Abstract—This paper describes the opportunistic maintenance model for availability analysis of two component series system using the Markov and the Monte Carlo Simulation methods. The system model is developed incorporating four states for each component considering their level of degradation. Separate models are developed for three cases of corrective repair such perfect, imperfect, and minimal repair with and without condition based opportunistic maintenance. These models are solved using analytical Markov approach. The solutions are validated by the Monte Carlo Simulation. Since the Markov approach is limited to exponential failure and repair rates, the Monte Carlo Simulation based codes can be further extended to accommodate systems which follow non-exponential failure and repair rates.
