-
摘要: 基于2工序成组生产系统的生产量与作业顺序的优化模型,扩展并建立了成组流水线上多品种多工序 加工时生产计划和调度的集成模型.针对这一模型的特点,提出了1种二进制编码与有序编码相结合的2层次 遗传优化方法.最后给出了计算实例,计算机模拟结果说明了这一方法的有效性.Abstract: Based on an optimal model of production-amount and job sequencing of a two-stage group production system, amathematic model forturnout and job sequencingwithmulti-product andmulti-machine is proposed. In accordance with the feature of the proposed model, it is solved with a two-level genetic optimization method that combines binary-coding and order-coding. An example is presented, and the simulation result verifies the efficiency of the method.
