研究由一个供应商和一个零售组成的二级供应链系统在碳税政策下的协调问题.对于市场需求率为时变函数且依赖于当前库存水平和销售价格的情形,建立分散式和集中式供应链决策模型.比较两种模型得出供应商和零售商合作能够提高供应链的整体利润但是也会产生更多的碳排放.分别利用批发价格契约和两部收费契约协调分散式决策模型得出供应链协调的条件.最后通过数值算例验证理论结果并分析碳税单价对供应链在两部收费契约下实现协调的影响.
To study the coordination problem of two-level supply chain system composed of one supplier and one retail under the carbon tax policy.For the case that the market demand rate is a time-varying function and depends on the current inventory level and the sales price, a decentralized and centralized Supply chain decision model.Comparison of the two models shows that the cooperation between suppliers and retailers can increase the overall profit of the supply chain but also generate more carbon emissions.By using the wholesale price contract and two charging contracts respectively to coordinate the decentralized decision model Finally, the numerical example is used to verify the theoretical results and analyze the impact of the carbon tax unit price on the supply chain coordination under the two toll contracts.
