Real life time data are usually more or less fuzzy. Therefore it is necessary to generalize statistical estimation of the reliability characteristics. For life time data in form of fuzzy numbers x* with characterizing function ξ(.) this is possible and explained in the paper. Especially classical parameter estimations for stochastic life time models and the concept of the empirical reliability function as well as Bayesian reliability estimation procedures are generalized. Moreover the important technique of accelerated life testing is revisited in face of non-precise observed life times.
