两阶段需求相关的动态易逝品最优订货策略

Optimal order policy for dynamic perishable product with demand correlation between two periods

以动态市场环境下的易逝品为研究对象,针对两阶段需求相关、每次订货时带有固定的订购费用以及未满足需求部分延期供给等实际现象,建立了动态易逝品销售商两阶段订货决策模型.对模型的最优解进行了理论分析,并提出了寻求两阶段订货策略的简单方法.以朗科优盘经销商的采购实例来说明该模型的应用价值.最后,通过探讨订货决策与需求波动、两阶段需求相关系数以及延期供给率等因素的关系,得出了一些重要的管理启示.

This paper develops a two-period order decision model for the dynamic perishable product. The theoretical analysis of the optimal solutions to the considered problem is presented, and a simple method for finding the optimal two- period order policy is given as well. A practical purchasing example of Netac USB flash driver is presented to illustrate the application of the model. Finally, according to the investigation of the relationships between the order decision and such factors as the demand fluctuation, the correlation coefficient of two-period demands, and backlogging rate, some important managerial insights are obtained.
