According to the characteristics of a charging network system, an overall target to be achieved by comprehensive evaluation is decomposed into several main decision factors, detailed index refinementis carried out, detailed definition and calculation methods of all indexes are provided, and an analysis model of a hierarchical structure is formed; according to different index properties, a direction processing method suitable for charging network operation evaluation indexes is provided for a reverse type, an interval type and an intermediate type. The weight w of the bottom-layer index for the highest-layer total target is determined by using an analytic hierarchy process, and a comprehensive evaluation result of each station operation condition participating in evaluation is obtained bycombining the calculation of the cosine distance of the TOPSIS method. According to the method, the advantages of the subjective method and the objective method are fully integrated, the obtained evaluation result is more accurate and objective, and the method has the characteristics of systematicness, flexibility, convenience, qualitative and quantitative combination and high implementation feasibility.
