模具生产联合体加工作业统一调度问题的研究

Study on job scheduling of die & mould product union

模具生产联合体是由小规模企业组成的模具设计、制造联盟 ,由于设备、工装和人员分属于不同的加盟企业 ,其作业排序过程非常复杂。为此提出一种复合式模具生产联合体的生产排序方法 :依据基本优先规则首先完成单一工序作业 ,然后对多工序作业用改进遗传算法进行工艺优化 ,求出最优解和次优解 ,再使用评价函数法选择最佳作业路线。该方法在生产试验中取得了良好的成效 。

The mold product Union is a die & mold manufacturing job center consist of a series of Small-sized die & mold machining enterprises, This paper gives an introduction of the characteristics of processing operation on the die & mold market, advances the job scheduling based on the combination of the basic priority rules and improved genetic algorithms to optimize the process planning, and the ideal results are achieved in productive experiment.
