allocated numbers of the semi-finished products whose allocation numbers have been changed is equal to or less than the inventory quantity of the semi-finished products. The inventory quantity determination unit 50 determines that the inventory quantity constraint condition is not satisfied when the total of all the allocated numbers of the semi-finished products whose allocation numbers have been changed exceeds the inventory quantity of the semi-finished products.

When the inventory quantity determination unit 50 determines that the inventory quantity constraint condition is not satisfied, the second allocation number correction unit 51 subtracts the inventory quantity of the semi-finished product from the total allocation number of the semi-finished products whose allocation number is changed. An arbitrary natural number up to the obtained value is set, and the allocation number obtained by subtracting the natural number from the allocation number of the semi-finished products other than the semi-finished product whose allocation number is changed is set as the new allocation number. By subtracting the allocation number of the semi-finished products that do not satisfy the inventory quantity constraint condition by the second allocation number correction unit 51 in this way, the allocation number of the semi-finished products can be corrected so as to satisfy the inventory quantity constraint condition.

The evaluation value comparison unit 52 evaluates the evaluation value of the allocation combination solution and the allocation combination solution (hereinafter, also referred to as “provisional allocation combination solution”) after changing the allocation number of a specific 1 in the allocation combination solution. Calculate values and compare them.

As a result of comparison by the evaluation value comparison unit 52, the appropriation combination update unit 53 determines that the evaluation value of the appropriation combination solution after changing the appropriation number is equal to or greater than the evaluation value of the appropriation combination solution before the appropriation number is changed. The appropriation combination solution after changing the appropriation number is rewritten with a new appropriation combination solution.

FIG. 15 is a flowchart schematically showing an example of the procedure for automatic calculation of allocation executed by the automatic calculation processing unit 1531. The automatic calculation processing unit 1531 determines an allocation combination solution in which a combination of the allocation numbers of one or a plurality of types of semi-finished products to be allocated for manufacturing the same or different types of ordered products is set.

The CPU 150 starts the operation shown in FIG. 15 after reading the data regarding the constraint conditions related to the allocation process stored in the solution search condition storage unit 145.

First, the initial solution setting unit 42 sets the initial solution of the allocation combination solution (step S1). Next, the counter unit 43 sets the value of the counter C, which indicates the number of times the allocation number of the allocation combination solution is changed, to 0 (step S2). Next, the counter value determination unit 44 determines whether or not the value of the counter C is equal to the loop number setting value N (step S3).

Then, when the value of the counter C is equal to the loop number setting value N (YES in step S3), the automatic calculation processing unit 1531 stores the allocation combination solution stored in the memory 130 as the optimum solution in the memory 130, and FIG. Ends the processing of. On the other hand, when the value of the counter C is not equal to the loop number setting value N (NO in step S3), the counter unit 43 adds 1 to the value of the counter C (step S4).

Next, the appropriation number changing unit 45 sets the appropriation number of the specific 1 semi-finished product for manufacturing the ordered product of the specific 1 in the appropriation combination solution to an integer of 0 or more and the ordered product. The number of semi-finished products required for manufacturing (that is, the quantity ordered) or the quantity of semi-finished products in stock, whichever is smaller, is randomly changed from among integers up to the smaller value (step S5).

Next, the lot number determination unit 46 determines that the number of types of semi-finished products to be allocated for manufacturing the ordered semi-finished product manufactured by using the semi-finished product whose allocation number is changed is the half allowed to manufacture the ordered product. It is determined whether or not the number of product types is equal to or less than the upper limit (step S6). Then, when the number of types of semi-finished products allocated to manufacture the ordered product exceeds the upper limit of the number of semi-finished products allowed to manufacture the ordered product (NO in step S6), the number of lots is corrected. In section 47, the number of semi-finished products to be allocated for manufacturing the ordered product other than the semi-finished product whose allocation number has been changed is set to 0 (step S7). On the other hand, when the number of types of semi-finished products allocated to manufacture the ordered product is less than or equal to the upper limit of the number of types of semi-finished products allowed to manufacture the ordered product (YES in step S6), the process is stepped. Proceed to S8.

In step S8, the appropriation number determination unit 48 determines that the sum of the appropriation numbers of all the semi-finished products allocated to manufacture the specific ordered product P manufactured by using the semi-finished products whose appropriation numbers are changed is the order. It is determined whether or not the number of semi-finished products required to manufacture the product P is larger than the number of appropriations (that is, the ordered quantity of the ordered product P). Then, the total number of all semi-finished products allocated to manufacture the ordered product P is larger than the total number of semi-finished products required to manufacture the ordered product P (that is, the ordered quantity of the ordered product P). If (NO in step S8), the process proceeds to step S9.

