School of Electrical Engineering, Southw est Jiaotong University, Chengdu 610031, China; 2. China Railw ay Eryuan Engineering Group Co. , Ltd. , Chengdu 610031, China) Abstract: The scheme choice of traction pow er supply in electric railw ay concerns many qualitat ive and quantitative factors, and is a complex and fuzzy multiple attribute decision problem. Based on design principle of tract ion power supply system, the layer index system for scheme optimization is established. An improved comprehensive evalua tion method based on analytic hierarchy process (AH P) and technique for order preference by similarity to ideal so lut ion (T OPSIS) is presented. First, the index w eight is calculated by the definition of the attribute significance based on the w eighted sum. Then, the aut horit y and decision consistency of experts are unif ied by group decision making . Finally, vert ical distance is proposed and the order of priority of all schemes is given according to it. Tak ing an under construction passenger dedicated line for example, the analysis show s t hat the method feat ures clear theory and bett er generality , it is an efficient decision method used in scheme optimization of traction power supply.
