| 摘 要： | 本文采用指数函数模型来描述易逝品的成本随时间变化的特征,首先求出模型在基本假设条件下的最优订货量和订货成本,然后推导出了在订货商允许缺货、市场需求可变和订货周期可变三个扩展情景下的成本函数;最后通过计算机仿真实验,从经济性和时间效率两方面评价了本文的指数模型相对于经典EOQ模型的优势。

| Abstract: | This paper adopts an exponential function model to describe the cost-holding time relationship of perishable goods.Firstly we calculate optimized order quantity under the basic assumptions,then we set up three additional scenarios for this model and give optimized cost functions under these varied assumptions.Finally through a computer simulation experiment,we evaluate the exponential model the comparing to the classic EOQ model in both economical efficiency perspective and time efficiency perspective. |
