Abstract

The invention relates to an optimal scheduling method based on multi-plant steelmaking-continuous casting billet production process, and belongs to the technical field of intelligent optimization scheduling of metallurgical manufacturing production processes. The invention optimizes the target by determining a scheduling model and an optimization target of different billets during the multi-plantsteelmaking-continuous casting billet production process and using the optimal scheduling method of a mixed fruit fly optimization algorithm, wherein the scheduling model is established according to the processing time of different billets on different steel mill machines, and the goal of optimization is to minimize the maximum completion time. The method provided by the invention can find production plans of each plant in a short time to avoid resource waste of each plant, and minimize the maximum completion time Cmax(pi) of each plant, thereby reducing the production cost and improving the production efficiency of the plants.

Description

technical field [0001] The invention relates to an optimal scheduling method based on the multi-factory steelmaking-continuous casting billet production process, and belongs to the technical field of intelligent optimal scheduling of the metallurgical manufacturing production process. Background technique [0002] With the advancement of science and technology and the increasingly fierce market competition, the iron and steel industry is developing towards high efficiency, low cost and stable production. Production scheduling plays an important role in the efficient and stable production process of steel mills, which is the core function of the modern steel production management system. The steelmaking-continuous casting section plays an important role in the steel production process. The goal of billet production scheduling is to design a reasonable production scheduling plan, make full use of existing equipment resources, reduce process waiting time and eliminate operatio...
