基于横向补货的库存协调近似模型

以给定零售商独自拟定订货策略为前提,提出了一种在横向补货允许的情况下,能够有效地刻画系统库存的近似模型.该模型在"最近邻居"优先补货原则下,详细地阐述了系统中的产品需求走势和相应的需求满足率.并通过和仿真试验的数值结果进行比较,验证了该模型的有效性,还对横向补货允许和补货不允许两种不同情况下的系统库存成本进行了比较,形象地给出了横向补货策略在优化库存成本方面的绩效.关于单个零售商订货策略一般性的拓展以及系统联合订货策略的可能性研究也给予了相关说明.

An Approximate Model for Lateral Transshipments in Multi-retailer Inventory Systems

In this paper, given each retailer has his own order policy, an approximate model is proposed for lateral transshipments in multietailer inventory systems. The performance of this model was evaluated in a simulation study. Moreover, cost of inventory systems without lateral transshipments is given and compared with the cost of inventory systems with lateral transshipments. Some simple discussion of extension on order policy of retailers is also involved.
