基于时间Petri网的铁水物流运输系统建模

摘要

In this paper, in view of the characteristics and complexity of the rail-water logistics systems and on the basis of the time constraint of the rail-water logistics process, we used the theory and method of the time Petri net model to build the complex logistics system model of the rail-water transportation network of the Kungang steel-manufacturing factory and then, on the Extendsim platform, conducted a simulation study.%针对铁水物流系统流动途径网络化和动态复杂性特点，基于铁水物流流动时间约束，利用时间Petri网建模理论和方法，建立了钢铁厂铁水供应复杂物流系统模型，并基于Extendsim仿真平台，实现昆钢炼钢厂铁水运输复杂物流系统的仿真分析，为铁水物流路径网络优化和改进，进一步完善、提高钢铁生产过程物流运行效率、实现节能减排目标提供有益建议和指导。
