Reliability and Mean Residual Life of Complex Systems With Two Dependent Components Per Element

The reliability and mean residual life of complex systems are discussed. These systems consist of
n
elements each having two
s
-dependent subcomponents. The reliability of such systems involves the distributions of bivariate order statistics, and are connected with a bivariate binomial distribution. The mean residual life function of complex systems with intact components at time
t
is also discussed. Some examples and graphical representations are given.
