摘要
在需求和采购价均为时变函数的EOQ模型基础上,考虑物品变质和存货影响销售率现象对库存管理补充策略的影响,建立了相应的EOQ模型,由模型的最优解分析知,库存系统的总成本函数在给定条件下是服务水平的凸函数。运用Mathematica4. 1版软件进行数值仿真和灵敏度分析,表明最优解存在且对库存系统的各种参数具有不同的敏感性。
An EOQ model is developed for deteriorating items with time-varying demand and purchase price under stock dependent selling rate. The total cost function is convex with respect to service level, and the existence of optimal solution is discussed. A numerical example and sensitivity analysis are presented to illustrate the model by the software Mathematica version 4.1. The parameters associated with the model affect the optimal solution in various degrees.
