D-S Evidence Theory Information Fusion Methods and Applications

In this paper, a D-S evidence theory information fusion method is proposed along with the basic concept of D-S evidence theory and the synthesis law. By applying this information fusion method to the condition monitoring of generating units through simulation experiments, the real-time operating status of the units can be reflected from different aspects, and a comprehensive and correct understanding of the environment or characteristics can be derived to make more accurate and complete estimates and decisions, thus improving the robustness of the whole system. From the experimental results, it can be seen that the D-S evidence theory information fusion method effectively reduces the uncertainty of fault diagnosis and improves the credibility of fault state identification.
