The mold name includes the name of the tool that can be used to produce the corresponding part, e.g., the mold name includes a left side wall, a right side wall, each mold corresponding to a mold number that is used to uniquely identify the corresponding mold. The shipment plan includes the shipment number of various types of parts, and for example, the shipment plan may include the shipment amount of the left side wall panel at 7 months 6 to 7 months 8 days, and the like.

The preset production period can be consistent with the delivery period in the delivery plan, and the preset production period can be customized by a user. The time units may include days/hour/half hour, etc., and the time units may be set according to specific needs. The production scheduling information comprises the production scheduling number of various parts. For example, the first production schedule includes 16 production quantities of the left side gusset outer panel on 6 days of 7 months, 20 production quantities on 7 days of 7 months, and so on. The warehouse-out plan includes the shipment volume of 7 months 6 days to 7 months 8 days, the preset production period can be 7 months 6 days to 7 months 8 days, and the parts can include a left side wall outer plate, a left front door inner plate and the like.

As shown in fig. 10, fig. 10 shows a display interface of a production target, and fig. 10 shows target 1: presetting production time length and target 2: number of die changes. According to the embodiment, the production scheduling target is directly displayed in a text form, so that a user can intuitively obtain the production scheduling target. In another embodiment, on the display interface of the scheduling targets, the electronic device displays controls for the user to add or delete any one of the scheduling targets. According to the embodiment, the target does not need to be modified in the return code program, and the updating convenience of the scheduling target is improved.

The scheduling score is used to quantify the scheduling efficiency, and may be calculated using a scoring function, which may be determined based on a weighted sum function of scoring terms.

In at least one embodiment of the application, when a new second production plan is obtained, the electronic device calculates a scheduling score for the new second production plan using a scoring function, and compares the scheduling score for the new second production plan to the scheduling score for the currently optimal second production plan. If the scheduling score of the new second production plan is smaller than the scheduling score of the current optimal second production plan, the electronic device updates the current optimal second production plan based on the new second production plan. If the production scores of all the second production plans are compared, the electronic equipment determines the currently optimal second production plan as a third production plan.

The determination process of the third production plan will be described with reference to fig. 11, and upon detecting that the user inputs a demand document (the demand document includes production data and a delivery plan), the electronic device invokes the production algorithm to analyze the production data and the delivery plan, resulting in the first production plan. In another embodiment, the electronic device receives the number of days of production, invokes the production scheduling algorithm to determine a preset production cycle based on the delivery plan and the number of days of production, and invokes the production scheduling algorithm to analyze the preset production cycle and the production data to obtain the first production plan. For example, the number of left side wall boards corresponding to 7 months and 6 days is 1000, the number of left side wall boards corresponding to 7 months and 7 days is 918, the number of left side wall boards corresponding to 7 months and 8 days is 922, and the number of left side wall boards corresponding to 7 months and 8 days is 3 days, and the determined preset production period can be from 7 months and 6 days to 8 months. According to the embodiment, the preset production period can be flexibly set by combining the delivery plan and the delivery days, and the delivery time does not need to be manually input, so that the output efficiency of the first production plan is improved. And the electronic equipment calls an adjustment algorithm to adjust the first production plan to obtain a second production plan, determines the production grading of the second production plan by using a grading function, and determines the second production plan with the lowest production grading as a third production plan. The scoring function can be determined based on the scheduling target, and the scheduling target can be preset, so that the user does not need to reset the scheduling target every time the user performs scheduling, and the simplicity of the user operation is improved. In addition, the scheduling targets can be updated based on different production environments, so that expansibility is improved.

In another embodiment, the electronic device may further iteratively adjust the first production plan based on the preset condition to obtain the third production plan. The preset conditions include optimal scheduling scores and/or preset iteration times, the preset iteration times can be determined according to actual production, for example, the preset iteration times can be set to 100 times. In this embodiment, the first production plan is determined first, and then the first production plan is iteratively adjusted, so that the iterative computation amount can be reduced, and the determination efficiency of the third production plan is improved.

In the embodiments of the present application, the first production plan may be determined by the production data and the delivery plan, and then the first production plan may be finely tuned, and then the third production plan may be screened from the second production plan by the production score, so that a large amount of computation due to iteration may be reduced, thereby improving the determination efficiency of the third production plan.

