Reliability-centred maintenance (RCM) is a corporate-level maintenance strategy that is implemented to optimize the maintenance program of a company or facility. The final result of an RCM program is the implementation of a specific maintenance strategy on each of the assets of the facility.

Maintenance (RCM)

2. Maintenance : The Changing World
 Over the past 20 years, comparatively, maintenance
management changed than any other department.
 Due to the increment of number and variety of equipment
and complexity of designs leads to change the approach to
maintenance.
 Maintenance is also responding to changing expectation.
These include a rapidly growing awareness of the extent to
which equipment failure affects safety and the environment,
a growing awareness of the connection between maintenance
and product quality, and increasing pressure to achieve high
plant availability and to contain costs.

3. Reliability Centered Maintenance
(RCM)
 Failures have serious safety or environmental consequences, at a time
when standards in these areas are rising rapidly.
 Failures affect our ability to sustain satisfactory quality standards. This
applies as much to standards of service as it does to product quality. For
instance, equipment failures can affect climate control in buildings and
the punctuality of transport networks as much as they can interfere with
the consistent achievement of specified tolerances in manufacturing.
 Finally, the cost of maintenance itself is still rising, in absolute terms
and as a proportion of total expenditure. In some industries, it is now
the second highest or even the highest element of operating costs

TheFirstGeneration
•Fix it when broke
TheSecondGeneration
•Higher Plant

•Longer Equipment
Life
•Lower Cost
TheThirdGeneration
•Higher Plant

Reliability
•Greater Safety
•Better Product Quality
•No Damage to
Environment
•Longer Equipment life
•Greater cost

5. New Maintenance Approachs
TheFirstGeneration
• Fix it when broke
TheSecondGeneration
• Scheduled overhaul

• Systems for
planning and
controlling work
• Slow computers
TheThirdGeneration
• Condition

• Design for reliability
and maintainability
• Hazard studies
• Fast Computers
• FMEA
• Expert system
• Multiskilling and
teamwork

6. Challanges in Maintenance
 Selecting an appropriate technique to deal with different type of failure
 Most cost effective and enduring action to failure
 Active support and co-operation of all people involved

7. Maintenance Vs RCM
 Maintenance: Ensuring the equipment production without
downtime or optimum downtime
 RCM: Process that determine the maintenance requirements
of any equipment

8. RCM- Golden 7
 What are the function of the equipment and associated
performance of current operation?
 What are the ways to fail to achieve required performance?
 What are the causes of each performance failure?
 Define the effects of each failure?
 In what way does each failure matter?
 What are the ways to predict or prevent each failure?
 What should be done in case of no preventive action?

o Planning and Preparation
o RCM Analysis
o Implementation of Results
o Sustaining the Analysis