In step S9, the first appropriation number correction unit 49 is a value obtained by subtracting the appropriation number of the semi-finished products required for manufacturing the ordered product P (that is, the ordered quantity of the ordered product P) from the total appropriation number. Of all the semi-finished products allocated to manufacture the ordered product P by setting an arbitrary natural number up to the upper limit, the allocated number obtained by subtracting the natural number from the allocated number of the semi-finished products other than the semi-finished products whose allocation number has been changed. Is set to a new allocation number, and the process returns to step S8. On the other hand, when the total number of all semi-finished products allocated to manufacture the ordered product P is less than or equal to the number of semi-finished products required to manufacture the ordered product P (that is, the ordered quantity of the ordered product P). (YES in step S8), the process proceeds to step S10.

In step S10, the inventory quantity determination unit 50 determines whether or not the total of all the allocated numbers of the semi-finished products Q whose allocated numbers have been changed is larger than the inventory quantity of the semi-finished products Q whose allocated numbers have been changed in the provisional allocation combination solution. To judge. Then, when the total of all the allocated numbers of the semi-finished product Q is larger than the inventory quantity of the semi-finished product Q (NO in step S10), the process proceeds to step S11.

In step S11, the second allocation number correction unit 51 sets an arbitrary natural number up to a value obtained by subtracting the inventory quantity of the semi-finished product Q from the total allocation number of the semi-finished product Q whose allocation number has been changed. Then, the new allocation number is set by subtracting the natural number from the allocation number of the semi-finished products other than the semi-finished product Q for which the allocation number has been changed. On the other hand, when the total of all the allocated numbers of the semi-finished product Q is equal to or less than the inventory quantity of the semi-finished product Q (YES in step S10), the process proceeds to step S12.

In step S12, the evaluation value comparison unit 52 calculates the evaluation value A of the allocation combination solution and the evaluation value B of the provisional allocation combination solution, and compares the evaluation value A with the evaluation value B. Then, when the evaluation value B of the provisional allocation combination solution is less than the evaluation value A of the allocation combination solution (NO in step S12), the allocation combination solution is not changed and the process returns to step S3. On the other hand, when the evaluation value B of the provisional allocation combination solution is equal to or higher than the evaluation value A of the allocation combination solution (YES in step S12), the allocation combination update unit 53 rewrites the provisional allocation combination solution to a new allocation combination solution (step S13). ). After that, the process returns to step S3.

As described above, the counter unit 43 increments the value of the counter C by 1, and repeats each step of steps S3 to S13 until the value of the counter C reaches the loop number setting value N. By rewriting the appropriation combination solution in this way, the appropriation combination solution is brought closer to the optimum solution.

Such appropriation processing by the automatic calculation processing unit 1531 is arbitrary in an appropriation combination solution in which a combination of appropriation numbers of one or more semi-finished products to be allocated for manufacturing the same or different types of ordered products is set. The first step (step S5) of creating a provisional allocation combination solution in which the allocation number of any one type of semi-finished product is changed for one type of ordered product, the evaluation value A of the allocation combination solution, and the evaluation of the provisional allocation combination solution. The value B is calculated, and when the evaluation value B of the provisional allocation combination solution is less than the evaluation value A of the allocation combination solution, the allocation combination solution is not changed, and the evaluation value B of the provisional allocation combination solution is the evaluation value A of the allocation combination solution. In the above case, the first step and the second step are performed one or more times, including a second step (step S13) of rewriting the provisional allocation combination solution to a new allocation combination solution.

By sequentially rewriting the allocation combination solution based on the local search method that combines the first and second steps, the allocation number of each semi-finished product for each ordered product can be brought closer to the optimum solution. Then, the more times the first step and the second step are executed while changing the combination of the ordered product and the semi-finished product (that is, the more times the allocation combination solution is rewritten), the more the allocation combination solution becomes the optimum solution. You can get closer.

The appropriation process by the automatic calculation processing unit 1531 of the present embodiment is a combination of the first step and the second step when a quasi-global constraint condition is imposed on the provisional appropriation combination solution created in the first step. In between, correction steps (steps S7, S9 and S11) according to the constraint conditions are added, and the provisional allocation combination solution is corrected by the correction step. As the above-mentioned semi-global constraint condition, for example, when an upper limit of the number of semi-finished products to be allocated for manufacturing a specific ordered product is set (step S8: total quota constraint condition), the semi-finished product When the upper limit of the inventory quantity is set (step S10: inventory quantity constraint condition), when the upper limit of the number of types of semi-finished products to be used for manufacturing one ordered product is set (step S6: number of lots). Constraints), when semi-finished products are divided into multiple groups and it is set that semi-finished products of a specific group should be used to manufacture a specific ordered product (not shown: group constraint), etc. Can be considered. Each of these constraints and each modification step of modifying the allocation number so as to satisfy each constraint will be described later.

For each process shown in FIG. 15 of the allocation process by the automatic calculation processing unit 1531, for example, when determining the combination of the allocation numbers of the production lots of each semi-finished product with respect to the allocation combination solution shown in FIG. Is explained.

