摘要
基于需求和采购价均为时变的EOQ模型,进一步考虑时变短缺量拖后率以及资金时间价值等因素对变质物品库存管理的影响,建立了相应的EOQ模型。采用Mathematica4 1对模型进行仿真寻优和主要参数的灵敏度分析,结果显示,最优解存在且库存系统的各参数对最优库存控制策略有不同程度的影响。
<Abstrcat> An EOQ model is developed for deteriorating items with time-varying demand purchase price and partial backlogging under stock dependent selling rate and time-value of system cost.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.
