Abstract

The invention provides a casting production scheduling method and system, and the method comprises the steps: building a multi-objective weighted scheduling model according to the processing characteristics of a casting at a previous section, wherein an objective function of the multi-objective weighted scheduling model is the minimization of the average vacancy rate of a sand box and the minimization of the maximum completion time; solving the multi-objective weighted scheduling model through a hybrid genetic NEH algorithm to obtain a front workshop section scheduling scheme; establishing a flexible flow shop scheduling model according to the flexible machining characteristics of the castings in the later working section, wherein the objective function of the flow shop scheduling model isthe minimum maximum completion time; and solving the flow shop scheduling model through a whale swarm algorithm to obtain a rear workshop section scheduling scheme. According to the scheme, the problem of low casting production efficiency is solved, the production efficiency and the resource utilization rate are effectively improved, and integrated refined management and control are facilitated.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a casting production scheduling method and system. Background technique [0002] In the foundry industry, since the foundry production belongs to the production mode of single piece and small batch, the production process is long and the production scheduling plan is difficult to formulate. Moreover, due to the constraints of the production process, especially in the casting molding and smelting stage, the conditions such as the sandbox molding method, casting material and pouring temperature all have a direct impact on the quality of the casting, which is not convenient for integrated management. [0003] In the management and control of the existing casting production process, the production scheduling plan is usually specified based on the personal experience of the planner. When there are many production plans and complex production resources in the workshop, it is easy to ...
