Abstract: This paper studies a two-warehouses system with a stock-dependent demand rate and deteriorating items. Firstly, for the cases with shortages backlogged, it respectively gives the inventory model and transportation strategy under L₁ system(keeping items just with own warehouse)and L₂ system(keeping items with own warehouse and rented warehouse ). Then for the case withshortages not backlogged,the two-warehouse inventory models are built, and also an analysis of the optimal solutionis made. At last,numercial examples are provided for retailers to make the practical inventory decision.

Key words: stock management, stock-dependent demand, deteriorating items, two-warehouse system

摘要： 针对需求受库存水平影响的变质品的两货栈系统,本文首先考虑了允许缺货但缺货要补情形下,分别给出了L₁系统(库存系统只用自己的货栈存放物品)和L₂系统(库存系统使用自己货栈和租用货栈存放物品)时,销售商的库存和运输策略模型。其次给出了允许缺货但缺货不补L₁系统和L₂系统时,销售商的库存和运输策略,并对模型最优解作了相关分析,最后给出算例,给销售商实际的库存管理提供了理论依据。
