[Abstract]:In this paper, the production planning problems of continuous casting and hot rolling are studied, including the establishment of continuous casting and hot rolling production planning model, the heuristic algorithm and intelligent optimization algorithm for solving this model, and the design and development of continuous casting and hot rolling production planning system. The main work of this paper is as follows: 1. This paper describes the practical background of continuous casting and hot rolling problems, including products, production lines, production capacity, system requirements and so on. On the basis of the analysis, the key information of continuous casting and hot rolling is obtained, and the related tables are established. Then, a global mathematical model of continuous casting and hot rolling production planning problem is established, which aims at the minimum number of roll switching times in hot rolling stage and the minimum number of tundish (casting times) used in continuous casting stage. And the simplified mathematical model of hot rolling production planning with the goal of minimum roll switching times is given and the comparison between the two models is given. The heuristic scheduling rule and intelligent optimization method are used to solve the continuous casting and hot rolling production planning problems. The heuristic scheduling algorithm based on the practical experience of continuous casting and hot rolling production planning can successfully solve the problem and obtain a better initial solution. In order to optimize the production planning results of continuous casting and hot rolling, particle swarm optimization algorithm and genetic algorithm were applied to solve the global mathematical model of continuous casting and hot rolling production planning problem and the simplified mathematical model of hot rolling production planning problem. Finally, the three methods are compared. The production planning system of continuous casting and hot rolling is designed. First of all, the system development scheme which is composed of user interface layer, application layer and database layer is determined, and the functions of each layer are described. Secondly, the running development environment of the system is described. The main base tables of database layer user information data, order information data, constraint information data, intermediate result information data and final result information data are designed. According to the system design, the continuous casting and hot rolling production planning system is realized. In the database layer, the automatic importing steps of Excel order data into the database wire order demand table are described, and in the application layer, the main static functions of the system are introduced, and the system has better expansibility by optimizing design. In the user interface layer, the interface of user module, order input module, process constraint module, intermediate result module and result output module and some codes are displayed. The function of automatically deriving the results of continuous casting and hot rolling production is realized.
