Production and operations management involves maintaining machinery, equipment, and facilities. It includes planning maintenance activities to minimize downtime and costs. The goals of maintenance are to maximize efficiency, minimize accidents and costs, and improve productivity and quality. There are several types of maintenance: corrective maintenance occurs after breakdown; preventive maintenance aims to prevent failures; predictive maintenance uses instruments to anticipate failures; routine maintenance includes regular inspections; and planned maintenance follows a predetermined schedule. Overall, proper maintenance minimizes downtime and repair costs while extending equipment lifespan.

1. PRODUCTIONS &
OPERATIONS
MANAGEMENT

2.  It is a function that supports production function and
is entrusted with the task of keeping the machinery,
equipment and plant services in proper working
condition.
 It also involves planning, scheduling and execution of
maintenance activities and also controlling the costs of
maintenance

3.  Minimizes the loss of productive time due to breakdown of
equipments
 Minimizing the repair time and repair cost
 Reduction of losses due to production stoppage
 Efficient use of maintenance personnel and equipments
 Prolonging the life of capital assets by reducing the rate of wear
and tear
 Ensure that the equipments are in good working conditions

4.  To maximize efficiency and economy in production
 To minimize accidents caused during production
 To reduce the total maintenance cost such as labor,
repair cost, etc.
 To improve the quality of products and also to improve
productivity

5. 1. Break down maintenance (Corrective Maintenance)
2. Preventive maintenance
3. Predictive maintenance
4. Routine maintenance
5. Planned maintenance

6.  Corrective Maintenance occurs when there is a work
stoppage due to machine breakdown
To get the equipment back in operation as quickly as
possible in order to minimize its interruption in
production
 To control the cost of repair of operation of repair shops
and labor
 To control the investment in replacement of spare parts

7. 1. Limited personnel requirement
2. Reduced maintenance costs
3. Potentially increased margins
1. Unpredictability
2. May lead to stoppage of production
3. Indirect costs

8.  Preventive maintenance is undertaken before the need
arises and aims at minimizing the possibility of
unanticipated interruptions or breakdowns
 Installation of equipment
 Well qualified inspectors
 Inspections on a definite schedule
 Repetitive Servicing, upkeep and overhaul of
equipment
 Adequate lubrication, cleaning and painting.

9. 1. Over all it is cost effective
2. Increased equipment life
3. Reduces equipment or process failure
1. Labour Intensive
2. Time Consuming
3. It is expensive at initial stages

10.  Modern approach to preventive maintenance
 It uses sensitive instruments to predict anticipated
failure of machines and equipments
 It is measured periodically or on a continuous basis
 It is an extension to the service life
 It enables the management to plan for overhaul
 Eg: Vibration analyzers, audio gauges, pressure
temperature and resistance gauge

11. 1. Increased equipment life
2. Decrease in costs for parts and labor.
3. Better product quality.
4. Improved working conditions and environmental safety.
1. Increases investment in staff training.
2. Savings potential not readily seen by management.

12.  It includes activities such as periodic inspection, cleaning,
lubrication and repair of production equipments after their
service life. It can be classified into:-
i. Running Maintenance: In this method the maintenance
work is carried out while the equipment is in operating
condition. (Eg :- greasing or lubricating the bearings while
the machine is operating)
ii. Shut down maintenance: In this method the
maintenance work is carried out when the machine or
equipment is out of service. (Eg :- repairing boiler tubes of
a boiler)

13. 1. Cost effective
2. Better utilisation of equipments
3. Saves time in case of running maintenance
1. Sometimes the equipments can be outdated
2. Labor Intensive

14.  Maintenance activities that are carried out according
to a predetermined schedule is called as planned
maintenance
 It involves inspection of all plants, equipments,
machinery, etc.
 It aims at reducing machine stoppage due to sudden
breakdowns

15. 1. Over all very cost effective
2. Increased equipment life
3. Reduces equipment or process failure
1. Labour Intensive
2. Time Consuming
3. Increases Cost of Expense
