Abstract


Job Shop (Job Shop) Production planning is an important impact on manufacturing productivity factor . Job shop production planning with the computational complexity, dynamic and multi- target binding and other characteristics, and one of the shop scheduling problem is a typical NP-hard (Nondeterministic Polynomial-hard) problems . As technology advances, the use of computer simulation for plant production and proper planning to develop the correct operating plan, you can improve plant productivity and reduce production costs. Firstly, in order to have multiple processing paths , mass-produced automobile rear axle production workshop for the study of the production process , combined with market demand , the workshop production conditions and product technology and other considerations, the use of Flexsim simulation software to the production process of the system modeling and simulation run . Then through the analysis of the simulation results , the use of process adjustment , parameter optimization method eliminates bottlenecks and optimize the production process and the final workshop on the rear axle of the multi-stage multi-process path worked out a mass production plans to meet production requirements . Secondly, the paper rear axle from the car production plant extract that contains a number of job tasks 6 6 devices work shop order production model as the object of study, to further study the use of simulation techniques for handling multi-objective problem. Study, the first to establish the production process Flexsim simulation model , followed by a detailed analysis of time and cost objectives described and established the objective function , and then create the appropriate system objective optimization model , by optimizing the analysis were obtained for the time , for tardiness / lead penalties taking into account the time and cost for a single objective, multi -objective optimization sequence of operations . Through the optimization process with the result of the operation is not a comparison , that the use of Flexsim simulation software for multi-objective optimization problem analysis can achieve better optimization results . In this paper, case studies, modeling and simulation on Flexsim key technologies and software GUI (GraphicalUser Interfaces), Experiment, OptQuest other modules function and use to do a thorough research to Flexsim software for other related research as a research tool to provide a reference work .
