A study of Availability-Centered Preventive Maintenance for Aging Multi-state K-out-of-N Systems
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 12
Abstract
This study focuses on the aging multi-state k-out-of-n systems to establish a practical preventive maintenance (PM) model from the perspective of components. The established PM model aims to maximize system availability subject to total maintenance cost. Non-homogeneous continuous time Markov models (NHCTMMs) are utilized to evaluate the system availability, and using non-homogeneous continuous time Markov reward models (NHCTMRMs), to evaluate the total maintenance cost. The system availability and total maintenance cost for PM policies are substituted into a genetic algorithm (GA) to optimize the established PM model. A simulation case with the sensitivity analysis conducted verifies the efficacy of the proposed approach.
