Abstract: Abstract Generally modelling lifetime data is carried out using probability distributions with the aid of reliability functions such as hazard rate, mean residual life, etc. In the present work an alternative approach is proposed by considering bivariate copulas instead of bivariate distributions. We define the analogues of reliability functions that are expressed in terms of copulas and study their properties. The results of the study are applied to case of the copulas of a bivariate exponential family of distributions.
