库存影响需求下基于两层延期支付策略的供应链库存模型

Supply Chain Inventory Model with two Levels of Trade Credit and Stockdependent Demand

研究一类货架和仓库商品共同影响需求的库存问题,采用二层延期支付策略,即供应商向零售商提供延期支付期,同时零售商也向顾客提供延期支付期;建立了相应的库存模型,得到零售商最优订购策略存在的条件及算法,最后给出数值例子和灵敏度分析.

An inventory problem of stock-dependent demand is studied in this paper,in which two levels of trade credit policy is adopted by the retailer and supplier,namely the supplier offers a credit period to the retailer and the retailer,inturn,offers a credit period to his/her customersThe article develops a mathematical model for the inventory problem and proves the existence and of the optimal ordering policy for retailer.Finally,numerical examples and sensitive analysis are presented to illustrate the developed model.
