摘要
分析了轧制批量计划编制问题,建立了不确定轧制计划数的轧制计划VRP模型.该模型不仅考虑了轧制计划中板坯在厚度和硬度上的跳跃、板坯宽度的正反跳以及相同宽度板坯连续轧制的长度约束,而且考虑了轧制计划中烫辊材和主体材的合理安排.构造出一种基于单亲遗传算子的免疫算法用于求解此模型.生产数据的仿真结果表明,所提出的模型及算法切实可行.
Rolling plan problem is analyzed and a rolling plan VRP model with uncertain rolling plan numbers is suggested according to hot rolling production practice. The model considers not only the slab bounce on gauge and hardness, obverse and inverse bounce on width, and the rolling length constraint of the slabs with same width, but also the reasonable arranging of warm-up materials and staple materials. An immune algorithm based on partheno-genetic operators is proposed for solving the model. The simulation with production data shows that the algorithm is feasible.
