Reliability Centered Maintenance (RCM) is the process used to determine the maintenance strategy to be applied to increase the likelihood that your company’s assets function optimally over the design lifecycle in the most cost-effective manner.
The outcome of the RCM is the implementation of any of Preventive Maintenance (PM), Predictive Maintenance (PdM), Run-to-Failure (reactive maintenance) and Proactive Maintenance strategies on each of your company’s assets.
Overall, the objective of RCM is to ensure that your company’s maintenance program achieves high levels of operational readiness, safety, environmental soundness, and reliability at low cost.
These core principles guide the RCM process:
The outcome of an RCM is three maintenance tasks:
The reliability centered maintenance considers the reliability of assets in a facility based on the answers to the following critical questions:
Reliability-centered maintenance facilitates your company’s capabilities to minimize system failures, increase asset reliability and availability to meet set KPIs. It prioritizes assets that are most likely to fail, fails frequently, or with a devastating consequence of failure. Then subject such assets to cost-effective maintenance tasks that cut down the likelihood of failure.
By implication, RCM reduces maintenance cost and increase asset uptime.
However, RCM is disadvantaged when the process fails to consider the cost of acquiring and maintaining an asset.
The various approaches to RCM have the following vital steps in common:
