中文摘要：

为解决炼钢-连铸生产计划制定的可执行性与调度过程的时间不确定性影响问题,建立了一种计划调度一体化的仿真优化模型。模型以炼钢生产流程中的物流为对象,将连铸的连浇批量计划完成作为仿真的目标导向,同时考虑了过程的实时信息,并将生产调度原则抽象作为仿真模型的局域演化规则;模型可根据生产目标、过程信息按局域规则进行工位状态更新和物流迁移,从而实现目标导向下的自组织仿真。对于任意设定的时间范围,通过仿真模型的一次连续演化即得到可执行的炼钢连铸炉次计划,即初始调度方案。以某钢厂8h的生产实际数据检验了该仿真优化方法的有效性。

英文摘要：

Considering the uncertainty and complexity of production planning and scheduling in steel-making and continuous casting,an optimal simulation model is built.Based on the analysis of the logistics in steelmaking process,the casting plan is regarded as the global goal,and the procedural information is taken into account,as well as the local evolution rule that abstracted from scheduling rule.To simulate transferring of materials in the process,the state of operation sites are updated as a result of the global goals,process information and local rule.The goal-directed simulation is carried out based on the self-organization evolution mechanism.Finally,an optimal integrated production plan is made by a continuous simulation evolution.A simulation case for eight hours production plan shows that the model is valid and efficient.
