The alert-delay competing risks model for maintenance analysis
Résumé
The paper considers the modelling of the dependency between corrective maintenance and condition-based preventive maintenance of complex repairable systems. A new model of dependent competing risks is proposed, called the Alert-Delay (AD) model. This model has different properties from that of the Delay-Time and Repair-Alert models and happens to fit some data sets which could not be fitted by the previous models. The main features of the AD model are derived: probabilistic properties and statistical analysis. Simulation results and an application to real data are presented.
