Optimal Decision Making In The Three-level Supply Chain Under The Carbon Labeling System

The carbon labeling system is a policy that integrates government constraints and market mechanisms to reduce carbon emissions.Under the carbon labeling system,how the supply chain system can reduce carbon emissions and make supply chain decisions to deal with increasingly serious environmental problems have become an urgent issue.Through literature review,most of the current researches focus on the emission reduction decisionmaking of the three-level supply chain,and there are few studies on the twolevel supply chain.This paper analyzes decision-making and coordination management of the three-level supply chain under the carbon labeling system.The research content and main conclusions of this article are summarized as follows:(1)Study the decision-making optimization problem of the three-level supply chain under the carbon labeling system.First,a three-level supply chain composed of a supplier,a manufacturer and a retailer is constructed,and the optimal pricing,optimal carbon emissions,and optimal product sales under decentralized scenario,collaborative scenario and centralized decision-making scenario are studied.On this basis,analyzes the impact of consumers’ lowcarbon preferences on the total carbon emissions of the supply chain,and compares the optimal decisions of these four decision-making scenarios.(2)Study the profit distribution of the three-level supply chain under the carbon labeling system.First,compare the total profit of the supply chain in the different scenarios and find that the total profit of the supply chain is the largest under centralized decision-making when c2<1.1bβ.On this basis,the profit of the alliance under different decision-making situations is distributed based on Shapley value and AT solution respectively,the results show that the Shapley and the AT allocation results are consistent under collaborative decision-making.(3)Numerical analysis is carried out on the research of the first two chapters.Visually analyze the impact of consumers’ low-carbon preferences on the total carbon emissions of the supply chain and the comparison of the optimal decisions in various decision-making scenarios.In addition,through numerical verification of the allocation results based on Shapley value and AT solution,the results show that the enterprises will eventually choose centralized decisionmaking.The result of the AT solution is further compared with the result of the Shapley value to illustrate the applicability of the AT solution to the profit distribution problem with restricted alliance structure.The main contributions of this paper are as follows:(1)study the decisionmaking optimization and coordination management of the three-tier supply chain under the carbon labeling system,which is different from the previous second-tier supply chain carbon emission reduction issues,and also provides a theoretical reference for the decision-making of supply chain members in reality;(2)a comparative study of the profit distribution by Shapley value and the AT solution,thereby explaining the applicability of the AT solution to the profit distribution problem with restricted alliance structure.
