Abstract: Restoration of initial operational availability of the system in a cost effective way is the main objective of reliability centred maintenance. It is used to optimise preventive maintenance strategies. In this paper, reliability centred maintenance is applied to a real-time case and suggested cost effective maintenance tasks for the most critical component of the system, which is identified by using Ishikawa diagram and failure mode effect and criticality analysis (FMECA). The decision tree is used to suggest cost effective maintenance tasks for the critical component. The inherent and operational availability of the system is estimated by determining two important reliability parameters, mean time between failure (MTBF) and mean time to repair (MTTR). These parameters are determined by using Monte Carlo simulation and continuous Markov chain respectively.

Keywords: reliability centred maintenance; RCM; availability; failure mode effect and criticality analysis; FMECA; mean time between failure; MTBF; mean time to repair; MTTR; simulation; Markov chain analysis.
