需求率取决于库存水平的库存模型是基于常见的现实生活观察，即更大的产品可用性往往会刺激更多的销售。以前的模型，包括库存水平依赖的需求率假设持有成本是恒定的整个库存周期。本文研究一类需求率与库存水平相关、持有成本与存储时间相关的产品的库存策略。假设单位时间内每单位物品的持有成本是存储时间的递增函数。考虑了两个与时间相关的持有成本阶跃函数：追溯持有成本增加和增量持有成本增加。程序开发用于确定最优的订货量和最优的周期时间的成本结构。
Inventory models in which the demand rate depends on the inventory level are based on the common real-life observation that greater product availability tends to stimulate more sales. Previous models incorporating inventory-level dependent demand rate assume that the holding cost is constant for the entire inventory cycle. This paper considers the inventory policy for an item with a stock-level dependent demand rate and a storage-time dependent holding cost. The holding cost per unit of the item per unit time is assumed to be an increasing function of the time spent in storage. Two time-dependent holding cost step functions are considered: Retroactive holding cost increase, and incremental holding cost increase. Procedures are developed for determining the optimal order quantity and the optimal cycle time for both cost structures.
