A bivariate competing risks problem is considered for a rather
general class of survival models. The lifetime distribution of
each component is indexed by a frailty parameter. Under the
assumption of conditional independence of components the
correlated frailty model is considered. The explicit asymptotic
formula for the mixture failure rate of a system is derived. It is
proved that asymptotically the remaining
lifetimes of components tend to be independent in the defined
sense. Some simple examples are discussed.
