Abstract

The present invention relates to the technical field of production scheduling, in particular to a production line production sequence scheduling method, system, and storage medium. The production scheduling method includes the following steps: S1, obtaining parameter data of production line production; S2, randomly generating production line production sequence s a ; Calculate the corresponding violation rate according to the limited conditions, and establish the corresponding objective function according to the set goal; and for the randomly generated production sequence s of the production line a Perform preprocessing; the preprocessing includes: eliminating the production line production sequence s a The individual whose violation rate reaches the set value and / or the objective function does not reach the set value; S3, constructs the overall objective function, and calculates the optimal solution set of the overall objective function; S4, according to the optimal solution Set to obtain the optimal production line production sequence. The beneficial effect of the present invention is that it solves the problem that it is difficult to obtain the optimal production sequence in multi-objective production line production, and at the same time, the improved NSGA-II algorithm also solves the problem that the traditional NSGA-II algorithm takes a long time to obtain the optimal solution set.

Description

technical field [0001] The invention relates to the technical field of production scheduling, in particular to a production line scheduling method, system, and storage medium. Background technique [0002] As the market competition becomes more and more fierce, for manufacturing enterprises, in order to maintain a strong competitiveness in production, it is necessary to reduce production costs and improve production efficiency. At the same time, when there is a change in the order plan, targeted adjustments to the production arrangement can be made as soon as possible. [0003] In common large-scale manufacturing enterprises, there are often complex situations where there are huge types of raw materials for production and the production of multiple materials at the same time. It is difficult to make optimal production scheduling in such multi-objective production. [0004] The traditional NSGA-II algorithm is to generate a large number of random solutions on the computer, m...
