考虑生产组织约束的钢铁企业合同计划

Order planning for iron and steel enterprise considering production organization constraints

针对典型钢铁生产流程A,分析实现流程高效运行的铁钢界面、脱磷与脱碳转炉、精炼设备以及铸轧界面的生产组织约束。建立了考虑生产组织约束的钢铁企业合同计划模型,模型中充分考虑了不同生产线的排产紧凑与协调以及合同投产日期的优化,之后采用禁忌搜索算法对模型进行了求解。最后,从钢厂A中随机选取3组不同规模的实际生产合同,并对其进行仿真实验。仿真结果表明:所建立的合同计划模型与求解算法能够有效协调和优化生产,实现钢铁制造流程高效运行。

To realize efficient operation,the production organization constraints of ironmaking/steelmaking interface,desulphorization basic oxygen furnace and decarburization basic oxygen furnace,refining equipment and casting/rolling interface of typical steel production process A are analyzed.Order planning model of iron and steel enterprises considering production organization constraints is established.The scheduling compact and coordination and the optimization of commissioning date of different production lines are fully considered in the model.Then,the model is solved by tabu search.Finally,three different sizes of actual production contracts which are randomly selected from the steel plant A are simulated.The results prove the presented model and algorithm can harmonize and optimize the production effectively and also realize the process running efficiently.
