This paper presents a holistic treatment to multiple dependent competing degradation processes, by employing the piecewise-deterministic Markov process (PDMP) modeling framework. The proposed method can handle the dependencies between physics-based models, between multi-state models and between these two types of models. A Monte Carlo simulation algorithm is developed to compute the components/systems reliability. A case study on one subsystem of the residual heat removal system (RHRS) of a nuclear power plant is illustrated.
