摘要
针对加工中心为汽车发动机缸盖柔性生产线瓶颈工位的问题,以减小瓶颈工序时间为优化目标,通过调整机加工序,建立一种机加工序优化方法。在分析工序原则和产线设备对工序影响的条件下,分别建立工序约束和设备约束模型;使用遗传算法解决此类多约束排序问题,并针对耦合约束关系,改进编码方式和基因交叉方法。实际应用证明此方法可以用来优化工序,降低生产节拍。
Considering the problem that the machining center is the bottleneck station of the flexible production line of the automobile engine cylinder head.By adjusting the machining process,the optimization method of machining process is established to reduce the bottleneck process time.Under the conditions of analyzing the process sequence principle and the influence of the production line equipment on the process,the"process constraint"and " equipment constraint" models are respectively established;the genetic algorithm is used to solve such multi-constrained sorting problems,and the coding method and the gene crossover method are improved for the coupling constraint relationship;the application proves that this method can be used to optimize the process and reduce the cycle time.
