炼钢—连铸—热轧生产计划编制的统一模型及智能算法

Unified modeling and intelligent algorithm of production planning for the process of steelmaking,continuous casting and hot rolling

为使钢铁企业主体工序炼钢—连铸—热轧之间的生产协调有序、提高生产计划水平和加强生产资源配置效益,运用统一建模思想进行轧制单元计划、炉次计划和浇次计划的抽象描述,从注重共性的角度统一各阶段批量计划的目标函数,通过对目标函数的组合来实现各阶段计划的有效衔接.设计基于Multi-agent的协同进化算法进行模型求解,编制炼钢—连铸—热轧—体化计划.以某钢铁企业的生产计划制定实例进行模型测试,仿真计算结果表明模型的有效性.

In order to make mutual coordination in the main process of steelmaking, continuous casting and hot rolling, improve the production plan level and enhance resource allocation benefits in steel enterprises, a unified model was applied to describe the rolling plan, charge plan and cast plan. Meantime, object functions during various plans were integrated from the perspective of universality to connect the production plan in each stage. The model was solved to make the integrated planning by a designed co-evolutionary algorithm based on a multi-agent system. Model test was performed in a steel enterprise according to its production plan, and the simulation results show that the model is effective.
