Research on Evaluation Method of Mechanical and Electrical System

A new method of health states assessment based on fuzzy comprehensive evaluation and entropy weight DSmT was proposed in this paper, Firstly, each index relatively objective entropy weights are determined. Then get the basic belief assignment of each index through the method of fuzzy comprehensive evaluation, and combine the above results using entropy weight DSmT. Finally, use the new method to evaluate a power supply system. The results indicated that the proposed method can get good efficiency for the accurate rate increased 13.5% compared with DSmT fusion.
