Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production / sales management system for managing production and sales of various articles.

[0002]

2. Description of the Related Art Conventionally, in each industry or individual company, when carrying out a normal corporate activity of manufacturing a unique product and selling the manufactured product, generally, a sales and sales department is in charge. , The extent to which a given product produced by the company can be sold or must be sold in a given period, such as a short-term, medium-term, or long-term period. The sales target and the appropriate inventory quantity that should be secured at all times are determined, and the result is used as sales plan information and the production department of the company is notified.

On the other hand, the production department which has received the information makes a production plan of the article on a daily, weekly, monthly, seasonal or yearly basis based on the sales plan information, that is, a daily plan. Short-term, medium-term, corresponding to sales plan, such as weekly plan, monthly plan, seasonal plan, or annual plan.
A long-term production plan will be drawn up and put into practice.

At that time, the sales department has a plurality of departments, and each department independently sells the same product and the same product type, and the essential parts of the product are almost the same. For example, each department produces products with some differences in shape, color, or accessories.
If they are sold individually, there is a risk that the sales plan will be complicated and the contents will not be unified.

On the other hand, the production department is often unfamiliar with the situation of the sales department, and therefore, it is almost the case that the production plan of the product concerned is made up entirely depending on the sales plan which has been contacted. Is. Therefore, for example, when a production factory has a plurality of production lines, or when factories manufacturing the same or similar products are dispersed in different regions, the same production type or alternative production can be used. Inefficient and inefficient operation of producing products of the same variety in different factories while it is more efficient to produce different types of products or to produce them in the same production plant. There were many dangers of going there.

[0006] Furthermore, since the communication between the sales department and the production department is insufficient, for example, if the inventory information is not accurately included in the sales plan, a plurality of sales of the same product are sold. There are departments, and in one department,
If a request is made to the production department to increase the production of the product due to the fact that the product is out of stock in a short period of time, the sales performance will not increase in another department and therefore the inventory will be planned. When the number exceeds the number, it may be possible to eliminate the extra production by accommodating the excess inventory to the departments that are out of inventory, but such information is clearly disclosed to a third party. If it is not done, extra production will be executed, and in the end, inventory will build up too much, resulting in higher selling costs.

[0007] In general, such a sales plan is made, and based on the sales plan, which production variety, at what time, including the allowance for raw materials, and at what factory and in what amount, what amount? It is extremely important to judge whether or not to manufacture, that is, to determine the optimum condition, that is, whether the manufacturing can be performed under the conditions of being efficient and minimizing the manufacturing cost. However, since it requires a lot of experience and judgment, not everyone can easily and quickly determine such sales and production plans. Therefore,
There is a problem that it takes time because it takes a considerable amount of time for a skilled person to create it.

In order to solve such a problem, in recent years, a computer has been introduced, and the work of the above-mentioned part requiring the knowledge of the expert has been put into practical use in the direction of mechanization and automation, but it is still complete. A complete production and sales management system has not been completed, and a considerable part, that is, a working part that requires the judgment and experience of a skilled person, is still in the existing state.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific examples of the production and sales management system according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a functional block diagram showing the basic configuration of the production and sales management system according to the present invention. In this figure, the production instruction information creating means 1 is means for producing the production instruction information by a predetermined calculation process based on the sales plan information, the ordering information, and the inventory information. The machine allocating means 2 has at least the production capacity (throughput) for each machine / product type prepared separately from the production instruction information.
It is a means for allocating a production instruction to each machine by a predetermined calculation process based on the production constraint condition information including. The scheduling means 3 is means for scheduling each machine by a predetermined arithmetic processing based on the output information from the machine allocation means 2. Then, in order to create rational production instruction information, the above-mentioned various means are internally provided.

FIG. 2 is a block diagram showing a hardware configuration of a production and sales management system according to an embodiment of the present invention. In this figure, reference numeral 11 is a CPU, reference numeral 12 is a main storage device, reference numeral 13 is an input device, reference numeral 14 is an output device,
Reference numeral 15 indicates an external storage device, and reference numeral 16 indicates a display device. Then, in such a hardware environment, each means in the above basic configuration is realized by running software as described below.

