分析了钢铁企业APS理论和应用研究现状,总结了钢铁生产计划体系中的优化问题和求解方法,在此基础上,提出了钢铁企业APS优化引擎的软件模型ISMA。模型以通用性、独立性、可重用性和可扩展性为目标,分为接口层、求解层、模型层和算法层,阐述了各层的分工和协作方式。最后以钢轧一体化批量计划编制问题为例,说明了模型的应用方法。
By analyzing the research on APS theory and its application in iron and steel enterprises and summarizing the optimization problems and their solving solutions in steel production planning hierarchy,this paper proposed a software model for steel enterprise APS optimization engine,called ISMA.Aiming at having universality,independence,reusability,and extensibility,this model consisted of interface layer,solving layer,model layer,and algorithm layer,discussed the model's functions and cooperation mechanism.Finally by taking batch plan problem of integrated steel production as example,presented the application method of the ISMA model.
