需求依赖于库存水平的易腐品补货策略的优化

Optimal replenishment policy for perishable product under stock-dependent demand

确定了一个需求依赖于库存的易腐品的库存模型,首先进一步完善了吴坤山所建立的模型,其次得出库存模型的最大库存水平影响零售商限制自己的销售空间。当短缺没有意义时放宽条件,获得在短缺条件下也有利可图的模型的求解条件,通过算法得到最优解,最后用数值实验来阐述结论的可行性。

An inventory model for perishable product with stock-dependent demand is established.We first amend Wu＇ s model,and set a maximum inventory level to reflect the facts that many retail outlets have limited shelf space.Relaxing the restriction of zero at ending of inventory and shortages are not desirable.Finally,we present some numerical examples to illustrate the feasibility of the results.
