在考虑供应链中核心制造商所在的市场有碳排放约束以及碳可交易机制的前提下,研究了三级绿色供应链中,当上游供应商的绿色水平影响核心制造商的碳排放量时,供应链上各个环节的最优策略。并分别给出了分散决策和集中决策下供应链的最优订购量、制造商的最优绿色减排水平以及供应商的最优绿色水平,同时对影响决策的各个因素进行了分析。比较了分散决策和集中决策模式下绿色供应链与传统供应链碳排放量的大小。结果表明,两种决策模式下,碳排放量约束和碳可交易机制都有可能会使得绿色供应链的碳排放量大于传统非绿色供应链。最后,通过数值试验研究了市场对绿色产品的敏感程度和具有不同属性的产品对供应链总利润以及碳排放量的影响。
Under the premise of considering carbon emission constraints and carbon trading mechanism in the market where core manufacturers are located in the supply chain, when the green level of upstream suppliers affects the carbon emissions of core manufacturers in the tertiary green supply chain, The optimal strategy of every link in the supply chain. The optimal order quantity of supply chain, the optimal green emission reduction of manufacturer and the optimal green level of supplier under decentralized and centralized decision-making are respectively given. At the same time, the various factors influencing decision-making are analyzed. Compares the carbon emissions of green supply chain and traditional supply chain in decentralized and centralized decision-making. The results show that under the two decision-making modes, the carbon emissions constraint and carbon trading mechanism are likely to make the carbon supply of green supply chain more than the traditional non-green supply chain. Finally, we study the market sensitivity to green products and the impact of products with different attributes on total supply chain profit and carbon emissions through numerical experiments.
