[Abstract]:With the rapid development and wide application of information technology, the management of enterprises has gradually changed from traditional management to computer management. Production scheduling and scheduling is an important part of manufacturing execution system, which is directly related to the production and management efficiency of enterprises. An effective scheduling scheme can efficiently utilize production resources, reduce production costs and improve the competitiveness of enterprises. Job shop scheduling problem is a very complex problem. In this paper, genetic algorithm and simulated annealing algorithm are studied in detail, combining the advantages of genetic algorithm (GA) and simulated annealing algorithm (SA). A hybrid genetic simulated annealing algorithm (GASA),) is proposed to efficiently solve the job shop scheduling problem. This algorithm not only brings into play the advantages of fast convergence speed of genetic algorithm and wide search range of simulated annealing algorithm, but also overcomes the problem that the former converges prematurely and the latter converges slowly. This not only prevents the algorithm from falling into the problem of local optimal solution, but also improves the convergence speed and search efficiency of the algorithm. Based on GASA algorithm, a distributed NC system workshop scheduling system based on Java EE platform is designed and implemented. The main purpose is to achieve job scheduling and real-time control and management of production process. The system is based on the B / S architecture and can be subdivided into the following layers: presentation layer, business logic layer and Dao layer, domain object layer and database service layer. It uses Struts Spring and Hibernate framework. In particular, it uses Struts framework to implement presentation layer and Web layer, Spring framework to implement business logic layer, and Hibernate framework to implement persistent link of database.
