FIG. 7 is a chart showing schedule planning conditions for each process in one embodiment. As shown in FIG. 7, first, the production schedule of each product is obtained by (work-in-process quantity of next process)-(scheduled usage quantity) = scheduled production quantity. That is, for the product AR541 processed by the process A, since the in-process quantity of the next process is 150 and the planned usage quantity is 600, the planned production quantity is 600-1.
50 = 450. Similarly, the planned production amount of the product AR642 to be processed by the process A is 450, the total planned production amount of the process A is calculated to be 900, and the production capacity of the equipment is 1200 or less, so 900 is a producible quantity. is there. In this way, the planned production quantity is calculated for each of the processes A, B, and C, and the production quantity is calculated by comparing this with the production capacity of the equipment corresponding to each process.
That is, the quantity to be added to each process is determined.

For example, when determining the production amount of the process A, the minimum value of the shared facilities 12, 13, 14 is set as the maximum production amount, and the usage ratio of each process A related to the shared facility, that is, the ratio of the arranged amount is set. The quantity obtained by multiplication is compared with the minimum value of the intrinsic facility capacity of the process A, and the production quantity is determined from the smaller value. The processes B and C are also calculated by the same procedure, and the daily production amount for each process shown in FIG. 3 is determined.

工程の作業日を書き込み小日程計画とする。FIG. 4 is a flow chart showing a processing procedure for producing a production plan according to an embodiment by the editing apparatus 7 of FIG.
A processing procedure for producing a production plan based on the determination of the schedule planning condition will be described with reference to FIG. S01: Allocate arrangement information and product engineering information. S02: Determine the result of allocation. If there is no or insufficient chemical engineering information, the ordering information is excluded as an error, a ordering information file as shown in FIG. 6 is created, and the production content is instructed. S03: The arrangement information is extracted and separated for each process. S04: As shown in FIG. 5A, the processes are sorted for each process in order of the delivery date, and the items with the imminent delivery date can be preferentially input. S05: The quantity determined by the schedule planning condition file, that is, (planned number of days × process production quantity / day), is cut out for 3 days, for example. S06: As shown in FIG. 5 (b), the cut-out contents are rearranged and grouped according to the processing conditions I, II, and III such as thickness and material. S07: The production amount for one day is cut out from the arrangement information for each process and accumulated on the first day, the second day, and so on. S08: As shown in FIG. 5 (c), a grouping is made for each of the above-mentioned modification conditions to make an input plan, and then 1 is set on the work day of the previous process.
Each day is added as a work instruction date, and the work date of each process is written in the arrangement information file to make a small schedule.

た。According to the above-described embodiment, when the process load of each process is leveled and the number of equipment setups during the planning period is set to 1, when the planned number of days is n days, the setup time is longer than that in the conventional case. Can be shortened to 1 / n, which improves the production capacity and shortens the process length.
