Abstract

The invention relates to the technical field of production scheduling, in particular to a production line production sequence scheduling method and system and a storage medium, and the production scheduling method comprises the following steps: S1, obtaining parameter data of production of a production line; S2, randomly generating a production line production sequence sa; calculating a corresponding violation rate according to a limiting condition, and establishing a corresponding objective function according to a set objective; preprocessing the randomly generated production line production sequence sa, wherein the preprocessing comprises the following steps: eliminating individuals of which the violation rate reaches a set value and / or the objective function does not reach the set value in the production line production sequence sa; S3, constructing an overall objective function, and calculating an optimal solution set of the overall objective function; and S4, obtaining an optimal production line production sequence according to the optimal solution set. The method has the beneficial effects that the problem that the optimal production sequence is difficult to obtain in the production of a multi-objective production line is solved, and meanwhile, the improved NSGA-II algorithm also solves the problem that the time for solving the optimal solution set by the traditional NSGA-II algorithm is long.

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...
