库存展示量影响需求的促销易腐品最优订货策略

摘要

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.
