【Abstract】 Owing to the gigantic economical value in exploiting a few samples system of the reliability tests used for the complicated mechanical systems a new method was set up. This method combined the advantages of the probability and the fuzzy mathematics, and exploited the unknown system of a few samples with help of the life samples of the known probabilistic distribution,which reduced the test samples by some auxiliary information. It also converted the reliability tests into a few samples and green tests for resources. Two engineering examples are introduced in the article.更多还原
