RCM Methodology

The
practice of Reliability centered maintenance implements techniques such as
Planned Preventive Maintenance, Predictive Testing and Inspection, Reactive
Maintenance and Proactive Maintenance in a manner so as to augment the possibility
that a component/equipment will operate in the requisite fashion over its intended
life-cycle. RCM entails that the maintenance decisions be founded on
maintenance requirements validated by sound scientific and financial rationale.

The
critical functions of any equipment or component to be safeguarded, with
routine maintenance tasks are ascertained along with their chief failure modes
and causes. Consequences of these failures are also ascertained. The degree of
criticality is ascribed to the outcomes of failure. Certain functions are not of
paramount importance, thus are allowed to “run to failure” while
other critical functions are protected. Maintenance tasks which address the primary
failure causes are adopted. However, it is to be observed that this approach  can only address the failures that can be
prevented, it certainly cannot guard against unforeseen circumstances or any arbitrary
events, etc.

Principles of Reliability Centered
Maintenance

The
chief principles upon which Reliability Centered Maintenance is based are as
follows:

·     
RCM is function oriented: This primary aim of reliability
based maintenance is to protect the system and its function.

 

·     
RCM is device group focused: RCM is predominantly concerned
with sustaining the overall functionality of a group of component rather than
an individual component

 

·     
Fundamentally Reliability
centered: The
practice of RCM gauges the relationship between the operating age and the
failures. RCM is not totally concerned with basic failure rate; it seeks to realize
the possibility of failure at specific ages.

 

·     
Recognizes design limitations: One of the objectives of RCM is
to sustain the innate reliability of the component design, recognizing that
changes in reliability are more subject to design rather than maintenance.
Maintenance can only accomplish and maintain the level provided for by design
of the component/equipment.
