چكيده فارسي :
Ageing concepts are important in reliability engineering. In this paper, we consider the ageing concepts of exponential lifetime random variable in the fuzzy environment. To this end, we consider two density functions which are based on the fuzzy parameter. Using these density functions, we define the survival, the hazard rate and the mean residual life functions.
