摘要:针对小子样悪维修怱性验悚证试验悚方法进行研悁究。首先,采用 Matlab 工具箱中的秩和方法对验悚前数据进行一惊致
性检验悚,再使用基于权重因愁子的信息融合方法确定混合验悚前分布,最后,运用概率似然比方法得出混合验悚前分布下
的小子样悪维修怱性验悚证试验悚方案。实例证明,该方法可以惣减少现场试验悚样悪本量,降低试验悚费用,缩短试验悚周期,提高
军事经济效益惵。

Abstract: Research on method of small sample maintainability verification test. Firstly take the prior data into identity
check by use of rank test in Matlab toolbox; Secondly use the method of information amalgamation based on weighting
factor to confirm the mixed prior distribution; Finally will get the scheme of small sample maintainability verification test
based on the mixed prior distribution by use of probability likelihood radio method. Examples show that the method can
reduce the field test sample size, lower test cost and shorten the test cycle, to improve military economic benefit.
