Reliability Centered Maintenance

Reliability Centered Maintenance (RCM) is a technique for analyzing and optimizing maintenance strategies. It incorporates methods such as Failure Mode Effects and Criticality Analysis (FMECA). The main objectives of Reliability Centered Maintenance are:

The Reliability Centered Maintenance process begins with a FMECA that identifies the importance of plant failure modes in a systematic and structured way. The process then requires the examination of each critical failure mode or cause to determine the optimum maintenance policy to reduce the severity or occurence of each failure.

The chosen reliability and maintenance strategy must take into account cost, safety, environmental and operational consequences. The effects of redundancy, spares costs, maintenance labor costs, equipment ageing and repair times must also be considered.

When optimal maintenance policies have been decided and recorded the RCM process provides system performance predictions and costs, expected spares requirements and labor manning levels.
