摘要
在小样本情况下,利用数理统计方法来确定航空设备的寿命分布类型是不太适用的,本文运用模糊综合评判方法综合经验信息来确定先验分布,同时运用贝叶斯理论将统计推断建立在后验分布的基础上,给出了一种有小样本试验数据确定寿命分布的可靠性方法。
In a small sample, it is not applicable to determine the type of life-distribution of aviation equipment with mathematical statistical methods. This paper proposes a method for determining life reliability model using data of small sample experiment. In the method, the fuzzy synthesis judgment is used to consider empirical information and determine empirical distribution, and the Bayes theory is used to establish the foundation of statistical inference.
