摘　　要：在短期价格折扣的背景下,分析了零售商对非即时易腐品的促销决策。零售商决策促销价格和促销期,根据促销期长度与产品保持不腐败时长的关系,零售商有"价格折扣"和"折扣加买赠"两种促销策略。特别地,第二种策略是指产品发生腐败阶段,零售商在价格折扣的基础上结合买赠的销售方式以减少商品的腐败损失。通过建立该问题的数学模型,以最大化零售商的年利润函数,证明了每个分段内目标函数的性质,并设计求解步骤对该问题进行求解。通过数值算例和灵敏度分析,验证了模型和算法的有效性,并得到不同参数组合对非即时易腐品促销策略选择的影响。The retailer’s promotional strategy for non-instantaneous deteriorating items is analyzed under temporary price reduction.The retailer decides the sale price and special sale time,and retailer’s promotional strategies include price discount strategy and price discount with extra-product promotions strategy according to the relationship between the length of the special sale time and the length of time in which the product has no deterioration.Specially,the second strategy refers to the retailer employing both ways of price discount and extra-product promotions during the time span when items deteriorate to reduce deteriorating loss.The proper mathematical model is formulated to maximize the retailer’s yearly profit.Then the properties of the objective function in each scenario are derived,and a solution procedure is proposed to solve the problem.Numerical examples and sensitivity analysis are conducted to illustrate the developed model and the solution procedure,and the impact of different combinations of parameters on the retailer’s promotional strategy choice for non-instantaneous deteriorating items are also derived.
