Research on Fault Diagnosis of Complex System Based on Bayesian Network

Abstract

The Fault tree analysis has large limitations in the application of complex fault diagnosis system, which is difficult to solve complex system fault diagnosis polymorphism exhibited events, uncertainty of information, failure logical relationship and other issues, this paper presents a novel Bayesian network method , which can solve these problems better. This paper is taking an example of faulting diagnosis of the fan system to verify the effectiveness of this new method.
