摘要：

There is epistemic uncertainty in degradation law of a high-reliability component because it is hard to obtain its adequate performance data within a short time, and system reliability cannot be accurately estimated. For the purpose of accurate estimation of system reliability, assuming that the component performance distribution parameter was the interval variable, a component' performance parameter distribution model was built based on interval parameter variable and a computational method of the interval-valued state probability was provided. The boundary of the state performance interval was compensated, the interval-valued universal generating function and its algorithm were defined, an assessment method of interval-valued reliability of the multi-state system in consideration of epistemic uncertainty was proposed, and the reliability of a power amplification system was analyzed. This method not only avoids the lack of distribution information of the performance parameters, but also accurately builds a distribution model of the performance parameters. Therefore, it is widely used in engineering. © 2016, Editorial Board of JBUAA. All right reserved.