FIG. 3 is a block diagram showing the software configuration of the production and sales management system. As for the relationship between each means in the basic configuration and each subsystem in this figure, the production instruction information creating means 1 is the sales / production cooperation system 23, and the machine allocating means 2 is the total quantity adjusting system 2.
4. The scheduling means 3 corresponds to the advanced platforming system 25. Then, the processing procedure of the system is roughly as follows. First, the sales person in charge of sales planning system 21
The sales plan is entered in. Required data of the ordering information and the inventory information stored in the external storage device 15 is the sales system 22.
Extracted by. Based on the above information and, the production / production cooperation system 23 calculates the production instruction amount. The production instruction amount is adjusted to the producible amount by the total amount adjustment system 24, and the distribution machine is determined. In the advanced distribution system 25, the total amount adjustment system 24
Based on the results of "computer placement using artificial intelligence"
And the "dialogue placement by expert" determines the placement plan. Based on the distribution plan created by the advanced distribution system 25, the procurement plan for the materials and raw materials necessary for production, and the specific production work order plan, the work order material procurement system 2
Created by 6. Further, the distribution plan created by the advanced distribution system 25 is returned to the external storage device 15 as receipt information via the production progress grasping system 27. In this embodiment, by constructing the system as described above, a closed loop of input / output inventory information is formed between production and sales, and direct connection between sales information and production information is realized.

Next, a specific process for realizing the first production and sales management system according to the present invention will be described in detail. In the sales and production cooperation system 23, the latest warehousing date and the monthly production plan amount are calculated from the monthly sales plan entered by each sales person in the sales planning system 21. The monthly sales plan corresponds to the "sales position," which is the daily planned inventory amount calculated by "previous balance + planned warehousing-sales plan", as well as sales plan deviations, misconceptions, and warehousing deviations. Therefore, "minimum inventory", which is the amount of inventory that the person in charge of sales always wants to keep at a minimum, is included.

The procedure will be described with reference to FIG. In this embodiment, a production system in which a production instruction is issued once a month is assumed. Initial inventory of this month (a in Fig. 4) and planned storage amount of this month (b)
And the estimated inventory quantity (e) at the end of the current month based on the planned sales quantity (c + d) for the current month. Based on the estimated stock amount at the end of the month (e) and the daily planned sales amount for the following month, the first day when the stock amount becomes smaller than the specified minimum monthly stock amount (f) for the next month is the latest receipt date, that is, the next month production schedule. Set as the day. The next-month production scheduled date is determined based on the next-month production scheduled date and a predetermined production interval. A predetermined next-two-month minimum inventory amount (h) is obtained from the planned sales amount (h) from the planned production date of the next month to the planned production date of the next month, which is calculated from the planned sales amount of the next month for the day and the planned sales amount of the next month for the day. The planned inventory quantity (j) on the planned production day of the next month obtained in is subtracted from the quantity obtained by adding i) to determine the planned production quantity (k) of the next month. In this way, the planned production date and the planned production amount for the next month are determined.

Next, a specific process for realizing the second production and sales management system according to the present invention will be described in detail. In this case, the sales-production cooperation system 23 calculates the production instruction amount based on the 3-month sales plan data (delivery plan) and the end-of-month target inventory.

The procedure will be described with reference to FIG. In this embodiment, a production system in which a production instruction is issued once a month is assumed. Initial inventory for the month (a in Figure 5) and planned inventory for the month (b)
And the estimated inventory quantity (e) at the end of the current month based on the planned sales quantity (c + d) for the current month. Estimated inventory amount at the end of the month (e) and target inventory amount for the next month (f)
And the next month's production instruction amount (i) is determined based on the next month's planned sales amount (g + h). The next-month target inventory amount (f) and the next-two-month sales plan amount (j +
Based on k) and the next-second-month target inventory quantity (l), the next-second-month production instruction quantity (m) is determined. In addition, the planned production date of the next month, that is, the latest storage date is, for example,
It may be determined as a day on which the daily planned delivery quantity is less than the monthly reserve stock quantity (described later). In this way, the production instruction amount for the next month and the next two months is determined.

Next, a specific process for realizing the fourth production and sales management system according to the present invention will be described in detail. The advanced distribution system 25 creates a production plan for each product type based on the "production instruction" for each product type and section created by the sales and production cooperation system 23, and creates "receipt-based production plan" data. This storage-based production planning data is stored in the external storage device 1 as a "reception plan" by department / section and product type.
Stored in 5. Therefore, when data is sent from the advanced delivery system 25 to the external storage device 15, it is necessary to add department / section information to the receipt base production plan created by the advanced delivery system 25.

