摘要
研究了系统中由于元素状态概率的不同表示法而产生的不确定性 ,在LevV .Utkin提出的不确定性重要度算法基础上 ,提出了一种新的不确定性重要度算法 ;并利用这种算法扩展了LevV .Utkin的元素不确定性重要度归一化算法 ,为存在着多种状态概率表示方法的大型、复杂的工程系统提出了系统可靠性的归一化算法·
The uncertainty in the estimation of system reliability in the stochastic,fuzzy,and interval forms was studied. A new unified means to estimate system reliability was developed for three forms of probability description. A new means to calculate uncertainty importance and to improve unified means to estimate system reliability were proposed based on the uncertainty importance arithmetic by Lev V. Utkin.
