The Reliability Prediction of Component Cooling Water System (CCWS) Based on Copula

According to correlation between the equipment of CCWS, this paper uses Copula to describe correlation of the system, establishes the reliability prediction model of CCWS and does the quantitative calculation. Analysing the results shows that the reliability of redundancy system is much higher than that of single component, but dependent failures between the equipment decrease the reliability of system. And also shows that this model can be perfectly used in the reliability prediction of CCWS. CLC number: TL364+.1 Document id code: A
