一个带有增加量价格折扣的两货栈库存模型

A Two-Warehouse Inventory Model with Incremental Quantity Discounts

已有的确定性两货栈(其中一个是自己货栈(OW);另一个是租用货栈(RW))库存模型通常不考虑增加量价格折扣,然而在实际生活中,增加量价格折扣却是促使库存管理者加大订货量的一个重要原因.本文通过考虑增加量价格折扣而将两货栈系统作了进一步扩展,在采用间隔式运输模式运送RW的物品到OW的情形下,建立了一个带有增加量价格折扣并允许短缺的两货栈库存模型,提供了一种寻求最优库存策略的简单方法.

The existed deterministic two-warehouse （One is own warehouse （OW）; the other is rented warehouse （RW）） inventory models usually did not consider incremental quantity discounts. However, in real life, incremental quantity discounts is an important factor that makes inventory manager to enlarge order quantity. This paper further extends two-warehouse system by incorporating incremental quantity discounts. A two-warehouse inventory model with incremental quantity discounts and shortages permitted is developed under the situation of shipping items in RW to OW through employing intermittent shipment pattern. A simple method is provided for finding the optimal inventory policy.
