Stochastic modelling of the joint effect of preventive and corrective maintenance on repairable systems reliability

The aim of this chapter is to propose a general model of the joint effect of corrective and preventive maintenance on repairable systems. The model is denned by the failure intensity of a stochastic point process. It takes into account the possibility of dependent maintenance times with different effects. The modelling is based on a competing risks approach. The likelihood function is derived, so parameter estimation and assessment of maintenance efficiency are possible.
