基于Bayes可靠性评估验前信息检验方法的研究

Test Method of Prior Information Based on Bayes Reliability Evaluation

在使用Bayes方法对系统进行可靠性评估过程中,需要对系统可靠性的验前信息进行可信性检验。先验信息的检验方法可以分为参数检验方法和非参数检验方法,本文主要对非参数检验方法进行了介绍和研究。非参数检验方法中,本文针对验前信息样本量的大小分别介绍研究了Kolmogorov-Smirnov检验、皮尔逊χ2检验和Wilcoxon秩和检验等几种较为常用的检验方法。

The prior information of reliability need to be tested for creditability in the reliability evaluation using Bayes method. There are two kinds of test method of prior information :parameter test method and non-parameter test method,in this paper,the non-parameter test method is mainly introduced and studied. In the paper,Smirnov test,Pearson test and Wilcoxon rank test are studied.