The procedure for one type of product will be described with reference to the specific example of FIG. First, in the sales and production cooperation system 23, department-by-section / daily production instruction data (A data in FIG. 6) is created. Based on the division / daily production instruction data (A data), the division / daily distribution rate (B data) is calculated. On the other hand, the advanced delivery system 25 creates daily receipt-based production plan data (C data). A function to adjust the difference between the receipt-based production plan (plan) and the daily production instruction (desired) based on the daily receipt-based production planning data (C data) and the department / day-specific production instruction data (A data) Storage schedule data (D data) is created based on (difference in schedule, difference in amount). The warehousing schedule data (D data) is apportioned by department / day by division / day apportionment rate (B data) to create warehousing scheduled data (E data) by department / section. In the present invention, the division / division proportional division ratio is not uniquely determined, and may be determined by an appropriate empirical method according to the situation of the division or the like. For example, if the production amount of the A part is 10 tons and the production amount of the B part is 5 tons, the proportioning ratios thereof are adjusted to the respective production amounts, and a method such as A part / B part = 10/5 is taken. Good.

Next, a specific process for realizing the third production and sales management system according to the present invention will be described in detail. This is to formulate a rational production plan in the advanced delivery system 25 by incorporating the mechanism for preventing the delivery delay and reducing the inventory described below into the production instruction data created by the sales and production cooperation system 23. It is possible. The basic idea is to configure the inventory plan value (month-end target inventory) in the sales plan as follows, as illustrated in FIG. 7. End-of-month target stock amount = basic stock amount + spare stock amount Basic stock amount = (basic end-of-month inventory month x planned shipping amount for the next month)
+ (Months of safety stock x planned delivery quantity for the next month)

The concept of basic inventory and spare inventory will be described. The total value of the basic month-end inventory months and the safety inventory months is called the basic inventory months, and the basic inventory amount is obtained by multiplying this by the planned delivery quantity for the next month. The basic monthly end-of-month inventory month is divided into several months in the monthly production plan, and the types of products to be produced are set in advance for each category so that the sales plan is not hindered. It is based on the idea of setting in advance the number of basic month-end inventory months that should be held as of the end of the current month. In addition, the number of months of safety stock represents the amount of stock that should be held as of the end of the current month so that the sales plan will not be hindered if the production time shifts. Further, the reserve inventory represents the minimum inventory quantity that the person in charge always wants to hold in order to cope with the fluctuation of the sales quantity. In this way, the balance between the production period and the target inventory at the end of the month is adjusted to prevent "ball exhaustion" and reduce inventory.

The relationship between the production instruction amount, the latest storage date and the spare stock is as follows. As long as the sales plan is executed almost as planned, the latest receipt date is the last day of the production category (for example, 15th, 25th).
Day, 5th of the following month). In reality, it is often the case that the appropriate stock at the end of the month has a “shake”. The production instruction amount is determined by correcting the production amount so that the next month's inventory becomes the month-end target inventory. Therefore, the tendency that the latest production date is concentrated toward the beginning of the month can be rearranged on a monthly basis for each basic production section, and as a result, the production side is not burdened.

Next, specific processing for realizing the fifth production and sales management system according to the present invention will be described in detail. In the present embodiment, the following technical structure makes it possible to manage the in-and-out inventory by department, section, and product type. First, in the warehousing series, based on the sales plan data (sales planning system 21) input for each person in charge,
Create production instruction data for each person in charge and type. At this time, based on the above-mentioned production instruction data, a table that associates the person in charge and the product type (product type sales person table) is created. When the department-by-product / by-product storage scheduled data and the data by department / product-by-product storage data are recorded in the system, the sales information for each product is used to add the responsible information and create a predetermined database. With the above configuration, the data of the receipt series is managed for each person in charge.

Further, in the delivery sequence, when an order is input, the department / section charge code is automatically set by the password of the input person. This department / section charge code is used to manage the data of the delivery series for each charge. Thus, in this embodiment,
All production and sales management data can be managed by ordering section, product type, and person in charge.

Although the basic concept of the embodiment of the present invention has been described above, it is easy for those skilled in the art to realize an actual system, that is, a program from this description. Of course, the present invention is not limited to this embodiment, and it will be easy for those skilled in the art to devise various embodiments.

Further, in the present invention, the concept of "department" refers to the whole unit of occupation, and should not be bound by the term "department". Also, "day"
The concept of "includes concepts such as" week "," season "," month ", etc. The point is that the concept includes all that can be grasped including" day ", whether it is direct or indirect. is there.

[0033]

As described above, according to the present invention,
In order to improve the above-mentioned drawbacks of the conventional technology, in particular, by improving the technology for creating production instruction information, we provide a production and sales management system that further streamlines and streamlines the system covering manufacturing, sales, and logistics. To be done.