FIG. 16 is a diagram showing an example of an allocation combination solution in which the allocation number of the production lots of the five types of semi-finished products allocated for producing the varieties of the five types of ordered products is set. In FIG. 16, specifically, the allocation numbers of the production lots A001 to A002 and B001 to B003 of each semi-finished product to be allocated to the varieties J001 to J005 of each ordered product are set. As shown in FIG. 16, the number of semi-finished product production lots allocated to manufacture one type of ordered product is set. For example, for the ordered product type J001, the number of allocations of the semi-finished product production lot A001 is 2, the number of allocations of the semi-product production lot A002 is 0, the number of allocations of the semi-product production lot B001 is 1, and the number of semi-finished products. The number of allocations of the production lot B002 of the above is 0, and the number of allocations of the semi-finished production lot B003 is 1.

As described above, semi-finished products are grouped by assigning individual lot numbers to the semi-finished products according to attributes such as the same manufacturing date, manufacturing location, width, length, weight, and various performances. This is the control number of the semi-finished product. For example, semi-finished products of the same material manufactured on different manufacturing dates are assigned individual lot numbers for each manufacturing date and are managed separately by grouping.

For example, the semi-finished product production lots A001 and A002 and the semi-finished product production lots B001 to B003 in FIG. 16 are made of the same material, but the production locations are different. Further, the semi-finished product manufacturing lots A001 and A002 have different manufacturing dates and times, and the semi-finished manufacturing lots B001 to B003 have different manufacturing dates and times, for example.

The “order quantity” in FIG. 16 represents the quantity of the ordered product type ordered. In other words, "order quantity" means the total number of semi-finished products required to manufacture a variety of the ordered product. For example, the total number of semi-finished product production lots required for the ordered product product type J001 is "4".

In the appropriation process by the automatic calculation processing unit 1531 of the present embodiment, the total number of appropriations in the production lot of each semi-finished product for the product type of the specific 1 ordered product is less than the order quantity of the ordered product type. Will be treated as a valid allocation combination solution. This is because, as a practical matter, even if the inventory quantity of one of the semi-finished product production lots is insufficient to meet the order quantity required for the ordered product type, the inventory of the semi-finished product production lot is delivered. This is because, as soon as it is done, it is possible to take measures to cover the shortage of the semi-finished product.

On the other hand, if the total number of allocations of the production lots of each semi-finished product exceeds the order quantity for the product type of the ordered product, it is determined that the total allocation number constraint condition is not satisfied, and the surplus amount is determined by the subsequent first allocation number correction step. By subtracting the allocation number of, the total allocation number of the semi-finished production lot is adjusted so that it does not exceed the order quantity. The reason for making such adjustments is that it is not necessary to secure an appropriate number in the production lot of semi-finished products, which is larger than the ordered quantity required for the product type of the ordered product.

The “inventory quantity” in FIG. 16 is the inventory quantity of the semi-finished product production lot. For example, the number of semi-finished products in the semi-finished product production lot A001 is "12", which means that a maximum of 12 can be allocated.

In FIG. 16, an appropriation combination solution of a combination of five types of ordered products and five types of semi-finished product production lots is shown. However, the number of types of ordered products and the number of types of semi-finished product production lots allocated to each ordered product type are not limited to five. It is possible to arbitrarily set the types of ordered products of L (L is an integer of 2 or more) types. In addition, the number of types of semi-finished product production lots allocated to each ordered product type is M (M is M) unless there is a restriction on the upper limit of the semi-finished product production lot type for the ordered product type. It is possible to allocate a production lot of any semi-finished product of (natural number) or more types. Hereinafter, each step shown in FIG. 15 will be described in detail with reference to a specific example.

In step S1 (setting of the initial solution), the initial solution setting unit 42 sets the number of allocations of the production lot of each semi-finished product to be allocated to the product type of each ordered product as the initial solution of the allocation combination solution. As this initial solution, the number of all semi-finished product production lots to be applied to all the ordered product types may be set to 0, an arbitrary natural number, or a pseudo random number. May be set at random.

In general, the solution space of an allocation combination solution often includes a multimodal distribution having a plurality of maximum values, rather than a case where one maximum value is the optimum solution. Therefore, from the viewpoint of suppressing local bias in the initial solution, as the initial solution of the allocation combination solution, the allocation number in the production lot of all semi-finished products to be allocated to all the ordered product types should be set to the same number. Is preferable. Further, from the viewpoint of setting the initial solution so that various constraints are satisfied, it is preferable to set the number of allocations of the production lots of each semi-finished product to 0 for all the ordered product types.

FIG. 17 is a diagram showing an allocation combination solution when the allocation number in the production lot of all semi-finished products for all the ordered product types is set to 0. In step S1, the initial solution setting unit 42 sets the initial solution as shown in FIG. 17, for example.

