Resumo
While there have been many improvements and enhancements to traditional reliability-centered maintenance (RCM), one of the improvements that has not been widely implemented is the use of risk in the RCM process. The experience of the writers with RCM analyses has shown that using risk-based decision-making tools can improve decisions made during the RCM analysis. This occurs because risk is a more direct measure of the loss associated with each failure mode (e.g., production loss, etc.), thereby, providing the analysis teams with the information needed to better determine: Which units/systems/subsystems within a facility represent the best opportunities for improvement? What maintenance strategies are needed to achieve an acceptable level of performance (i.e., acceptable level of loss exposure)? Whether implementation of the selected maintenance strategies is justified (i.e., is the cost of implementing the strategy justified based on the reduction in loss exposure?) Risk-based RCM is a hybrid RCM approach that integrates risk-based decision tools and the fundamentals of the traditional RCM analysis process into a single analysis process. This approach is based on the use of proven risk-based decisions tools and is consistent with the requirements in the Society of Automotive Engineers (SAE) draft standard on RCM (JA SAE 1011). This paper provides an introduction to RCM; an overview of risk; and describes an RCM process that incorporates these risk-based decision tools.
