摘　　要：本文用斜坡型函数来描述短生命周期产品需求变化特征,用持有成本不断增加的形式来表示存货的无形变质所带来的损失,通过向供应商支付额外的赶工成本来缩短提前期,同时在允许缺货的情况下设置合理的缺货期价格折扣来控制订单的流失,即以价格折扣的损失来挽留住更多的顾客,使其总成本到达最优。本文在此基础上建立了短生命周期产品的库存模型,并提出了最优解的求解方法。This article studies inventory system for short-life cycle products,assuming a fixed life cycle and a perishable product which value deteriorates as the item gets aged.Lead time can be reduced by paying crashing cost to vender.If an item is out of stock in an inventory system in which shortage is allowed,the supplier may offer a negotiable price discount to the loyal,patient and captive customers to compensate for the inconvenience of backordering.Solution for this type of problem is worked out by capturing the deterioration in value by increasing holding cost.The demand of short-life cycle products is represented by ramp type demand.Numerical example is provided to illustrate the solution procedure.

关 键 词：短生命周期产品 提前期 价格折扣 斜坡型需求 短缺量拖后
