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。 Retailers often choose to promote a variety of products to increase revenue, promotional products and people’s daily lives are closely related. This paper establishes the inventory decision-making model of perishable promotional items, which can affect the demand of inventory, and allows the shortage to occur. The shortage lag rate is related to the out-of-stock quantity and waiting time that have occurred. The existence and uniqueness of the optimal solution are proved. A search algorithm for solving the optimal ordering strategy is proposed. Through the simulation experiment to verify the model and algorithm, the sensitivity analysis results of the main parameters are obtained.
