基于多层次灰色评价方法的新能源电动汽车充电设施选址的研究

Site Selection of Charging Infrastructures for New Energy Electric Vehicles Based On Multilevel Grey Evaluation Method

为了保护生态环境,使用新能源电动汽车的人越来越多,配套的充电设施建设迫在眉睫。针对新能源电动汽车充电设施选址问题,本文通过建立新能源电动汽车充电设施选址评价指标体系,采用多层次灰色评价方法和符号计算软件Mathematical确定各层评价指标的权重,构建了新能源电动汽车充电设施选址问题的多层次灰色评价模型,并用实际算例进行了评价研究,该模型有效的解决了新能源电动汽车充电设施的选址问题。

To protect the ecological environment,new energy electric vehicles were widely used,which entailed construction of supporting charging facilities.As for the siting of charging stations,an evaluation index system was established,where a multilevel grey evaluation method and the symbolic computation software,Mathematica,were used to determine the weight of each evaluation index.Also,a multilevel grey evaluation model for the siting of the new energy electric vehicle charging stations was developed and it was evaluated with practical examples.This model can effectively solve the siting problem of charging stations for the new energy electric vehicles.