In step S2 (setting the number of loops), the counter unit 43 sets the value of the counter C, which represents the number of times the allocation combination solution is rewritten, to 0. The value of the counter C means the number of times the allocation number is rewritten from the initial solution of the allocation combination solution. However, at the stage of step S2, the allocation number has never been rewritten with respect to the initial solution of the allocation combination solution. Therefore, in step S2, the counter unit 43 sets the value of the counter C to 0.

In step S3 (loop determination), the counter value determination unit 44 compares the value of the counter C with the loop number setting value N, and determines whether or not the value of the counter C is equal to the loop number setting value N. When the value of the counter C is equal to the loop number setting value N (YES in step S3), the counter value determination unit 44 determines that the currently set allocation combination solution is the best solution, and the process of FIG. 15 ends. On the other hand, when the value of the counter C is not equal to the loop number setting value N (NO in step S3), the counter unit 43 increments the value of the counter C by "1" in step S4.

In step S5 (change of a specific allocation number), the allocation number changing unit 45 creates a provisional allocation combination solution in which the allocation number of the production lot of any one type of semi-finished product is changed in the allocation combination solution.

FIG. 18 is a diagram schematically showing an example of the allocation combination solution before the change. FIG. 19 is a diagram schematically showing an example of the modified allocation combination solution. For example, when the allocation combination solution is the one shown in FIG. 18, the provisional allocation combination solution created by the allocation number changing unit 45 is the manufacture of any one semi-finished product with respect to the allocation combination solution shown in FIG. The lot allocation number has been changed, for example, as shown in FIG.

The number of semi-finished product production lots A002 allocated to the ordered product product type J002 is "0" in FIG. 18, but is changed to "2" in FIG. In the provisional allocation combination solution of FIGS. 18 and 19, the production lot of the specific 1 semi-finished product for the product type of the specific 1 ordered product to be processed is shaded. In the drawings below, the processing target is clearly indicated by shading. The "upper limit of the number of lots" in FIGS. 18 and 19 will be described later in step S6.

Here, in the provisional allocation combination solution, the method of selecting the production lot of a specific one semi-finished product whose allocation number is changed is not particularly limited. For example, the production lot A001 (the number of allocations in the upper left corner of FIG. 18) of the specific 1 semi-finished product of the specific 1 ordered product product type J001 may be selected. Alternatively, randomly select any one ordered product type from all the ordered product types, and randomly select from all semi-finished product production lots that can be applied to the selected ordered product type. You may select any one semi-finished product production lot.

Further, the changed allocation number (for example, "2" in FIG. 19) is arbitrary from an integer of 0 or more up to the smaller of the order quantity of the ordered product type and the inventory quantity of the semi-finished production lot. Can be selected for. That is, when changing the allocation number of the semi-finished product production lot A002 of the ordered product type J002 shown in FIG. 18, the order quantity “3” of the ordered product type J002 and the inventory quantity “18” of the semi-finished product manufacturing lot The upper limit is "3", which is the smaller of the above, and the appropriate number after the change can be randomly set within the range of 0 to 3. Therefore, in FIG. 19, the allocated number after the change is set to “2”.

When step S5 is executed a plurality of times while repeating the loops of steps S3 to S13 in FIG. 15, if either one or both of the ordered product type or the semi-finished product production lot to be changed is different for each step S5. It is preferable to tighten. For example, assuming that the product type J001 of the ordered product is constant, a provisional allocation combination solution is set in which the allocation numbers of the semi-finished product production lots A001, A002, B001, B002, and B003 are changed in this order, and when that is completed, the product type J002 of the ordered product is set. It is preferable to repeat step S5 a plurality of times, such as changing and executing the same operation. Of course, for each step S5, the product combination of the ordered product type and the semi-finished product production lot to be changed may be randomly set.

Step S5 is preferably performed for the product combinations of all semi-finished production lots for all the ordered product varieties in the allocation combination solution. For example, in the case of the allocation combination solution shown in FIG. 19, step S5 is performed once for each of the 25 allocations, which are all product combinations of the production lots of the five semi-finished products for the five types of ordered products. It is preferable that the above is executed and the allocation number is changed.

The execution order of step S5 (change order of the allocated number) is not limited to a specific order. In step S5, for example, the allocation number one by one below the allocation number in the upper left corner of the allocation combination solution shown in FIG. 19 (the allocation number of the semi-finished product production lot A001 with respect to the product type J001 of the ordered product) (that is, the allocated number of the ordered product). The production lot of the semi-finished product A002, B001, B002, B003 for the product type J001 may be changed, and then the allocation number of the production lot of each semi-finished product to the product type J002 of the ordered product may be changed. .. Alternatively, step S5 is executed by randomly selecting one from 25 combinations of production lots of each semi-finished product for each ordered product variety in the allocation combination solution of FIG. 19, and each ordered product variety. Step S5 may be executed one or more times for each of the allocation numbers of the production lots of each semi-finished product.

