چكيده لاتين :
The useful period of lifetime distributions with bathtub-shaped failure rate functions has attracted authors and researchers in reliability, actuary, and survival analysis. The flat region of failure rate function should be long to have a useful unit with corresponding distribution function. In this paper we investigate the difference between the change points of failure rate and mean residual life functions of some generalized gamma, type distributions due to the capability of these distributions in modeling various bathtub-shaped failure rate functions.
