RCM MethodologyThepractice of Reliability centered maintenance implements techniques such asPlanned Preventive Maintenance, Predictive Testing and Inspection, ReactiveMaintenance and Proactive Maintenance in a manner so as to augment the possibilitythat a component/equipment will operate in the requisite fashion over its intendedlife-cycle.

RCM entails that the maintenance decisions be founded onmaintenance requirements validated by sound scientific and financial rationale. Thecritical functions of any equipment or component to be safeguarded, withroutine maintenance tasks are ascertained along with their chief failure modesand causes. Consequences of these failures are also ascertained. The degree ofcriticality is ascribed to the outcomes of failure. Certain functions are not ofparamount importance, thus are allowed to “run to failure” whileother critical functions are protected. Maintenance tasks which address the primaryfailure causes are adopted. However, it is to be observed that this approach  can only address the failures that can beprevented, it certainly cannot guard against unforeseen circumstances or any arbitraryevents, etc.

Principles of Reliability CenteredMaintenance Thechief principles upon which Reliability Centered Maintenance is based are asfollows:·     RCM is function oriented: This primary aim of reliabilitybased maintenance is to protect the system and its function. ·     RCM is device group focused: RCM is predominantly concernedwith sustaining the overall functionality of a group of component rather thanan individual component ·     Fundamentally Reliabilitycentered: Thepractice of RCM gauges the relationship between the operating age and thefailures. RCM is not totally concerned with basic failure rate; it seeks to realizethe possibility of failure at specific ages. ·     Recognizes design limitations: One of the objectives of RCM isto sustain the innate reliability of the component design, recognizing thatchanges in reliability are more subject to design rather than maintenance.

Maintenance can only accomplish and maintain the level provided for by designof the component/equipment.RCM MethodologyThepractice of Reliability centered maintenance implements techniques such asPlanned Preventive Maintenance, Predictive Testing and Inspection, ReactiveMaintenance and Proactive Maintenance in a manner so as to augment the possibilitythat a component/equipment will operate in the requisite fashion over its intendedlife-cycle.
