Maintenance management involves keeping equipment running at high capacity and low cost through a set of organized activities. The objectives of maintenance include efficient use of personnel, maximizing equipment life, reliability, quality, safety and minimizing costs and interruptions. There are various types of maintenance like preventive, corrective, and predictive. Preventive maintenance involves scheduled, running and shutdown maintenance to prevent failures. Corrective maintenance repairs equipment after failure through breakdown or shutdown maintenance. Predictive maintenance predicts failures through condition monitoring.

1. Maintenance Management

3. Maintenance Management
 Modern maintenance management is
not to repair broken equipment rapidly.
Modern maintenance management is to
keep the equipment running at high
capacity and produce quality products at
lowest cost possible.
 Maintenance is a set of organized
activities that are carried out in order to
keep the item in its best operational
condition with minimum cost required.

4. Maintenance Objectives
 Efficient use of maintenance personnel and
equipments.
 Maximize useful life of equipment
 To increase functional reliability of production
facilities.
 To enable desired quality through correctly
adjusted, serviced and operated equipment's.
 To maximize the useful life of equipment's.
 To minimize cost of production.
 To minimize frequency of interruptions.
 To enhance the safety of manpower.

5. Areas of maintenance management
Civil Maintenance
Mechanical maintenance
Electrical Maintenance

6. Impact of Poor Maintenance
1. Production capacity:
 Machines idled by breakdowns cannot produce,
thus the capacity of the system is reduced
2. Production costs:
 Labor costs per unit rise because of idle labor due
to machine breakdowns. When machine
malfunctions result in scrap, unit labor and material
costs increase.
3. Product and service quality:
 Poorly maintained equipment's produce low quality
products. Equipment's that have not been properly
maintained have frequent break downs and cannot
provide adequate service to customers.

7. CONT…
4. Employee or customer safety:
 Worn-out equipment is likely to fail at any
moment and these failures can cause injuries to
the workers, working on those equipments.
Products such as two wheelers and
automobiles, if not serviced periodically, can
break down suddenly and cause injuries to the
stress
5. Customer satisfaction:
 When production equipments break own,
products often can not be produced according
to the master production schedules, due to work
stoppages. This will lead to delayed deliveries of
products to the customers.

9. planned maintenance
In planned maintenance the
maintenance action is carried out with
some fore thoughts, prior planning ,
record keeping and control action.
These can be further classified as :-
Preventive maintenance
Corrective maintenance
Predictive maintenance

10. A: Preventive maintenance
 It is based upon the principle that ‘prevention is better than
cure’.
 Involves performing maintenance activities before the
equipment fails.
 It is a set of activities that are performed on plant
equipment, machinery, and systems before the occurrence
of a failure in order to protect them and to prevent or
eliminate any degradation in their operating conditions.
 Or the maintenance carried out at predetermined intervals
or according to prescribed criteria and intended to reduce
the probability of failure or the degradation of the
functioning and the effects limited.
 It has three types
 Running maintenance
 Scheduled maintenance
 Shut down maintenance

11. CONT..
1:Scheduled maintenance
 Time based maintenance consists of
periodically inspecting, servicing and cleaning
equipment and replacing parts to prevent
sudden failure and process problems.
2:RUNNING MAINTENANCE:
 It is a scheduled service visit carried out by an
agent, to ensure that an item of equipment is
operating correctly and to therefore avoid any
unscheduled breakdown and downtime.
3:shutdown maintenance
 That can only be performed when the
equipment, machine, or plant has been put out
of service.

12. B: Corrective maintenance
 In this type, actions such as repair, replacement, or
restore will be carried out after the occurrence of a
failure in order to eliminate the source of this failure or
reduce the frequency of its occurrence.
 It also include the different types of
actions like typical adjustment of redesign
equipment.
 The difference between corrective maintenance
and preventive maintenance is that for the
corrective maintenance, the failure should occur
before any corrective action is taken.
 It is of two types
1. Breakdown maintenance
2. Shutdown maintenance

13. CONT…
1. Breakdown maintenance
 It means that people waits until equipment
fails and repair it. Such a thing could be used
when the equipment failure does not
significantly affect the operation or production
or generate any significant loss other than
repair cost.
2:shutdown maintenance
 That can only be performed when the
equipment, machine, or plant has been put
out of service.

14. C: Predictive maintenance:
 As the names implies it involves the prediction
of the failure before it occurs, identifying the
root cause for those failures symptoms and
eliminating those causes before they result in
extensive damage of the equipment.
 Type of maintenance performed continuously or
at intervals according to the requirements to
diagnose and monitor a condition or system.

15. 2: Unplanned Maintenance:
 Maintenance action which is carried out
without any fore thoughts or prior planning
is called unplanned maintenance.
 Emergency maintenance is one of the
example of unplanned maintenance.
 In this type of maintenance the
maintenance action is executed with the
help of all available maintenance resources
in least possible time, without any major
time lag.
 Examples are gas leakage in chemical
plant, fire hazards, breakdown of boiler,
turbine etc.
