2.  Maintenance: The function of production
management, that is concerned with day -to-
day problem of keeping the physical plant in
good working condition.

3.  Maintenance management: Concerned with
planning, organising and directing the resources
in order to control the availability and
performance of the industrial plants to some
specified level.

4.  Maintenance means to maintain the
facilities in a system upto some desired
level of efficiency/some measure of
performance i.e to keep assets in a
satisfactory condition or to restore these
to that condition.
 Maintenance management is concerned
with planning and controlling Routine ,
Planned and Preventive maintenance
activities of an organization.

5.  Minimizing the loss of productive time.
 Minimizing the repair time and repair cost.
 Minimizing the loss due to production
stoppages.
 Prolonging the life of capital assets.
 Minimizing accidents.

6.  Minimizing the total maintenance cost and
improving the quality of product and
productivity.
 Minimize frequency and severity of
interruptions.
 Maximize production capacity – through high
utilization of facility by maximizing useful life
of equipment.

7.  Helps in cost control which leads to increased
profits.
 Facilitates delivery on time leading to customer
satisfaction.
 Makes the firm competitive.
 Helps in quality assurance.
 Helps in employee and customer safety.
 Facilitates Just-In-Time.

10.  It is an activity which prevents breakdowns,
cuts operating costs, and improve
output/quality of the product. It is a ‘Stitch in
Time’ procedure following the principle that
“Prevention is better than cure”. It involves
periodic cleaning, servicing, inspection, and
replacement of worn parts.

11. 1. Proper design and installation of
equipment.
2. Periodic inspection of plant and equipment
to prevent breakdowns before they occur.
3. Repetitive servicing, upkeep and overhaul
of equipment.
4. Adequate lubrication, cleaning and painting
of buildings and equipments.

12. • Lesser overtime payment to normal and
repair workers.
• Fewer large scale repairs and repetitive
repairs.
 Better spare part control leading to minimum
inventory level.
 Increased component life cycle.
• Energy and time saving.
• Reduced equipment or process failure.
• Cost savings and reduced capital
investment.

13.  Increases expenditure.
 Labour intensive.
 Reduces productivity, increases idle time
and cost of production.
 Includes performance of unneeded
maintenance.
 Potential for incidental damage to
components in conducting unneeded
maintenance.

14.  Also known as Breakdown maintenance, it
implies that repairs are made after the
equipment is failed and can not perform its
normal function anymore.

15. • Get equipment back into operation as
quickly as possible.
• Control cost of repairs.
• Control cost of the idle wages and
material wastage.
• Control the investment in replacement
spare parts and machines.
• Control accident cost and tool
breakage.

16.  Indifference towards minor faults.
 Too low or too high voltages.
 Indifference towards vibration or variant
sound in the system.
 Use of sub-standard or wrong fuel.
 Inefficient or neglected cooling system.

17.  No inspection cost.
 Low cost.
 Less staff.
 Production delay.

18.  It involves the identification of future problems
before they occur.
 Vital Attributes inspection.
 Use of sensitive instruments.
 Why Predictive?
 The cost of Preventive and Breakdown can be
reduced by using predictive maintenance.

19.  It is also known as scheduled maintenance or
productive maintenance.

21.  It includes activities such as periodic
inspection, cleaning, lubrication, and repair of
production equipments after their service life.
It is of two types:
b) Running Maintenance
c) Shutdown Maintenance

22.  Running maintenance
In this type of maintenance, maintenance work
is carried out while the equipment is in the
operating condition.
E.g.: Lubricating the bearing while the machine
is running.
