摘 要: 在考虑变质性产品的市场需求率是库存水平的线性分段函数、缺货期的需求率与缺货量相关的情形下,建立了由单供应商和单零售商构成的二层供应链协调模型,研究了供应商如何设计数量折扣计划来激励零售商合作,使其自身利润最大化的同时实现供应链系统完美协调问题.理论证明了模型最优解的唯一存在性,同时提供了相应的求解方法.数值算例说明该协调策略对于改善供需双方绩效和供应链运作协调是十分有效的. The quantity discount model for deteriorating items is established in two-echelon supply chain consisted of a supplier and a retailer in the situation of considering linearly stock-dependent demand and allowable shortage,where the backlogging demand is influenced by the negative inventory level during the stock out period.The paper studies how the supplier designs quantity discount strategies so as to maximize his/her own profit and realize the perfect coordination of the supply chain system.The uniqueness and existence of optimal strategies are testified theoretically,and a simple resolving method is provided.Numerical examples show that the strategy is effective in improving the supply chain coordination and the profits of two parties.