In step S6 (determination of satisfaction of lot number constraint condition), the lot number determination unit 46 determines whether or not the provisional allocation combination solution satisfies the lot number constraint condition. The lot number constraint is a non-linear constraint to meet the needs of the product varieties of the ordered product, and specifically, the upper limit of the number of types of semi-finished production lots to be applied to the product varieties of one ordered product. It is a constraint. For example, the upper limit of the number of types of semi-finished product production lots to be applied to the ordered product type J002 in FIG. 19 is "2". Therefore, as for the number of types of semi-finished products to be applied to the ordered product type J002, two or less semi-finished product manufacturing lots must be selected from the five semi-finished product manufacturing lots A001 to A002 and B001 to B003. Instead, the number of allocations must be set in the production lot of the selected semi-finished product.

When the lot number determination unit 46 determines that the number of types of ordered products for which the number of allocations has been changed in the provisional allocation combination solution exceeds the upper limit of the number of types of semi-finished product production lots allocated to the types of ordered products (step). NO in S6), the process proceeds to step S7. On the other hand, the lot number determination unit 46 determines that the number of types of ordered product types for which the number of allocations has been changed in the provisional allocation combination solution is equal to or less than the upper limit of the number of types of semi-finished product production lots allocated to the ordered product types. Then (YES in step S6), the process proceeds to step S8.

In the case of the provisional allocation combination solution shown in FIG. 19, by changing the allocation number of the semi-finished product production lot A002 to the ordered product product type J002 in step S5, the semi-finished product production lot allocated to the ordered product type J002 is increased. There are three types of semi-finished product production lots A001, A002 and B002. For this reason, the upper limit of the number of types of semi-finished product production lots to be allocated to the ordered product type J002 exceeds the upper limit "2". Therefore, in the case of the specific example shown in FIG. 19, NO is determined in step S6, and the process proceeds to step S7.

In step S7 (lot number correction step), the lot number correction unit 47 sets the allocation number of the production lots of the semi-finished products other than the semi-finished product production lot of the changed product type of the ordered product whose allocation number is changed to 0. Explaining with a specific example of the provisional allocation combination solution shown in FIG. 19, the lot number correction unit 47 of the semi-finished products among the production lots A001, A002 and B002 of the three semi-finished products allocated to the ordered product product type J002. Set the allocation number of either one of the production lots A001 or B002 of the semi-finished products other than the production lot A002 to 0.

FIG. 20 is a diagram showing a provisional allocation combination solution when the lot number correction unit 47 corrects the allocation number of the semi-finished production lot B002 to “0” with respect to the provisional allocation combination solution of FIG. As a result, the number of types of semi-finished product production lots allocated to the ordered product type J002 can be corrected so as not to exceed the lot upper limit number of the ordered product type J002, and the provisional allocation combination solution is a constraint on the number of lots. The tentative allocation combination solution can be modified to satisfy.

In step S8 (satisfaction determination of the total allocation number constraint condition), the allocation number determination unit 48 determines whether or not the provisional allocation combination solution satisfies the total allocation number constraint condition. The total allocation number constraint condition is a constraint on the upper limit of the total allocation number of the semi-finished product production lots to be allocated to the product type of the ordered product including the semi-product production lot of the allocation number changed in step S5. The upper limit of the total allocation number of semi-finished product production lots is the order quantity of the ordered product types. For example, in FIG. 20, the order quantity of the ordered product product type J002 is “3”. Therefore, it is necessary to set the total allocation number of the production lots A001 to A002 and B001 to B003 of the five types of semi-finished products to "3" or less.

When the allocation number determination unit 48, in the provisional allocation combination solution, the total allocation number of the production lots of all the semi-finished products to be allocated to the product type of the ordered product whose allocation number is changed exceeds the order quantity of the product type of the ordered product. If it is determined (NO in step S8), the process proceeds to step S9. On the other hand, in the provisional allocation combination solution, the allocation number determination unit 48 totals the allocation numbers of the production lots of all the semi-finished products to be allocated to the product types of the ordered products whose allocation numbers are changed, which is equal to or less than the order quantity of the ordered product products. If it is determined that (YES in step S8), the process proceeds to step S10.

In the case of the provisional allocation combination solution shown in FIG. 20, the total allocation number of the production lots of the semi-finished products allocated to the ordered product product type J002 with the allocation number changed is “4”. For this reason, it exceeds the upper limit of the total number of semi-finished product production lots to be allocated to the ordered product type J002, that is, the order quantity "3" of the ordered product type J002. Therefore, in the case of the specific example shown in FIG. 20, the appropriation number determination unit 48 determines NO in step S8, and the process proceeds to step S9.

