多级供应链下的CPFR系统动力学建模和仿真研究

System Dynamics Modeling and Simulation of CPFR Under The Multi-stage Supply Chain

多级供应链包含了生产商、分销商、批发商和零售商。其中,CPFR在全链间共享了库存信息、销售信息和需求预测信息,实现了全链的无缝连接。使用系统动力学对CPFR进行建模并仿真,结果表明,全链的信息共享对多级供应链的牛鞭效应有很好的抑制作用,极大地改善了供应链运作绩效。

Multi-stage supply chain includes the nodes of manufacturer,distributor,wholesaler and retailer.Under the multi-stage supply chain,CPFR is the mode of inventory,sales and demand forecast information sharing.The paper establishs the system dynamics model of CPFR and simulates.The result shows the information sharing in the whole supply chain can reduce the bullwhip effect dramatically.
