Abstract : The report develops methods for estimating the probability that an aeronautical equipment will operate satisfactorily for the duration of a specific mission. The failure times are modeled by exponential and Weibull densities. The parameters are estimated from multiple independent grouped and censored samples. Several estimation methods are developed for each model. In addition, the equations to obtain maximum-likelihood estimates are derived. However, they would have to be solved iteratively. Monte Carlo simulation is used to compare estimates with the data grouped and with the failure times known. (Author)
