Cost-optimized scheduled maintenance interval for reliability-centered maintenance

Implementation of a reliability-centered maintenance program is based on performance of proactive maintenance actions that serves to preserve system functionality. Predictive maintenance is a recognized proactive maintenance action that has been underutilized due to quantitative complexity and to the lack of a constraint that defined an optimum scheduled maintenance interval. A cost-optimized scheduled maintenance interval is proposed that uses costs as the constraint and overcomes quantitative complexity by use of current computer and software technology. Combined with condition-based monitoring the cost-optimized scheduled maintenance interval enables an organization that owns and operates fleets of assets to implement a comprehensive reliability-centered maintenance program.
