摘　　要：像计算机、电视机、空调等这类具有物理变质的可能性很小,但生命周期较短、不断更新换代、价值不断贬值的电子产品会发生无形变质的现象.在假设无形变质率与需求率负相关,同时在产品的存储过程中,考虑库存水平对销售量的影响情况下,研究需求受库存水平影响、且缺货时存在延迟订货的短生命周期物品的库存管理问题.创新之处在于考虑了产品的缺货问题;在允许缺货的条件下,建立了短生命周期物品的库存模型;运用数值算例进行了求解和验证;并对各参数进行了敏感性分析.Like the computer, TV, air conditioning, which has physical deterioration of the possibility is very small, but the life cycle is short, and constantly upgrading, the depreciation of value electronic products will happen deterioration phenomenon. The paper assumes that the deterioration rate is negatively related to the demand rate, at the same time in the storage process of the product, we consider inventory levels influencing on sales situation, the stock dependent demand, and shortage of inventory management problems of short life cycle delay ordering of items. The innovation of this article is to give full consideration to the shortage of products; allowing stockout condition, establishes inventory model for short life cycle of goods; a numerical example is solved and verified; and the parameters of a sensitivity analysis.
