热轧流水线离散事件动态系统最优化

本文从随机服务系统理论的观点研究热轧流水线DEDS及其最优化问题。通过对现场操作与生产调度情况的了解以及对实际生产数据的统计分析,研究了轧制节奏和调整时间对设备作业率、产量以及拥挤现象等方面的影响。建立了以提高产量和减少碰撞为目标的随机服务系统最优化的数学模型。给出了系统解析模型的一种特殊形式和模拟结果。此工作对整个生产线的调度管理有实际意义。

The Optimization of Discrete Event Dynamical Serve System on a Hot Rolling Production Line

This paper deals with the optimization of discrete event dynamic systems (DEDS) typically repre-sented by production system on a hot rolling production linc. It studies the rolling pacing control problems by queueing theory. There the throughput rate and the collision accidence are made to be dependent on the extracting pitch and the kind of not slabs extracting from rcheating furnace. The analytical mathematical model under some conditions has been given. Some of the optimal results have been adopted in actual production management.
