The 2–parameter Weibull model can be re–parameterized in terms of shape parameter and a prefixed age for which a reliability estimation is required. Using the uniform and beta priors, some new point and lower bound reliability estimators were derived. These estimators appear to be very suitable to meet the needs of fast and cheap reliability evaluation during production. Their characteristics were studied by means of a Monte Carlo simulation and were compared with those of the maximum likelihood estimators.
