Method of fuse reliability evaluation based on small size of sample

A method of fuse reliability evaluation based on small size of sample was developed. Using the information coming from the simulation tests as the prior information of Bayes evaluation method, the size of sample could be reduced effectively. To deal with the problem of prior information fusion, the equivalent binomial data of the system were calculated by using equivalent-conversion and CMSR approaches. The correlation of binomial data with the data coming from the field test was analyzed and the inheritance factor was deduced, which would avoid the obliteration of field test information. The evaluation results of typical example show the feasibility and reasonability of the proposed method.
