Two-Stage Perishable Inventory Models
研究两种需求类型的易腐品库存系统，通过两阶段库存模型近似系统性能并比较两种管理策略，对库存管理者和运营研究人员有参考价值。
In this paper we consider perishable inventory systems with two types of demand. Demand may be for either fresh items or for somewhat older items. We model the system with two inventory stages. The first stage holds fresh items and the second stage holds the older items. We approximate the performance of the two-stage inventory system and compare two managerial policies.
