A study on Bayesian method for reliability evaluation of small sample size aviation support systems

In order to realize the reliability evaluation of small sample size aviation support system with known prior information, Bayes methods are given by using second-order moment equivalent method, relative least squares method (RLS method), maximum entropy (ME method) and Chebyshev polynomial respectively, accuracies above synthesis compared analysed through an example. The results show that ME RLS have higher accuracy than expansion method. Finally, applied system, good obtained. At same time, it provides a valuable reference for complex in engineering practice.
