摘　　要：讨论短生命周期产品库存模型,考虑无形变质因素,并假定无形变质率与需求率成反比关系.在线性需求和常数生产率的条件下,假设,若需求率为1,则视作产品的市场生命周期结束.并且,在产品生命周期的前期不存在缺货的情况下,给出了短生命周期产品分别在理想状态、允许缺货以及价格折扣导致需求率变化等3种状态下的库存模型,最后在相同参数条件下对这3种模型进行比较,找出了单位时间内平均总成本最小的最优库存模型,厂商可以根据自身的情况选择合适的库存策略.This paper discusses three inventory models for short life cycle products with concerning the factor of value deterioration. Firstly, it assumes that the demand of product is linear change with time and the production rate is constant. It also assumes that the rate of value deterioration is in inverse proportion to the demand of products, and the market life cycle of products will be over when the demand is one. Secondly, three inventory models are developed under the condition of perfect situation, shortage allowance and change of demand due to discount respectively. The optimal inventory model which the average total cost is minimum can be obtained by comparing the three inventory models. Finally, the procedure of choosing the appropriate inventory model is analyzed and the numerical example is given.
