AS shown in fig. 3, the operation module 200 includes an MPS (Master Production Schedule, main production plan) operation module 210, an AP (AGGREGATE PLANNING, comprehensive plan) operation module 220, and an AS (Advanced Scheduling, advanced schedule) operation module 230. Wherein:

The MPS operation module 210 is configured to calculate a sub-plan product production requirement according to the sales order requirement and the product bin inventory number, and generate a main production plan, where the main production plan includes at least the product requirement number.

The production requirements of the sub-plan finished products can be daily-plan finished product production requirements, weekly-plan finished product production requirements, monthly-plan finished product production requirements and the like, and the sub-plan finished product production requirements can be flexibly set according to actual requirements in practical application.

Specifically, the number of product demands in the primary production plan = sales order demand-number of product warehouse inventory, the priority delivery of the preceding demand delivery date is satisfied.

In the embodiment of the present invention, MPS operation module 210 calculates, for example, the production requirement of the weekly plan product and generates the main plan according to the requirement of the sales order and the inventory number of the product bin. Priority scheduling is arranged according to the priority of delivery date, and delivery requirements are met.

The AP operation module 220 is configured to decompose and generate the production requirements of the sub-components of each process segment according to the number of product requirements in the main production plan and the corresponding BOM, work in process (i.e. work in process) of each process, semi-finished inventory, and semi-finished BOM, and generate a process production plan of each process segment and a material shortage and purchase plan of the raw and auxiliary materials.

Each process segment includes, for example, DP (DIE PREPARE, chip preparation), ASSY (Assembly), TMP (TEST MARK PACK, test marking package), and the like. According to the embodiment of the invention, according to the corresponding BOM, WIP production of each process, semi-finished product inventory and semi-finished product BOM, meanwhile, based on the quantity of finished product requirements in the main production plan, materials required for meeting the quantity of finished product requirements are decomposed and combined with the WIP production, the semi-finished product inventory and the like, and an unfinished process production plan is automatically generated.

The material shortage and purchase plans of the original auxiliary materials at least comprise material shortage information and a purchase demand plan, and the purchase demand plan at least comprises purchase demand quantity, purchase time, expected arrival time and the like. Specifically, the purchasing demand quantity=the production demand quantity-the stock quantity-the estimated warehouse-in quantity, the purchasing time is the current time, the estimated arrival time=the current time+the purchasing period, and the purchasing period can be set according to different materials respectively.

In the embodiment of the present invention, constraints such as productivity, mold, carrier, material, line replacement, and sleeve alignment are comprehensively considered during the operation of the AP operation module 220. Taking the processes of TMP and ASSY as an example, the final product demand quantity of TMP in the main production plan is calculated, and the material A is the semi-finished product of TMP.

The AP computing module 220 first calculates the production requirement of the material a according to the in-process WIP of each process of the TMP and the stock of the material a and the expected stock (referring to the number of planned output of the process of the ASSY process Duan Mo and the corresponding output time): production requirement of material A (namely, production requirement quantity of material A) =requirement quantity of material T-production prediction warehouse-TMP of each working procedure, namely, WIP-semi-finished product material A stock-prediction warehouse-semi-finished product material A;

It should be noted that the products of the TMP process are collectively referred to as T-stock, and that a-stock is a sub-component of T-stock at the BOM level.

And according to the BOM of the ASSY, according to the mode, namely according to the production demand quantity of the material A, combining the WIP production condition and the DP estimated warehouse entry condition to obtain the allowance demand to be produced and a side-by-side production plan, thereby obtaining the production demand of the DP and the demand of each raw material and auxiliary material R.

The R material is related to the A material only, and refers to the raw material required when the A material is run, wherein the R material is the raw material of a purchased part, and belongs to a sub-part of the A material in the BOM.

The AS operation module 230 is configured to calculate a production sub-plan of each process shop according to the process production plan of each process section; wherein, the production is arranged one by one according to the process sequence, and the production result of the previous process section is taken as the generation prediction and storage consideration of the next process section.

