易变质原料和有保质期要求的产品的生产库存模型

A production-inventory model for deteriorating raw materialsand products with lifetime

基于生产系统与库存系统的集成关系，建立了原料易变质且制成品有保质期的产品的生产－库存模型，以每单位时期原料和产品发生的平均总费用最小为目标，确定原料的经济订货批量（ＥＯＱ）和产品的经济生产批量（ＥＰＯ）．

Based on the integrated relationship between production system and inventory sys-tem, a production-inventory model is developed for deteriorating raw materials and productswith lifetime. The objective is to minimize the average total cost per unit time of operatingthe two systems for determining the economic order quantity (EOQ) and economic productionquantity (EPQ).
