The document discusses various types of maintenance including preventive, corrective, condition-based, predictive, reliability-centered, and value driven maintenance. It explains that preventive maintenance involves maintaining equipment before failures occur to prevent downtime and costs, while corrective maintenance repairs equipment after failures. Condition-based maintenance uses indicators to determine when equipment will fail and prioritizes maintenance. Predictive techniques help determine equipment condition to schedule maintenance. Reliability-centered maintenance aims to improve cost-effectiveness and uptime. The 5S methodology focuses on effective workplace organization through sorting, setting in order, shining, standardizing, and sustaining these practices.

2. • Maintenance involves fixing any sort of
mechanical or electrical device which has become
out of order or broken.
• It also includes performing routine actions
which keep device in working order or prevent
trouble from arising.

3.  Maintenance department implements
some maintenance operations to produce
products according to specific criteria.

4.  Before this department implement s
maintenance operations, they can be
categorized by whether the product remains
the property of the customer, service is
being offered, or whether the product is
bought by the reprocessing organization
and sold to any customer wishing to make
the purchase.

5. 1. Preventive Maintenance:
2. Corrective Maintenance:

6.  Preventive maintenance can be
described as maintenance of equipment or
systems before fault occurs.

7.  Corrective maintenance is probably the
most commonly used approach, but it is easy to
see its limitations. When equipment fails, it
often leads to downtime in production. In most
cases it is costly business. Also, if the equipment
needs to be replaced, the cost of replacing it
alone can be substantial. It is also important to
consider health, safety and environment issues
related to malfunctioning equipment.

8.  While preventive maintenance is generally
considered to be worthwhile, there are risks
such as equipment failure or human error
involved when performing preventive
maintenance, just as in any maintenance
operation.
 Preventive maintenance as scheduled
overhaul or scheduled replacement provides
two of the three proactive failure management
policies available to the maintenance engineer.

9.  Preventive maintenance is conducted to
keep equipment working or extend the life of
the equipment.
 Corrective maintenance, sometimes
called “repair” is conducted to get equipment
working again.

10.  Condition-Based Maintenance
 Predictive Maintenance
 Reliability-Centered Maintenance
 Value Driven Maintenance

11.  Shortly described, this maintenance is
performed after one or more indicators
show that equipment is going to fail or that
equipment performance is deteriorating.
 CBM was introduced to try to maintain
the correct equipment at the right time.
CBM is based on using real-time data to
prioritize and optimize maintenance
resources.

13.  Techniques help to determine the
condition of in-service equipment in order
to predict when maintenance should be
performed. This approach offers cost savings
over routine or time –based predictive
maintenance, because tasks are performed
only when warranted.

14.  Increased plant readiness due to greater reliability of
the equipment.
 Many industries report from two to ten percent
productivity increases due to predictive maintenance
practices.
 Reduced expenditures for spare parts and labor.
 Reduces the probability of a machine experiencing a
disastrous failure, and this results in an improvement
in worker safety

15.  It is generally used to achieve improvements
in fields such as the establishment of safe
minimum levels of maintenance, changes to
operating procedures strategies and the
establishment of capital maintenance regimes and
plans.
 Successful implementation of RCM will lead
to increase in cost effectiveness, machine uptime.
And a greater understanding of the level of risk
that the organization is presently managing.

16.  Based on five Japanese words that begin with ‘S’, the
5S Philosophy focuses on effective work place
organization and standardized work procedures.
5 S’s
1. Sort :(Seiri)
2. Set In Order:(Seiton)
3. Shine: (Seiso)
4. Standardize: (Seiketsu)
5. Sustain: (Shitsuke)

17.  The first S focuses on eliminating unnecessary
items from the workplace.
 An effective visual method to identify these unneeded
items is called red tagging.
 A red tag is placed on all items not required to
complete your job. These items are then moved to a
central holding area.
 This process is for evaluation of the red tag items.

18.  second S focuses on efficient and effective storage
methods and how to organize the work area.
 Strategies for effective Set In Order are painting floors,
outlining work areas and locations, shadow boards,
and modular shelving and cabinets for needed items
such as trash cans, brooms, mop and buckets

19.  Once you have eliminated the clutter and junk that has
been clogging your work areas and identified the
necessary items, the next step is to thoroughly clean
the work area.
 Workers will also begin to notice changes in
equipment and facility location such as air, oil, coolant
leaks, fatigue, breakage, and misalignment.
 These changes, if left unattended, could lead to
equipment failure and loss of production.

20.  Now the first three S’s are implemented.
 Use standard methods to keep Sort, Set In Order,
and Shine to a condition .
 Allow your employees to participate in the
development of such standards.

21.  This is the most difficult S to implement and achieve.
 Maintain through empowerment, commitment, and
discipline .
 Sustain focuses on defining a new status quo and
standard of work place organization.

22.  Simplifies work environment
 reduces waste
 Improves quality
 Improves safety
 Provide self esteem for everyone in the organization.
