摘要
本文以极大代数法为建模工具,建立起铝板轧制控制系统的模型.根据轧机与工件之间的加工条件规则,构造轧制系统的多队列多服务器模型.通过对基于极大代数法的生产线闭环线性模型的分析,研究了不同的铝板轧制队列对系统稳态周期性能的影响.以最短轧制周期为优化目标,运用摄动分析法对调度队列进行研究;通过周期配置得到铝板轧制的优化调度方案.
The aluminum plate rolling control system is modeled by max algebra theory. According to production condition rules between the rolling mill and the workpieces, a multi-server/multi-queue model can be constructed for the rolling system. The max-algebra-based closed-loop model of the production line is analyzed, and the influences of different aluminum plates rolling queues on the system stable cycle performance is studied. The optimazation aim is to minimize the rolling production cycle, and the scheduling queue is studied with perturbation analysis. The optimal scheduling plan for aluminum plate rolling can be obtained with the period assignment method.
