摘要: 在库存管理研究中,单独实现产成品或原材料库存成本最小,往往无法获得整个库存系统的最优控制策略.本文提出了一种同时考虑产成品和原材料库存成本的变质物品EPQ集成模型.运用迭代寻优法得到模型最优解,得出计划期内最优原材料订购次数,原材料订购周期内的最优生产次数和最优服务水平,并对主要参数进行了灵敏度分析,为生产制造企业的库存管理提供了决策依据.

关键词: 变质物品, 库存成本, EPQ模型, 短缺量拖后率

Abstract: Separately minimizing either inventory cost of finished good or that of raw material can hardly make the manufacturer get optimal control strategy in the study of inventory management.This paper develops an integrated EPQ model jointly considering both inventory cost of finished good and that of raw material.The unique optimal solution is found as a set of parameters consisting of optimal order times of raw material,optimal production times in order interval of raw material and optimal service level by means of an it erat ive sear ch met ho d.T he main parameters are given a sensitivity analy sis.The evidence is provided for the inventory decision-making of those production enterprises.

Key words: deteriorating item, inventory cost, EPQ model, backlogging rate
