Abstract

Fitting models to failure data is an important topic in reliability. The resulting models can be useful both for manufacturers as well as for end-users. In this paper we provide details of some methods from the literature which can be used as a starting point when analysing and fitting models to failure data from repairable items. In particular we focus on obtaining analytical estimates of the intensity of a non-homogeneous Poisson process. We illustrate some of these methods on failure data from the warranty database of a major car manufacturer.
