基于多目标优化的绿色供应链博弈模型及利润共享契约

Game models andprofit-sharing contract of green supply chain based on multi-objective optimization

为研究环境效益对绿色供应链最优决策的影响,基于多目标优化与博弈理论,构建了制造商同时考虑利润与环境双目标下的供应链博弈模型,分析了集中式与制造商主导Stackelberg博弈模式下的供应链决策,并进一步建立了利润共享契约下的博弈模型,对以上3种均衡结果进行比较。研究表明,制造商考虑环境效益目标会使自身利润减少,零售商利润、产品绿色度与环境效益相应提高,整体供应链利润先增大后减少;而利润共享契约能够实现产品绿色度、环境效益以及供应链各成员间利润的多重协调。

To research the influence of environmental benefits on optimal decision for green supply chain,a supply chain game model with profit and environment simultaneously considered by manufacturer was constructed based on multi-objective optimization and game theory,the decision for supply chain model under centralized,manufacturer-led Stackelberg game and profit-sharing contract was analyzed,and the above three equilibrium results were compared.The results showed that the manufacturer's profit would be reduced after considering the target of environmental benefits,while the retailer's profit,product greenness and environmental benefits was increased.However,a profit-sharing contract could realize multi-coordination of product green degree,profit and environmental benefits of the whole supply chain.
