考虑产品腐烂的随机库存模型

A Stochastic Inventory Model Considering the Deterioration

假设在有限的计划时间范围内,腐烂率为常数,需求率是随机变量,根据订货量和仓库容量有限的限制,建立了一般的租借可选择的随机存贮模型.并分析了当不需租借仓库时的特殊模型,给出寻求最优周期数,最优库存周期长度的有效算法.

It is assumed that a given planning time - horizon is finite, deteriorating rate is a constant and demand is stochastic. A stochastic inventory models whether to rent or not is presented in this paper according to the order quantity and the limited capacity of storehouse. And the effective algorithm for finding the optimal number of cycles and the optimal length of inventory cycle is discussed when we could not rent the storehouse.
