摘要
在现实中,企业所拥有的仓库容量是有限的。而在某些情况下可能发生购买量
或生产量超出自有仓库容量的采购或生产,对于超出自有库存容量的物品,就必须
存放于租用仓库中。这就是目前研究较多的两仓库库存问题。随着科技的不断进步,
无形变质对库存的影响作用越来越大,无形变质商品的两仓库库存问题越来越重
要。
首先对两仓库库存管理相关的研究进行了总结,对商品无形变质进行了分析。
针对无形变质的商品,根据商品的需求不同,分成了两类模型。一类是库存依赖性
需求的无形变质商品模型,研究了不存在缺货以及批量价格折扣下,零售商平均库
存成本最低的最佳采购批量、补货周期,用算例进行了验证,并分别对各参数进行
了敏感性分析。第二类模型是研究时变需求的无形变质商品的两仓库库存模型。分
别就是否存在缺货,缺货是否可延期交货,是否考虑通货膨胀建立了三个模型。模
型研究了零售商平均库存成本最低情况下的最佳采购批量、补货周期。证明了与补
充率无限大的变质商品两仓库库存系统相比,有限补充率的情况下库存更新周期更
长,而库存平均成本更低。与不考虑通货膨胀的无形变质商品两仓库库存系统相比,
考虑通货膨胀率的情况下,库存的更新周期变长,订货批量变大,而库存平均成本
降低。最后用算例对模型进行了验证,分别对各参数进行了敏感性分析。

Abstract
In practice, the capacity of any warehouse is limited. However, there usually exist
various factors that the decision-maker of the inventory system to order or product more
items then can be held in his own warehouse. Therefore, for the decision maker, it is very
practical to determine whether or not rent other warehouse. This is two-warehouse
inventory model. Along with the development of economics, advancement of science, the
products life cycle ing shorter and shorter, it means that the research of value
deterioration inventory model became important and significance. This paper studied
two-warehouse inventory model with price discounts for bulk purchases and value
deterioration items.
First, this paper presented a review of the two-warehouse inventory management
literature, and analyzed the character of value deterioration. We can divide our research
into two parts. The first part studied two-warehouse inventory model with the
stock-level-dependent demand and value deterioration. Here shortages are not allowed. A
computational procedure is proposed to obtain the optimal replenishment quantity, the
optimal replenishment cycle, which make the average total cost of the system to be
minimum. Finally, some numerical examples for illustration are provided and sensitivity
