Reliability Centered Maintenance (RCM)

Reliability centered maintenance (RCM) is a systematic, disciplined process to ensure safety and mission accomplishment through assurance of continuity of system functions. RCM process defines: system boundaries and identify system functions, functional failures, and likely failure modes for equipment and structure in a specific operating context. RCM develops a logical identification of the cause and effect and functional failures to arrive at what maintenance task to perform to assure the applicable and cost effective management strategy to reducing the probability of functional failure and associated risk in present operating context. RCM combines some other maintenance procedures resulting in a more reliable strategy. RCM produce task list that contain risk priority number (RPN) and different maintenance methods applicable to facility equipment/components, such as preventive maintenance, predictive maintenance, and run to failure. 


Benefit of RCM

a. It decreases equipment and component failure and increase MTTF/MTBF. 

b. It can identify failure potential mode and hidden failure earlier. 

c. It increases maintainability (reduce MTTR). 

d. It increases availability and decrease unplanned shutdown. 

e. It decreases maintenance cost. 

f. It optimizes spare parts /stocking management. 

g. It improves safety of people and asset.
