Abstract
The expressway electromechanical device comprehensive maintenance is essential maintenance work. The scientifically evaluation on the comprehensive maintenance efficiency is very important to the expressway electromechanical device management office. Set pair analysis method is used to maintenance support evaluation. Firstly, the paper designed the evaluation index system of the expressway electromechanical device comprehensive maintenance. Secondly, the evaluation model of the comprehensive maintenance efficiency based on the set pair analysis method is built. Then the application steps of the set pair analysis method are introduced. At the end of the paper, a real application example is given. The results of the application indicated the model is feasible and effective. It can give strong support to improve the evaluation effect of the expressway electromechanical device maintenance support.
