"Weibull models appear to be very flexible and widely used in the maintainability field for ageing models. The aim of this contribution is to systematically study the ability of classically used one-mode Weibull models to approximate the bathtub reliability model. Therefore, we analyze lifetime data simulated from different reference cases of the well-known bathtub curve model, described by a bi-Weibull distribution (the infant mortality is skipped, considering the objective of modeling ageing). The Maximum Likelihood Estimation (MLE) method is then used to estimate the corresponding parameters of a 2-parameter Weibull distribution, commonly used in maintenance modeling, and the same operation is performed for a 3-parameter Weibull distribution, with either a positive or negative shift parameter. Several numerical Studies are presented, based first large and complete samples of failure data, then a censored data set, the failure data being limited to the useful life region and to the start of the agein"@en . .
