摘要: 在由单个批发商与单个零售商组成的两级时滞变质品供应链中,分别建立分散决策和集中决策下供应链系统的单位时间利润函数,通过比较得到集中决策优于分散决策的条件。引入数量折扣契约对时滞变质品供应链进行协调,促使整个供应链系统实现集中决策下的最优状态。设计收益共享合同来合理分配协调后的利润增量,保证批发商和零售商的单位时间利润都比协调前有所增加,从而实现供应链系统的帕累托改善。最后,通过数值算例演示了两种决策模式的单位时间利润情况,并分析了关键参数对供应链系统及各成员企业单位时间利润水平的影响。

Abstract: In a two-echelon supply chain of non-instantaneous deteriorating item, which is composed of a single wholesaler and a single retailer, the unit time profit function of the supply chain system under decentralized decision-making and centralized decision-making is established respectively, and the conditions under which centralized decision-making is superior to decentralized decision-making are obtained by comparison. The quantity discount contract is introduced to coordinate the supply chain of non-instantaneous deteriorating item, which makes the whole supply chain realize the optimal state under centralized decision. A revenue-sharing contract is designed to reasonably distribute the coordinated profit increment. This will ensure that wholesaler and retailer make more profits than before coordination, and the system of supply chain achieve Pareto improvement. A numerical example is used to demonstrate the unit time profits of two decision-making modes. Finally, the influence of key parameters on the supply chain system and the unit time profit level of each member enterprise is analyzed.

Key words: Supply chain coordination, non-instantaneous deteriorating item, quantity discount, no-deterioration time, deteriorating rate
