VMI系统下一个物流成本控制优化模型的建立

提出了在VMI系统下一个整合库存和运输决策的分析模型，考虑一个中心仓库满足来自n个在地理位置上不同的零售商的一组随机需求。中心仓库是个越库，对补货和配送进行决策，货物库存在各个零售商处。文中同时计算了优化的补货数量和配送频率(周期)，建立一个面对泊松分布需求更新的理论模型。

A Controlling Logistics Cost Optimal Model Under VMI System

In this paper, we present an analytical model for coordinating inventory and transportation decisions in VM1 system;,, considering a central-warehouse realizing a sequence of random demands from a group of retailers located in a given geographical region. The central-warehouse is a crossdocking , making the replenishment and shipment policy, the actual inventory is held at retailers. We compute the optimum replenishment quantity and dispatch frequency (cycle) simultaneously, and develop a renewal-theoretic model for the case of Poisson demands.
