【摘要】 模铸的组炉问题属于钢铁生产计划与调度问题之一。模铸组炉问题与炼钢一连铸的组炉问题相比,在工艺约束及计划编制规程上均有差异。在分析了模铸组炉与炼钢组炉差异的基础上,综合考虑了模铸组炉的工艺规程及约束,建立了模铸组炉的车辆路径问题(VRP)模型。并针对该模型的特点,提出了蚁群优化求解算法。通过实际生产数据对模型及算法进行了实例验证,结果表明了提出的模型及算法的有效性与可行性。更多还原

【Abstract】 Group charge problem of ingot casting is one of iron & steel production planning and scheduling problems.Compares with the steel-making - continuous casting’s group charge problem,the ingot casting’s group charge problem has the difference in the process constraint and planning rules.On the basis of analyzing the difference between group charge problem of ingot casting and group charge problem of steelmaking,VRP model for group charge problem of ingot casting is established in consideration of technological regulation and process constraint.Aiming at characteristic of model,ant colony optimization (ACO) algorithm is proposed for solving the model.The experimental result using practical production data shows the proposed model and algorithm are effective and feasible.更多还原
