| 摘 要： | 在炼钢-连铸生产过程中,连铸机故障会导致当前生产计划不可行,需要为故障机上未完成炉次重新分配连铸机和浇铸顺序。现行人工重分配策略无法及时响应以保证稳定和高效的生产,因此本文提出一种基于等待时间最小化的启发式炉次重分配规则,然后在此基础上建立重调度模型,并设计改进遗传算法求解该问题。采集某炼钢厂的实际生产数据进行算法验证,结果表明本文方法在连铸机出现故障时能快速给出较优的重调度方案。

| Abstract: | In steelmaking-continuous casting process, caster failure will make the current production plan unfeasible, so unfinished charges on the broken machine should be assigned to another caster and the casting sequence need to be replanned. However, current manual rescheduling strategies cannot respond quickly and ensure stable and efficient production. Therefore, a heuristic rule based on minimum waiting time was presented to reassign the unfinished charges. On this basis, a rescheduling model was created and an improved genetic algorithm was developed to solve this problem. Real cases from a steel plant verify that the proposed method is feasible and effective for rescheduling of steelmaking-continuous casting production with caster breakdown. |
