包含逆向物流的供应链库存控制问题研究

Research on Inventory Controlling of Supply Chain Based on Reverse MF

逆向物流的参与使得供应链库存管理问题更加复杂,为了切合物流运作的实际,本文在介绍逆向物流库存控制的最新理论———收集商管理库存(CMI)的基础上,引入逆向物流产品回收率a和修复率b两参数,建立了逆向物流产品到达服从泊松分布,产品修复周期为L的连续库存控制模型。经求解,模型的订货周期T和订货批量Q与修复周期L无关,是关于回收率a和修复率b的减函数且都较经典EOQ模型的订货周期和订货批量小。

Because of the reverse MF, supply chain inventory controlling is very difficult. This paper introduces a new idea about controlling inventory for reverse MF called Collector Managed Inventory （CMI）. In order to simulate the fact of MF, we introduce two parameters. Which are recovery efficiency （a） and repair efficiency （b）, and suppose the cycle of repair is L, then we present a new inventory controlling model. From the results of the model, we can see that the order cycle （T） and the order quantity （Q） are disrelated to L, they are the decreasing function to a and b, and smaller than the classical EOQ model.
