✦ Synopsis

The paper & concerned with the analysis of a repairable system's failure behaviour. In a brief survey the shortcomings of commonly used probabilistic models are mentioned. Appearing to be more appropriate, a regression type of analysis is followed, with explanatory variables acting additively on the hazard function. As repairable systems may experience multiple failures, the hazard function modelling is continued beyond a system's first failure to second and subsequent failures. In this way a kind of additive variant of the model developed by Prentice, Williams and Peterson (which is an extension of Cox's proportional hazards model) is formulated. The techniques are illustrated in an example.
