考虑产出不确定的供应链绿色制造策略研究

Research on the Strategies of Green Manufacturing in Supply Chain with Yield Uncertainty

构建了一个由两个对称性供应商和一个制造商组成的绿色供应链模型,通过博弈论方法探讨了消费者绿色偏好和制造商产出不确定的影响。结果表明:(1)消费者绿色偏好系数越高,对渠道成员越有利。(2)产出不确定对制造商具有负向影响,但对供应商的影响将随着产出不确定的提高,由正向影响转向负向影响。(3)考虑成本分摊的收益共享契约可以协调供应链。在此基础上,针对供应商之间的三种不对称情况(成本的不对称,产出不确定的不对称和渠道权利结构的不对称),探讨了不对称性对渠道成员决策以及收益的影响。最后,通过数值分析进一步研究了在不同情境下产出不确定对渠道成员收益影响的差异。

This paper constructs a green supply chain model consisting of two symmetric suppliers and one manufacturer, and explores the influence of consumers’ green preference and manufacturer’s yield uncertainty through the game theory. The results show that, firstly, the higher the coefficient of consumers’ green preference, the better the channel members.Secondly, the yield uncertainty has a negative impact on the manufacturer, but the impact on the supplier will shift from the positive to the negative as the yield uncertainty increases.Thirdly, the revenue-sharing contract with cost-sharing can coordinate the supply chain. On this basis, it is discussed at three kinds of models with asymmetric suppliers(cost asymmetry, yield uncertainty asymmetry and channel power structure asymmetry),to explore the influence of asymmetric suppliers on the decision-making and outcomes of the channel members. Finally, the differences of yield uncertainty in channel members’ outcomes under different scenarios are further studied through numerical analysis.
