Abstract

The invention discloses a method for realizing dynamic production scheduling in an energetic material production process. The method comprises the following steps: selecting a production scheduling task and determining the batch number of products, the processing time of each process of the products and the type number of equipment required by the process in the production scheduling task; identifying bottleneck equipment in the scheduling task by adopting TOPSIS based on sensitivity analysis and a comprehensive evaluation method; and adopting a genetic algorithm to obtain a production scheduling scheme with the least completion time. The invention further discloses a system which comprises a data management module, an operation scheduling module, a scheduling simulation module and a usermanagement module. According to the method, the energetic material scheduling problem is solved by adopting an improved genetic algorithm based on bottleneck information, and the processing sequence of the products is determined and the given optimization target is completed by reasonably distributing production resources and processing equipment under the condition of meeting constraint conditions, so that the production efficiency is improved, the production cost is reduced, and the enterprise competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of production scheduling of energetic materials, specifically, a method and system for realizing dynamic production scheduling of energetic materials production process. Background technique [0002] The actual production process of energetic materials is often accompanied by abnormal conditions such as machine failures and changes in processing time. The production plan is easily disrupted by emergencies. Only relying on the subjective experience of production schedulers to make decisions is very important for the timeliness and reliability of emergencies. The pertinence is poor, resulting in problems such as increased product production cycle and system inventory, and low resource utilization. In recent years, many scholars at home and abroad have carried out a lot of research on production scheduling optimization methods. However, due to the characteristics of fixed process flow, long production cycle, an...
