考虑CO_2排放量的城市专业物流中心选址研究

The Location of City Professional Logistics Centers on Consideration of CO_2 Emissions

目前关于物流中心选址的研究多基于企业的角度,鲜有学者站在地方政府角度考虑不同行业物流特点对城市物流中心选址进行研究。本文基于钢材分销行业特征,从地方政府角度出发,构建了综合考虑CO2排放量和物流成本的双目标整数规划模型,采用理想点法将双目标转化为单目标并用分枝定界法对该模型进行求解。本文以重庆市钢材分销行业的城市物流中心选址为例进行分析,并将CO2排放量的测算结果以澳大利亚碳税的征收标准进行计算,发现碳税征收并不能有效降低钢材行业CO2排放量。地方政府可通过合理选择物流中心位置、规范城市物流配送车辆选型、限速、限行和错峰限时等城市物流管理策略来实现低碳物流。

Plenty papers study logistics center location problems based on the perspectives of enterprises. While few scholars consider impacts of local government and logistics characteristics of different industries. Based on the logistics characteristics of steel distribution industry, a dual-objective integer-program- ming model is constructed both considering CO2 emissions and logistics costs, which represents the opinions of local government. Then doubles goals model are turn into a single one model by ideal point method. The logistics center location problems of Chongqing steel distribution industry is taken as an example, and the results of logistics center locations are obtained through collecting and computing the real data from Chongqing steel distribution industry. At last tax of CO2 emissions is calulated based on the standard of carbon tax in Australian. Results show that tax of CO2 could not reduce CO2 emissions effectively. Local government should adopt other City logistics methods to control CO2 emissions effectively, such as reasonable location of logistics center, vehicle selection, speed limit, time windows and so on.