In step S9 (first allocation number correction step), the first allocation number correction unit 49 is a value obtained by subtracting the order quantity of the order product type from the total allocation number of the order product types whose allocation number has been changed. From the number of semi-finished product production lots other than the semi-finished product production lot for which the allocation number has been changed, out of all the semi-finished product production lots that are allocated to the product types of the ordered products by setting an arbitrary natural number up to The allocation number obtained by subtracting the natural number is set as the new allocation number.

Explaining with a specific example of the provisional allocation combination solution shown in FIG. 20, the first allocation number correction unit 49 starts with the total allocation number “4” of the semi-finished product production lots A001 and A002 allocated to the ordered product product type J002. The natural number "1" obtained by subtracting the order quantity "3" of the ordered product type J002 is set. Then, the first allocation number correction unit 49 includes the production lots of the semi-finished products other than the semi-finished product production lots A002 of which the allocation number is changed among all the semi-finished product production lots A001 and A002 allocated to the ordered product type J002. (In FIG. 20, the production lot A001 of the semi-finished product) is set by subtracting the natural number “1” from the allocation number “2” as the new allocation number “1”.

FIG. 21 is a diagram showing a provisional allocation combination solution after modification by the first allocation number correction unit 49. The number of semi-finished product production lots A001 allocated to the ordered product product type J002 is changed from "2" in FIG. 20 to "1" in FIG. 21.

By executing step S9, the number of allocations of the provisional allocation combination solution is corrected so that the total number of allocations of the semi-finished production lots allocated to the ordered product type J002 does not exceed the ordered quantity of the ordered product type J002. can do. When step S9 is completed, the process returns to step S8.

In the provisional allocation combination solution shown in FIG. 20, it was explained that the total allocation number constraint condition can be satisfied by one modification by subtracting "1" from the allocation number of the semi-finished product production lot A001. .. However, it is possible that the total allocation number constraint condition cannot be satisfied by one modification in this way, and the provisional allocation combination solution after step S9 is executed once does not satisfy the total allocation number constraint condition. In this case, the automatic calculation processing unit 1531 repeats steps S8 and S9 until a provisional allocation combination solution that satisfies the total allocation number constraint condition is obtained. As a result, it is possible to correct the allocation number of a plurality of semi-finished product production lots other than the semi-finished product production lot whose allocation number is changed, and it is possible to prevent the semi-product production lot for which the allocation number is modified to be biased. it can.

In step S10 (inventory quantity constraint condition satisfaction determination), the inventory quantity determination unit 50 determines whether or not the provisional allocation combination solution satisfies the inventory quantity constraint condition. The inventory quantity constraint condition is a constraint based on the inventory quantity of the production lot of the semi-finished product whose allocation number is changed in step S5. For example, in FIG. 21, the inventory quantity of the production lot A002 of the semi-finished product having the allocated number changed in step S5 is “18”. Therefore, it is necessary to make the total number of appropriations of the semi-finished product production lot A002 to be allocated to all the ordered product types J001 to J005 to "18" or less.

The inventory quantity determination unit 50 determines the total inventory quantity of the production lots of the semi-finished products whose allocation numbers are changed in step 5 for all the ordered product types in the provisional allocation combination solution. If it is determined that the value is exceeded (NO in step S10), the process proceeds to step S11. On the other hand, the inventory quantity determination unit 50 determines the total number of allocations of the production lots of the semi-finished products whose allocation numbers are changed in step S5 for all the product types of the ordered products in the provisional allocation combination solution. If it is determined that the quantity is less than or equal to the quantity (YES in step S10), the process proceeds to step S12.

In the case of the provisional allocation combination solution shown in FIG. 21, the total allocation number (2 + 2 + 16 = 20) of the semi-finished product production lot A002 whose allocation number is changed in step S5 is half for all the ordered product varieties J001 to J005. The inventory quantity "18" of the production lot A002 of the product is exceeded. Therefore, in the case of the specific example shown in FIG. 21, the inventory quantity determination unit 50 determines NO in step S10, and the process proceeds to step S11.

In step S11 (second allocation number correction step), the second allocation number correction unit 51 calculates the inventory quantity of the production lot of the semi-finished product from the total allocation number of the production lots of the semi-finished products whose allocation numbers are changed in step S5. Set an arbitrary natural number up to the value obtained by subtraction. The second allocation number correction unit 51 sets the allocation number obtained by subtracting the natural number from the allocation number of the production lot of the semi-finished product other than the production lot of the semi-finished product whose allocation number is changed in step S5 as the new allocation number.

Explaining with a specific example of the provisional allocation combination solution shown in FIG. 21, the second allocation number correction unit 51 starts from the total allocation number “20” of the semi-finished product production lot A002 whose allocation number is changed in step S5. A natural number (for example, 2 in this embodiment) is set up to a value "2" obtained by subtracting the inventory quantity "18" of the product manufacturing lot A002. Then, the second allocation number correction unit 51 changes the allocation number in step S5 in the provisional allocation combination solution from the allocation number "16" of the ordered product type J005 other than the allocation number of the semi-finished product production lot A002 to the natural number "16". The allocation number "14" obtained by subtracting "2" is set as the new allocation number.

