Research on reliability analysis of plane power supplying system based Bayesian fusion

Reliable operation of the aircraft power distribution system is critical to the flight safety of a plane. In this paper, the reliability evaluation model of aircraft power supplying system based on Bayesian fusion is set up. Calculating reliability indexes by using MATLAB simulation softwaer. Comparing with the traditional Bayes approach, the result shows the method is efficient. For avionics products reliability assessment are mostly small sample size problem. In case of lack of field test data, Take full advantage of the reliability of information to assess its reliability, Bayes method is a more effective method. This paper introduces the inheritance factor, integrating two types of information into a hybrid priori With the principle of information fusion. It is further assumed inheritance factor is a random variable, Finally, a comparison shows that the method in this paper is more reasonable and valid than The first two methods by simulation.
