Performance Assessment Model for Highway Electromechanical System

Based on the research of the law of performance of electrical and mechanical equipments, the characteristics of highway electromechanical system is studied. According to current quality inspection and evaluation standards, the hierarchy criteria system is deduced, and the importance degree of each criterion is calculated according to the responses on the question form by Delphi method. By membership functions, each criterion is given the weight which is normalized as the importance degree for the hierarchy level. Then, the fuzzy comprehensive assessment model is established with judgment matrix.
