Reliability Evaluation Based on Uncertain Bayesian rule
Authors: ,
Abstract: This paper focuses on the reliability evaluation of a one-unit system based on uncertain Bayesian rule, in which the unit’s lifetime is assumed to be an uncertain variable. Considering two types of the posterior uncertainty distribution of the lifetime, the Bayesian estimation method of uncertainty parameter is first proposed. Then reliability evaluation is carried out by calculating uncertainty reliability R(T) with a specific time T and mean time between failureMTBF. Finally, some numerical examples are conducted to illustrate the application of the new method.