As shown in fig. 3, a flowchart of obtaining a first production plan according to an embodiment of the present application, as shown in fig. 3, specifically includes the following steps:

2011, for any type of parts, detecting whether the initial stock quantity is smaller than the sum of the preset stock lower limit quantity and the ex-stock quantity.

In at least one embodiment of the application, the electronic device detects, for any type of part, whether the initial inventory count is less than a sum of a preset lower inventory count and an out-of-stock count. If the initial inventory count is less than the sum of the preset lower inventory count and the outgoing inventory count, then step 2012 is performed; if the initial inventory count is greater than or equal to the sum of the preset lower inventory count and the outgoing inventory count, step 2013 is performed.

2012, Determining the production quantity of the corresponding type of parts based on the preset lower limit quantity of the stock, the initial stock quantity and the ex-stock quantity.

In at least one embodiment of the present application, the initial inventory count of the current time unit represents the inventory count of the parts before production, the initial inventory count of the next time unit is equal to the initial inventory count of the current time unit plus the production count of the current time unit minus the production count of the current time unit, for example, if the initial inventory count of the current time unit is 100, the production count of the current time unit is 200, the production count of the current time unit is 50, and according to the formula 100+200-50=250, the initial inventory count of the next time unit can be determined to be 250.

The electronic device determining the production quantity of the corresponding type of parts based on the preset lower limit quantity of the stock, the initial stock quantity and the ex-stock quantity comprises the following steps: calculating the sum of the preset lower limit quantity of the stock and the output quantity of each time unit in the preset production period as the minimum stock quantity of each time unit, and calculating the difference value between the minimum stock quantity of each time unit and the initial stock quantity of each time unit as the production quantity of each time unit.

For example, if the preset lower limit number of the left side wall outer panel is 30, the initial inventory number of 7 months 6 is 10, and the shipment number of 7 months 6 is 20, since the initial inventory number of 7 months 6 (10) < the preset lower limit number of the inventory (30) +the shipment number of 7 months 6 (20), the minimum inventory number of the left side wall outer panel at 7 months 6=the shipment number of 7 months 6 (20) +the preset lower limit number of the inventory (30) =50 are calculated, and the total production number of the left side wall outer panel at 7 months 6=the minimum inventory number of 7 months 6 (50) -the initial inventory number of 7 months 6 (10) =40 are calculated.

The method and the device can combine the determination of the preset lower limit quantity of the stock, the initial stock quantity and the delivery quantity to the production quantity, and can ensure that the stock quantity of the parts after delivery meets the requirement of the preset lower limit quantity of the stock, thereby being beneficial to coping with the requirement of large-batch ordering of customers.

2013, Determining the production scheduling number of the parts of the corresponding type based on the preset number.

In at least one embodiment of the present application, the preset number may be set to 0. For example, the preset lower stock limit number of the left side outer panel is 30, the initial stock number of 7 months and 8 days is 70, and the stock outgoing number of 7 months and 8 days is 20. The initial stock number of 7 months and 8 days (70) > the preset lower stock limit number (30) +the number of outgoing stocks of 7 months and 8 days (20), so that the left side outer panel is not produced at 7 months and 8 days when the production number of the left side outer panel at 7 months and 8 days is 0.

According to the embodiment of the application, under the condition that the initial inventory quantity is enough, the production quantity of the corresponding type of parts is set to be the preset quantity, so that the occupation of the parts with enough inventory quantity on the production line can be avoided, and the rationality of the first generation plan is improved.

As shown in fig. 12, a flowchart of a product scheduling method according to another embodiment of the present application includes the following steps:

1201, detecting whether the stock quantity of any part is larger than the preset stock upper limit quantity corresponding to any part based on the preset production time length.

Wherein, stock quantity of any part = total production quantity + initial stock quantity of any time unit-ex-stock quantity of any time unit.

In at least one embodiment of the present application, if it is determined that the inventory quantity of any part is greater than the preset upper inventory limit quantity corresponding to any part based on the preset production time length, step 1202 is performed; if it is determined that the stock quantity of any part is less than or equal to the preset stock upper limit quantity corresponding to any part based on the preset production time length, step 1203 is executed.

1202, Adjusting a preset production time period.

