面向瓶颈漂移的制造车间生产过程优化关键技术
Key Techniques of Production Process Optimization in Manufacturing Shop Oriented to Bottleneck Shifting
摘要
Abstract
Aiming at the problem that the optimal system performance could not be achieved by using the decision of production process optimization ,which was resulted from the passive response to changes of bottleneck ,an optimization method of production process oriented to bottleneck shifting was constructed and its key techniques were studied to realize initiative ,global superiority and timeli-ness of optimization .Firstly ,the optimization procedure of production process w as established ,w hich contained determination of optimum bottleneck position ,bottleneck prediction ,combinatorial optimi-zation of bottleneck shifting factors and optimization of scheduling .Secondly ,taking system global benefit maximization as the goal ,a modeling and simulation technology-Flexsim was used to determine the optimum bottleneck position ,w hich could provide basis for a combinatorial optimization of bottle-neck shifting factors .Based on analyzing importance of bottleneck factors ,a combinatorial optimization method of bottleneck shifting factors oriented to optimum bottleneck location was established ,which could make bottleneck fixed in the best location under the relative balance conditions between manu-facturing unit’s capacity and load .A mathematical model of balance global benefit was built to meas-ure impact of bottleneck shifting ,and then the driving mechanism of production scheduling was con-structed to determine the best scheduling time ,and the unnecessary optimization process of scheduling was filtered and the stability of system was improved .Finally ,the method is proved to be effective by optimizing assembly process of one vehicle parts .关键词
