面向碳减排投资优化的低碳供应链网络设计及优化研究

Carbon Emissions Reduction and Investment Optimization Oriented Design and Optimization of Low-carbon Supply Chain Network

研究了低碳经济背景下供应网络的设计和优化问题,考虑了供应链网络中各节点企业碳减排效率及减排收益的内在差异性,以及由此产生的碳减排投资边际效益的差异性。以供应链网络的环境绩效和经济绩效为目标建立了一个双目标规划模型,模型综合考虑了碳减排投资的优化配置、网点的选择以及运输路径、方式的选择等问题,最后,通过对算例的求解研究,探讨了碳减排投资的优化配置问题及低碳对供应链网络结构的影响。

In this paper, we studied the design and optimization of supply chain networks in the low-carbon economy, environment, amidst which we considered the efficiency of the nodal enterprises in the networks in carbon emissions reduction, the internal difference in the benefit of the emissions reduction, as well as the difference in the marginal benefit of the resultant investment to reduce carbon emissions. Then with the environmental performance and economic performance of the supply chain networks as the objectives, we built a dua-objective programming model to comprehensively study the problems of optimzed configuration of carbon-emissions-reduction oriented investment, selection of network nodes as well as of route and method of transportation, etc. At the end, through a numerical example, we discussed the influence of the optimized investment configuration on the low-carbon development and the structure of the supply chain networks.
