基于最小碳排放的绿色供应链网络设计模型研究

Study on Model of Green Supply Chain Network Based on Minimum Carbon Emissions

以多个厂商、多个配送中心和多个客户情况下的三层供应链网络为研究对象,提出了考虑碳排放成本的供应链网络设计模型,并利用Lingo9.0软件进行问题求解。将CO2排放量表示为货车行驶路程与运输途中载货量的函数整合进目标函数中,与只考虑开设配送中心的固定成本以及运输与配送成本的传统模型相比更具有现实意义。最后用算例进行了验证,对单位碳排放费用较高、较低以及不考虑碳排放成本的三种情况作了比较。

In this paper we studied the three-echelon supply chain network composed of multiple manufacturers, distribution centers and customers, proposed the supply chain network model based on cost of carbon emissions, and used the Lingo 9.0 software to solve it. At the end, we used a numerical example to verify the effectiveness of the model and compared the situations with high, low and irrelevant unit cost of carbon emissions.
