Abstract


With the development of society, increasingly fierce market competition , the traditional large-scale manufacturing systems become increasingly unsuited to the needs of people on product diversification . JIT production system can effectively reduce the production of waste, reduce costs , more and more widely . This paper studies how to use simulation technology for JIT JIT assembly and manufacturing hybrid production system design. This study includes the following three aspects: 1, introduces the time production target assembly and machining mixed model production line . Established including to minimize cycle time , changeover times , the number of cross-cell manufacturing , workshop logistics manufacturing cell volume and balance load of the target assembly and manufacture of single- piece flow mixing time production line model . 2, for cellular manufacturing system cell structure put forward an improved tabu search algorithm . Production of components with binding process for manufacturing cell structure components. By introducing the machine to generate initial solutions related degree . With this improved tabu search algorithm to solve the production line simulation model , an example simulation results with the traditional taboos and Genetic Algorithm (SGA) are compared , the results show that the improved tabu search algorithm can effectively solve the system in time for the the purpose of assembling and manufacturing mixing time production system design of cell structure problem . 3 , the establishment of a mixed assembly and manufacturing time production system simulation platform . The platform improves the current professional simulation software modeling complex , inflexible and unable to carry out their own optimization problem . In this simulation platform, users do not need to have a deep understanding of the simulation software , through the user interface, data can be entered into the system to establish production system model , but you can easily change the system layout setting , resource allocation , processing , production planning and other system information for simulation, and the image of a chart displayed in the form of simulation results. Arena simulation software with the simulation results were compared to verify the correctness of the modeling of the platform . Finally, an example to demonstrate the simulation platform to facilitate the conduct JIT production system design.
