延期支付条件下零售商的最优售价和订货策略

摘要

在供应商给予零售商延期支付和现金折扣的优惠政策下,进一步假设产品的年需求量依赖于零售商产品售价的基础上,建立了由一个零售商和一个供应商所构成的库存决策模型,扩展了经典的经济生产批量(EPQ)模型.通过模型的分析求解,可以得出零售商在上述情况下的最优订货周期、最优售价及最优付款时间的简单判定方法.最后,通过算例,验证了模型的可行性,得出了与实际相符的结论.%The main purpose of this paper is to develop an inventory model under permissible delay in payments, in which the supplier provides not only a permissible delay but also a cash discount to the retailer, where the demand rate is considered to be a function of the retail price. This model further expands the classical economic production quantity(EPQ) model. We do this in order to reflect the real-life business situations. Mathematical models have derived for obtaining the optimal pricing, optimal cycle time and optimal payment time for items. Finally, a numerical example is given to illustrate the results developed in this paper.
