摘　　要： 科技进步和顾客需求快速变化使产品生命周期越来越短，一些生命周期较长的耐用消费品，因其时尚性等特点，逐渐变成易逝品。假设供应商提供部分信用交易，而零售商在计划期内周期性地订购一种生命周期为2个补货周期长度的产品以满足不确定性需求，零售商以计划期末的期望资金水平最大化为目标，其订货时可以使用自有资金和／或贷款资金，订货后如果有剩余资金，也可以通过无风险投资获得收益。建立了部分交易信用下的易逝品动态库存控制模型，证明了此库存系统存在最优补货策略，对最后一个周期给出了“临界值”订货策略。最后，通过算例进行了说明。 The product life cycles are getting shorter with technological advancements and customers demand changing rapidly, and some long life-time durable consumer goods gradually become perishable products because of fashion and other characteristics. In this paper, a stochastic dynamic inventory model is developed for perishable products where a retailer periodically purchases a product of two-replenishment-period life cycle from a supplier and sells it to a market with random demands. In each period, offered partial trade credit the retailer use his own capital and/or borrow a short-term loan to purchase the product, and the surplus cash （if any） can be invested to earn risk- free interest. The objective is to maximize the retailer＇s expected terminal cash at the end of the planning horizon. The existence and uniqueness of the optimal polices are proved for given initial capital and inventory level and the critical- number policy is presented for the last period. A numerical study is given to illustrate the findings.
