库存展示量影响需求的促销易腐品最优订货策略

The Optimal Replenishment Strategy for Perishable and Off-price Products with Stock-dependent and Capacity Constraint

零售商经常会选择多种商品进行促销以提高收益,促销商品与人民群众的日常生活密切相关。本文建立库存影响需求的促销易腐品的订货决策模型,允许缺货发生,且短缺拖后率与已经发生的缺货量和等待时间相关。证明了最优解的存在性和唯一性,提出了求解最优订购策略的搜索算法。通过仿真实验验证模型和算法,得到主要参数的灵敏度分析结果。

For improving sales performance, multi-items are often selected for promotion. Off-price item is closely related to people＇ s daily life. We discuss the inventory problem of perishable and off-price items with stock- dependent demand rate. Some customers are more impatient to wait, therefore the sale opportunity is reduced and a bigger shortage leads to a larger loss. The existence of the optimal solution to the model is discussed, and a search algorithm of the optimal order strategy is provided. Simulation experiments are presented to illustrate the model and the main parameters are carried out.
