针对确定需求闭环物流网络中工厂和配送中心的两级选址问题，建立了以最小总建设和运营成本、最优客户时间满意度以及物流网络低碳为目标的多目标混合整数规划模型。通过引入模糊数学中的隶属度概念，将复杂的多目标规划转换为单目标规划，确定了不同目标权重下工厂和配送中心的位置、数量，构建了考虑碳排放的多目标闭环物流网络。研究表明：不同单目标下选址结果有明显的差异；各目标权重变化对选址结果有明显的影响。

T his paper develops a multi-objective mathematic model for the location of plant sites and distribution sites for closed-loop logistics network under certain demands .One objective of our model is to minimize the total cost of construction and operation .And the other two objectives are to satisfy requirements of time and low-carbon .Based on membership degree of fuzzy mathematics ,a multi-ob-jective functions is put into a simple single objective problem .Through solving the model ,the loca-tions and numbers of these sites in different weights can be determined .Therefore ,a multi-objective closed-loop logistics network is constructed .Research shows that the location results have obvious differences under different single objective ;every target weight change has obvious influence on the location results .
