价格和库存均影响需求的易腐品模型

An EOQ Model for Perishable Goods under Price-and Stock-dependent Demand Rate and Time-dependent Partial Backlogging

蔬菜、水果等物品在存储的过程中随时间的推移会发生大量的损耗。假定产品的需求受库存和销售价格的影响,在有限计划期内建立时变拖后供给的易变质品库存模型,给出一种寻求最优订货次数和销售价格的简便方法,并分析参数变化对于订货次数、平均利润和服务率的影响。

Commodities such as vegetables and fruits are subject to direct spoilage while kept in store. This paper assumes the demand rate is price - and stock - dependent. With an EOQ model by proposing a time - dependent backlogging rate to make the theory more applicable in practice, where deteriorating rate is constant, it presents a method for finding the optimal replenishment schedule for the EOQ model with deteriorating items. It also makes a sensitivity analysis on the optimal solution with respect to parameters of the system.
