| 摘 要： | 本文在考虑需求率服从斜坡型分布的情况下,研究了允许缺货且缺货完全回补、变质率服从威布尔分布、补货率为无穷、有限计划期内的库存模型,证明了最优补货策略的存在性,并给出了求解最优补货策略的算法.

| Abstract: | In this paper,an inventory model with general ramp type demand rate,time dependent(Weibull)deterioration rate and finite planning horizon is studied.This model assumes that the shortages are allowed and completely backlogging,and the rate of replenishment is infinite.Then we prove the existence of the optimal replenishment policy,and present a solution algorithm to obtain it. |