FIG. 22 is a diagram showing a provisional allocation combination solution after modification by the second allocation number correction unit 51. The allocation number of the semi-finished product production lot A002 to the ordered product product type J005 is changed from "16" in FIG. 21 to "14" in FIG. 22.

By executing step S11, the allocation number of the provisional allocation combination solution can be corrected so that the total allocation number of the semi-finished product production lot A002 does not exceed the inventory quantity of the semi-finished production lot A002. When step S11 is completed, the process returns to step S10.

In the provisional allocation combination solution shown in FIG. 22, the inventory quantity constraint condition can be satisfied with one modification by subtracting "2" from the allocation number of the semi-finished product production lot A002 with respect to the ordered product product type J005. The case was explained. However, it is possible that the inventory quantity constraint condition cannot be satisfied by one modification as described above, and the inventory quantity constraint condition may not be satisfied even by the provisional allocation combination solution after step S11 is executed once. In this case, the automatic calculation processing unit 1531 repeats steps S10 and S11 until a provisional allocation combination solution that satisfies the inventory quantity constraint condition is obtained. As a result, it is possible to correct the number of allocations of a plurality of semi-finished product production lots other than the semi-finished product production lots for which the allocation number has been changed, and it is possible to prevent the semi-product production lots for which the allocation number is modified from being biased. ..

In step S12 (comparison of evaluation values), the evaluation value comparison unit 52 determines the evaluation value A of the allocation combination solution before executing step S5 and YES in step S10 based on the predetermined evaluation function. The evaluation value B of the tentative allocation combination solution of is calculated. The evaluation values A and B are both specified by specific numerical values, and the higher the numerical value, the closer to the optimum solution. As the evaluation function for calculating the evaluation values A and B, it is preferable to use the evaluation function F of the following formula (I).

Here, _{pi and j} in the above formula (I) are M used for producing the product type i of one specific order-made product among the product types of L (L is an integer of 2 or more) types. (M is a natural number) It is a parameter that defines the priority to be allocated to the production lot j of a specific one semi-finished product among the production lots of the kind of semi-finished products, and _{ai and j} are the ordered products of the specific one. It is the allocation number of the production lot j of the specific 1 semi-finished product allocated to produce the variety i of the above.

The above priority depends on the conditions related to the type of each ordered product (for example, required performance, specifications, applications, size, etc.) and the conditions related to the production lot of each semi-finished product (quality, raw materials, expiration date, application, shape, etc.). It is a specified parameter. For the above priority, for example, the first priority is set by a 10-point evaluation of 1 to 10 points based on the conditions related to the type of the ordered product, and the 10-point evaluation of 1 to 10 points is set based on the conditions related to the production lot of the semi-finished product. By setting the second priority with, and simply adding the first priority and the second priority, it is possible to set the priority of the production lot of each semi-finished product for each ordered product type.

FIG. 23 is a diagram showing numerical examples of priorities of the semi-finished product production lots A001 to A002 and B001 to B003 to be allocated to the ordered product varieties J001 to J005.

Regarding the priority of FIG. 23, the priority tends to be higher for the ordered product type and the semi-finished product production lot, which have a restriction that it is difficult to allocate the semi-finished product production lot to the ordered product type. This is because the inventory of semi-finished product production lots can be reduced by allocating earlier for the types of ordered products and semi-finished product production lots, which have more restrictions in terms of inventory management.

The evaluation value A is obtained, for example, by integrating the allocation numbers _{ai and j} in the allocation combination solution shown in FIG. 18 and the priority _pi and _j shown in FIG. 23 and calculating the total sum. be able to. The evaluation value B is calculated by summing up the allocation numbers _{ai and j} in the provisional allocation combination solution shown in FIG. 22 and the priority _pi and _j shown in FIG. 23, for example. Obtainable.

When the evaluation value comparison unit 52 compares the evaluation value A of the allocation combination solution with the evaluation value B of the provisional allocation combination solution and determines that the evaluation value B is less than the evaluation value A (NO in step S12), The allocation combination solution is not changed, and the process returns to step S3. On the other hand, when the evaluation value comparison unit 52 determines that the evaluation value B is equal to or higher than the evaluation value A (YES in step S12), the process proceeds to step S13. Then, in step S13, the allocation combination update unit 53 rewrites the provisional allocation combination solution to a new allocation combination solution.

By rewriting the allocation combination solution in this way, the allocation number of the production lot of each semi-finished product for each ordered product type in the allocation combination solution can be brought close to the optimum solution. When step S13 is completed, the process returns to step S3. As described above, each step of step S3 to step S13 is repeated. Then, in step S3, when the counter value determination unit 44 determines that the value of the counter C is equal to the loop number setting value N (YES in step S3), the process of FIG. 15 ends.

