| 摘 要： | 炼钢-连铸生产过程中存在扰动,致使很多时候生产不能按原调度计划进行,需要进行重调度.重调度时存在正在生产的炉次计划,因此重调度问题比静态调度问题更具有复杂性.将具有相同精炼重数的炼钢-连铸生产重调度问题归结为一个复杂的混合Flow Shop调度问题,考实际生产约束,以最小化最大完成时间为目标建立了重调度模型,采用了启发式规则和遗传算法相结合的优化方法求解.利用实际生产数据对重调度方法进行了验证和分析,结果显示了重调度方法的有效性.

| Abstract: | Disturbances upset the plan in steelmaking-continuous casting(SCC) production,which makes plan infeasible.Rescheduling is highly needed.Since producing charges exist,rescheduling problem is more complex than the static scheduling.In this paper,the rescheduling problem of SCC with the same refining phase is inducted a complex hybrid flow shop(HFS) scheduling problem.A rescheduling model is developed based on practical production constraints and minimizing makespan,which can be solved using hybrid genetic alg... |
