摘要: 针对连铸—热轧一体化生产中，约束条件多且不匹配、工艺路径连续运行等特点，借助车辆路径问题的思想给出了制定轧制单位的数学模型，并基于禁忌搜索算法设计出一种求解策略．数据实验结果表明：与人工排程相比，应用本文方法形成轧制单位的板坯数平均增加了22%，对轧辊磨损的惩罚值平均减少了63%，并且排程时间明显缩短．Abstract: A mathematical model for rolling units of integrated continuous casing and hot rolling is formulated according to vehicle routing problem and solved by a heuristic method based on tabu search algorithm.Computational results on experimental data indicate that the average number of slabs included in a rolling unit is increased by 22%,the average penalty is reduced by 63%,and the solution time is obviously reduced comparising with manual work.