Wherein the production sub-plan of each process plant is related to the sub-plan product production requirements described above. For example, when the production demand of the sub-plan finished product is the production demand of the daily plan finished product, the corresponding production sub-plan of each process workshop can be the production time plan of each process workshop, and for example, when the production demand of the sub-plan finished product is the production demand of the weekly plan finished product, the corresponding production sub-plan of each process workshop can be the production daily plan of each process workshop; and when the production requirement of the sub-plan finished product is the production requirement of the month plan finished product, the corresponding production sub-plan of each process workshop can be the production week plan of each process workshop.

The AS operation module 230 comprehensively considers constraints such AS BOM, equipment capacity, mold, carrier, line changing, sleeve alignment, stop plan, on-production, etc., and calculates production sub-plans of each process plant based on the process production plan of each process segment generated by the AP operation module 220. For example, the AS operation module 230 calculates the production day plan of each process shop based on the process production plan of each process stage of DP, ASSY, TMP generated by the AP operation module 220, and schedules the production of the previous process stage one by one according to the process sequence ws→dp→assy→tmp, wherein the production result of the previous process stage is taken AS the production prediction and warehousing consideration of the next process stage, i.e. the production plan of each semi-finished product is taken AS the prediction and warehousing consideration of the next process stage. Wherein the production day schedule of each process plant is specific to the production products and sub-processes of each facility.

As shown in FIG. 4, the results export module 300 includes a procurement module 310 and a production management module 320.

Wherein:

the purchasing module 310 is configured to derive a material shortage and purchasing plan of the raw and auxiliary materials generated by the AP operation module 220.

Wherein the material shortage and purchase plans of the raw and auxiliary materials at least comprise material shortage information and purchase demand plans. In practical application, the purchasing module 310 can learn which material is about to be in the material shortage plan according to the operation result of the AP operation module 220, and for the material shortage plan about to be in the material shortage plan, the purchasing operation flow can be started in advance, so that the purchasing module 310 can timely derive the material shortage information and the purchasing demand plan. Wherein the deriving means may include sending the starved information and the purchasing demand plan to the purchasing member in the form of a mailbox.

Further preferably, the purchasing module 310 in the embodiment of the present invention is further configured to integrate the arrival schedule in the SAP and MES, and consider the arrival schedule as the estimated warehouse entry at the time of scheduling.

It should be noted that, the arrival schedule in SAP and MES refers to the arrival schedule of purchase, including the type, category, quantity and arrival time of materials, and in practical application, the production schedule may be executed according to the arrival condition of materials.

It is to be understood that, the purchasing module 310 in the embodiment of the present invention mainly includes two functions of purchasing in-transit and purchasing demand planning, where the purchasing in-transit function refers to integrating the arrival plan in the SAP and MES, and is considered as estimated warehouse entry during scheduling; the purchase demand planning function refers to deriving the operation result (the shortage information and the purchase demand plan) of the AP operation module 220.

The production management module 320 is configured to backfill the production report results fed back by the manufacturing execution system MES to the corresponding production plan according to the association relationship between the production work order and the plan demand from which the production work order originates, and when the next operation is performed, the backfilled production report warehouse quantity will reduce the corresponding production estimated warehouse quantity.

In the embodiment of the present invention, the production management module 320 includes a production work order, a report, and the like. The production job ticket can be generated by pushing down the sub-process production plan generated by the AS operation module 230 AS an executable production job ticket of the MES; and reporting the work and warehousing, and feeding back the execution completion condition of each planning task through integrating the completion list of the MES.

Specifically, in the embodiment of the invention, the SAP and the MES execute the production work order in a delivery workshop, and the execution condition of the plan is fed back through the report result of the MES. The production management module 320 integrates the report results fed back by the MES into the report intermediate table in the APS automatic scheduling system through the association relation between the production work order and the plan demand from which the production work order is derived, and backfills the corresponding production plan according to the report results, and when the next operation is performed, the backfilled report warehouse quantity can eliminate the corresponding production predicted warehouse quantity, so that rolling scheduling at any time is realized, and the production plan is adjusted.

For example, in practical application, the APS producer sends out a production task to the MES, and after receiving the production task sent by the APS, the MES executes corresponding production according to a single sheet, and automatically reports the production result to the APS, as shown in table 2.

TABLE 2

System module	Product(s)	Quantity of	Time to finish
				APS production work order	Product A	2000	2/10/2024
MES report results	Product A	1800	2/9/2024
