The Operation Efficiency And Coordination Optimization Of The Three-level Supply Chain Under The Carbon Trading Policy

This paper studies the efficiency,the optimization and coordination of the three-level supply chain under the carbon trading policy.The three-level supply chain is composed of one supplier,one manufacturer and one retailer,to establish the Stackelberg game model under carbon trading policy,which is dominated by the upstream enterprise.We consider the operational efficiency and coordination optimization problem of the three-level supply chain under stochastic demand.Using the price of anarchy as evaluation index,the efficiency of supply chain of PoA is given upper limit.According to the research,it is found that carbon trading policy can improve the operational efficiency of the decentralized supply chain no matter we improve the price of carbon trading or increase the limit of carbon trading.In order to further improve the operational efficiency of the supply chain under decentralized decision making,and revenue sharing contract is used to analyze the three-stage supply chain coordination.The study found that the revenue sharing contract not only can make the supply chain operation efficiency to achieve optimal,but also can improve the profits of all supply chain members and achieve win-win effect.Finally,we use the numerical experiments to verify the theoretical results,analyzing the influence of system parameters on the efficiency of supply chain.The article structure arrangement is as follows:In chapter 1,we introduce the research background and significance of supply chain operation efficiency and coordination optimization under carbon policy,and the study both at home and abroad,as well as the main research contents and innovative points in this paper.In chapter 2,we study the efficiency and coordination optimization of three-level supply chain,which the demand is not affected by the sale price.In the carbon trading policy,we analyze the optimal quantity,the optimal profit of the supply chain members under decentralized supply chain,considering the revenue sharing contract coordinat-ing perfectly three-level supply chain.At the same time,we analyze sensitivity of the parameter and relationship between the profit of each member in supply chain.In chapter 3,we study the efficiency analysis and coordination optimization of three-level supply chain,which the demand is affected by the sale price.In the carbon trading policy,we analyze the optimal quantity,the optimal profit of the supply chain members value under decentralized supply chain,considering the revenue sharing contract coordi-nating perfectly three-level supply chain.At the same time,we analyze sensitivity of the parameter and relationship between the profit of each member in supply chain to give reasonable suggestions.In chapter 4,we summarize the main conclusions and future prospects.
