Automatic production scheduling method suitable for discrete industry

Abstract

The invention relates to an automatic production scheduling method suitable for a discrete industry. The method comprises the following steps: carrying out process path modeling on each product, and carrying out productivity modeling on each station on the process path; arranging order priorities; calculating the time consumption of the products produced by each order on each station; calculating the starting time and the ending time occupied by the products produced by each order at each station; and according to the order priority, distributing each starting time and each ending time to each station. According to the automatic production scheduling algorithm, the manpower consumption of full-manual production scheduling can be reduced. According to the method, when the coping plan is seriously inconsistent with the reality, or an emergency order needs to be responded, the production can be quickly rearranged. Therefore, for enterprises, the difficulty of planned production scheduling can be greatly reduced, and the enterprises can quickly cope with changes of market demands and flexibly adjust production plans, so that the purposes of reducing cost and improving efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of production scheduling, in particular to an automatic production scheduling method suitable for discrete industries. Background technique [0002] After receiving an order, a manufacturing enterprise needs to make overall arrangements for the entire production of materials, personnel, and equipment production lines. Responsibility for planning arrangements is usually performed by a planning specialist. According to the sales order, inventory, work-in-progress and remaining capacity, the planning specialist arranges the production plan for the newly received order, and implements the plan into a daily production task and sends it to each process. At present, most manufacturing enterprises in the industry use all manual operations to collect production factor information, plan production and issue production tasks. [0003] There are several problems with manual scheduling: [0004] 1. It is difficult to ...

AI Technical Summary

Problems solved by technology

[0004] 1. Difficulty in collecting production scheduling elements: usually planners will manually check the raw material inventory, then confirm the production line capacity with the production department personnel, and review the scheduled production form before scheduling new orders

[0005] 2. It is difficult to change the production scheduling plan: when the market demand, order priority or material reserve changes, it will bring relatively big troubles to the enterprise

Because modifying the production scheduling plan at will will affect the orders that are already in production, the personnel, production lines, equipment, etc. that have been arranged in the future, and the modification is very complicated.

Therefore, for many companies, once the production is scheduled, it is usually no longer allowed to be modified, but in this way, the response to market changes is relatively rigid and slow