(effect)
As described above, in the present embodiment, the diversion condition storage unit 143 determines that the combination of the material code 401 of the semi-finished product and the material code 402 of the ordered product is "applicable" or "applicable or not". The material code condition 400 including the appropriation determination 403 indicating "holding the determination of" is stored. Therefore, it is possible to expand the product combinations that are determined to be applicable even when the material code 401 of the semi-finished product and the material code 402 of the ordered product are different. Further, the diversion condition storage unit 143 determines that a semi-finished product having a quality rank higher than the quality rank 502 as the judgment specification value set in the product type 501 of the ordered product is "applicable" or "applicable". The quality rank condition 500 including the appropriation determination 503 of the higher rank indicating "holding the appropriation determination" is stored. Therefore, it is possible to expand the product combinations that are determined to be applicable even when the quality rank of the semi-finished product and the quality rank of the ordered product are different. Further, the diversion condition storage unit 143 stores the length condition 600 including the specified value 602, the applicable 603, and the determination hold 604, which are set for each product type 601 of the ordered product. Therefore, the product combinations determined to be applicable can be expanded not only to the range of the specified value 602 but also to the range of applicable 603. As a result, according to the present embodiment, it is possible to improve the determination of appropriation or not and appropriately support the appropriation work.

Further, in the present embodiment, with respect to the range in which the determination of appropriation is suspended, for example, a person in charge of a factory can determine the appropriation from a production management viewpoint or a technical viewpoint. Therefore, according to the present embodiment, it is possible to further improve the determination of appropriation / disapproval and appropriately support the appropriation work.

(2) In the above embodiment, with respect to the product combination represented by the symbol “Δ” (that is, the determination of appropriation is suspended), a priority may be set for the entity that determines whether or not appropriation is possible. ..

For example, the person in charge of the production control department may first determine whether or not to allocate the product from the viewpoint of process control, add the product combination determined to be applicable, and consider the optimum allocation combination.

Then, by adding product combinations that can be applied at the discretion of the production engineering department, it becomes possible to meet the delivery date of the ordered product, reduce the inventory quantity of semi-finished products to an appropriate level, and so on. If the quality of appropriation is improved, the person in charge of the production engineering department may add the product combination after judging whether or not the appropriation is possible from a technical point of view.

(3) In the above embodiment, with respect to the product combination represented by the symbol “Δ”, the entity that determines whether or not the product can be applied may be determined in advance for each determination specification type. For example, the product combination represented by the symbol "△" is represented by the product combination represented by the symbol "△ 1" and the product combination represented by the symbol "△ 2" (or by the red symbol "△"). It may be divided into a product combination and a product combination represented by the blue symbol “Δ” in advance.

For example, the product combination (first judgment entity group) represented by the symbol “Δ1” may be set in advance so that the person in charge of the production control department (first determination entity) determines whether or not the product can be applied. For example, the product combination (second judgment entity group) represented by the symbol “Δ2” may be set in advance so that the person in charge of the production engineering department (second determination entity) determines whether or not it can be applied. The diversion condition storage unit 143 may store a predetermined determination subject in association with the determination specification type.

(4) In the above embodiment, "material code", "quality rank", and "length" are used as the judgment specification type, but the present invention is not limited to these.

For example, a "semi-finished product type" that combines multiple judgment specification types such as "material code", "quality rank", and "length" is set, and in the past, it has been diverted and applied at the discretion of a person. The product combination of the "semi-finished product type" and the "ordered product type" may be stored in the diversion condition storage unit 143 as the diversion record information. The determination processing unit 152 may determine that the product combination of the "semi-finished product type" and the "ordered product type" stored as the diversion record information in the diversion condition storage unit 143 can be applied.

(5) In the quality rank condition 500 (FIG. 5) of the above embodiment, the production lot of a semi-finished product having a higher quality rank is set as a higher rank allocation determination 503 with respect to the quality rank 502 of the ordered product product type 501. "Appropriate" and "judgment pending" are set, but are not limited to this.

For example, a quality rank condition in which "applicable" and "judgment pending" are set for the product types of ordered products having lower quality ranks with respect to the quality ranks (for example, ranks QR1 to QR5) of semi-finished product production lots. May be used.

(6) The quality rank 204 (FIG. 2) of the above embodiment indicates the rank of the quality specification of the surface roughness, but the present invention is not limited to this. The quality rank may indicate, for example, the rank of the content ratio of impurities, and the quality rank may indicate the order of superiority or inferiority.

(7) In the above embodiment, "length" is used as the determination specification type, but the present invention is not limited to this. As the determination specification type, for example, "weight" may be used instead of or in addition to "length". That is, a determination specification type represented by a "numerical value" such as "length" and "weight" may be used.
