3、环供应链管理思想的核心可概括为 再制造、节约、集成、合作、双赢 , 这就要求供应链上的各个节点企业建立一种相互协作、相互促进的关系。然而, 在传统的供应链管理中,各节点企业都是以自身的效益最大化为目标而进行的独 立决策,这样就不能使整个供应链实现帕累托最优的状态。因此,需要设计一种 协调机制将供应链上的各节点企业集成起来,以实现企业之间的合作和双赢。闭 环供应链协调契约作为一种新型协调机制,正越来越受到国内外学者的关注和重 视。特别是当供应链处于风险环境时,如何采取有效的规避和预防措施是供应链 管理中面临的又一挑战。因此,本论文针对无风险环境和 Downside-risk风险 环 境下不同的风
4、险规避主体展开深入研究,主要研究内容如下: (1) 不考虑供应链所面临的风险环境,基于 Stackelberg博弈理论,分别从 供应链上各节点企业进行分散决策和集中决策两个角度来切入,得出各节点企业 在分散决策下的最优产品订购量并未达到真正的 最优 。因而,整个供应链是 不协调的。进而,加入收益共享契约来协调供应链,并求出保证收益共享契约实 施有效的收益分配系数的取值范围。 (2) 运用 Downside-risk风险约束对一个三阶段的闭环供应链中具有风险规 避的零售商与其上游具有风险中性的分销商和供应商之间的 协调进行契约设计 和建模。研究发现,在收益共享契约的激励下,零售商的风险约束无法得
5、到满足, 整个供应链无法实现协调。从而,设计风险共享契约,刺激零售商增大产品的订 购量,使契约条件下的风险约束得到满足。同时,供应链上各参与方的收益都有 所增加,风险中性的一方会对风险规避的一方提供一定程度的风险保护。 (3) 同样针对收益共享契约下的三级闭环供应链,加入 Downside-risk约束, 并针对分销商的实际下行风险大于其可以接受的最大水平的情况重新设计新的 扩展契约,分契约协调主体为供应商和零售商两种情况展开讨论,求出 保证契约 实施有效的协调价格的取值范围。得出在扩展契约下利润增量会有所增加,同时, 下行风险也会有一定程度的降低的结论。 关键字 :闭环供应链,契约协调机制,

However, in the traditional supply chain management, each node makes decision independently aims to maximize the benefits respectively. The result of independent decision-making is that impede the whol

Therefore, it needs to design kinds of coordination mechanisms for integrating enterprise nodes and sign coordination contract between each other in order to achieve cooperation and all-win. As a new coordination mechanism, closed-loop supply chain coo

Especially, when the supply chain is at risk, how to take effective and preventive measures to avoid is a difficult problem and a challenge that faced of the enterprises in supply chain management.
10、Consequently, this paper bases on whether the supply chain is at risk and different risk aversion under Downside-risk conditions in-depth study of the subject, the main research contents are as follows: 1. At first, it does not consider the risk that the supply chain faced, it respectively considere
