需求不确定条件下低碳供应链网络设计研究

不同的碳排放约束会对供应链网络设计的选址及工厂环保等级的选择产生影响。文中综合考虑环境投资决策、网点选择以及路径的选择等问题,以总运作成本、生产和运输途中碳排放量最小为目标,建立不同需求情境下、需求不确定的多产品双目标混合整数规划模型,结合ε约束法设计了基于情景的求解算法。最后通过算例分析,验证模型和算法的有效性。

Low Carbon Supply Chain Network Design under Demand Uncertainty

Different carbon emissions constraints have an effect on the site selection of supply chain network design and the selection of factory environmental protection level. In consideration of the environmental investment decision,network selection and routing selection,a multi- products and bi- objectives mixed- integer programming model,which targets in the minimum of total operation cost and carbon emissions in production and transit,is constructed with different demand scenario and demand uncertainty. A scenario- based algorithm is designed with ε restriction method. The proposed model and algorithm are verified by the example.
