中文摘要：

提出了一种考虑客户满意度的电动汽车充电站运营状态评估方法。首先运用DS/G2法将客户对电动汽车充电站语言服务评级和充电站运行状况信息进行证据融合,以确定单个客户对某一电动汽车充电站的运营状态评估结果量化值;然后引入证据冲突的概念,对多个客户评估结果量化值的权重进行综合优化,基于D-S证据理论融合多个客户的评估结果,对多个充电站的运营水平进行比较。算例验证了该方法的可行性。

英文摘要：

A method of operating state evaluation considering customer satisfaction is presented for EV（Electric Vehicle） charging station. The evidences of an EV charging station,such as its operating states and the linguistic assessments of its services by a customer,are integrated based on the DS / G2 method for obtaining his quantified evaluation of its operating states. The concept of evidence conflict is introduced to synthetically optimize the weights of various customers＇ evaluations. Multiple customers＇ evaluations are fused based on the D-S evidence theory for comparing the operational level among multiple charging stations. The feasibility of the proposed method is verified by the example.