In at least one embodiment of the present application, the electronic device adjusting the preset production time period includes: the electronic equipment determines the upper limit number of the production of any part corresponding to each time unit in a preset production period according to the production data and the delivery plan of any part, obtains the production efficiency of the production line of any part on any part, determines the upper limit length of the production based on the ratio of the upper limit number of the production to the production efficiency, and adjusts the preset production time according to the upper limit length of the production.

In some embodiments, the electronic device determines the upper limit number of production runs from the initial inventory number, the out-of-stock number, and the preset upper limit number of inventory of any part, specifically, the upper limit number of production runs = the preset upper limit number of inventory-initial inventory number + out-of-stock number.

In some embodiments, if the upper production time period is less than the preset production time period, the preset production time period is updated based on the upper production time period. For example, if the production upper limit time is 7h and the preset production time is 8h, the preset production time is updated to 7h.

1203, The preset production time length is not adjusted.

According to the method and the device, the preset production time length is adjusted through the preset upper limit quantity of the stock, and the problem that enough space is not reserved due to the fact that parts produced in a certain time unit are too many can be avoided.

Fig. 13 is a flowchart of a method for product scheduling according to another embodiment of the present application, as shown in fig. 13, including steps 1301-1306:

1301, based on the production data and the delivery plan, a first production plan is obtained.

And 1302, adjusting the first production plan according to the production scheduling information and the production scheduling targets so as to advance the first production time to the second production time and obtain a plurality of second production plans.

For details of steps 1301-1302, reference is made to the detailed description of steps 201-202 above in FIG. 2, which is not repeated here.

1303, Responding to the update of the user to the scheduling target and the setting of the weight, and obtaining the updated scheduling target and the corresponding weight.

In at least one embodiment of the application, the display interface of the production target comprises a target update control, and the addition and deletion of the production target are realized based on the target update control. The display interface of the scheduling targets can also comprise weight setting controls, each scheduling target can be correspondingly provided with a weight setting control, when any scheduling target is deleted, the corresponding weight setting control is also deleted, when a new scheduling target is added on the display interface, the corresponding weight setting control is also newly added, and the weight of the corresponding scheduling target can be set through each weight setting control.

In another embodiment, the display interface of the scheduling targets is provided with a weight setting control, and the same setting of the weights of all the scheduling targets on the display interface can be realized through the weight setting control on the display interface.

1304, Obtaining a scoring item corresponding to the updated scheduling object as an updated scoring item.

In at least one embodiment of the application, the updated scoring items comprise the overtime period, the die changing times of the scheduling production line of various parts and the scheduling time difference value of the plurality of scheduling production lines. The overtime time represents a time length exceeding the normal working time, and the overtime time length can be determined based on a difference value between the production time length of the production line and the normal working time length. The number of die changes indicates the number of times the production line changes the die, and when the production line produces different types of parts, the die of the corresponding part type needs to be changed. The more the number of die changes, the shorter the time that the production line can be put into production. The difference value of the production time length of the production line is the difference value of the production time lengths of any two production lines, and the smaller the difference value of the production time length of the production line is, the more uniform the distribution time of the two corresponding production lines is.

1305, Determining a scoring function based on the updated scoring items and the corresponding weights, the scoring function being used to calculate a scheduling score for each second production plan.

In at least one embodiment of the application, the electronic device determines the scoring function using a weighted sum function based on the overtime period, the number of changes of modes, the difference in the scheduling period, and the corresponding weights.

The scoring function may include: energy = production_ overtime + abs (production_time) +10 (bad_time), where energy represents the scheduling score, production_ overtime represents the overtime length, production_time represents the scheduling length difference, and bad_time represents the abnormal time parameter. If the time unit is day, the corresponding unit time length is 24 hours, and when the production time length does not exceed the unit time length (for example, the production time length is 23 hours), the abnormal time parameter may be set to 0; when the production period exceeds the unit period (for example, the production period is 25 hours), the abnormal time parameter may be set to 1. By assigning the abnormal time parameter in this way, the scheduling score of the first production plan including the abnormal time can be made larger than the scheduling score of the first production plan not including the abnormal time, so that the third production plan is ensured not to include the abnormal time.

At 1306, a third production plan is determined based on the production scores for each of the second production plans.

For details of step 1306, reference is made to the detailed description of step 203 in FIG. 2 above, and the description is not repeated here.
