SYSTEM APPROACH
TO MAINTENANCE
110
COURSE LEARNING OUTCOME (CLO)
1. Analyze the concepts of maintenance organization
and strategies to solve related problems.
2. Apply the principles of maintenance strategies and
elaborate on the significance of a system approach
to maintenance.
3. Organize maintenance management plan and
schedule that integrates the whole management
processes and procedures by group in actual
workplace.
111
MAINTENANCE CONTROL SYSTEM
Maintenance management control system is meant to
increase productivity, efficiency and improve
profitability with reduced losses/wastages.
The objective of maintenance is to achieve the correct level
of operational reliability and the best possible personal safety
at minimum cost.
It can be facilitated through:-
(i) design changes, improved lubricants, improved
suspension system, calibration, alignment, etc.
(ii) all of which that can reduce the need for
maintenance.
112
MAINTENANCE CONTROL SYSTEM
The following items must have clear methods and procedures
of handling in any effective maintenance control system :
1. Maintenance Demand ( What work to be done and when)
2. Maintenance resources ( who will do the work and what material
and tools needed)
3. Procedures means for coordinating, scheduling and executing
the work.
4. Performance and quality standards (how long it takes to do a
job and acceptable specification)
5. Feedback monitoring and control
113
MAINTENANCE CONTROL SYSTEM
6 phases of GOOD maintenance management
114
MAINTENANCE CONTROL SYSTEM
Provides an enterprise database that enables to capture and
analysis data about current and historical maintenance work
Help keep track
❑ Cost of maintenance
❑ Work order
❑ Labor time
❑ Key performance indicators (KPIs)
❑ Bench marks throughout the maintenance operation
Few software available for such approach
❑ CMMS (computerized maintenance management systems)
115
MAINTENANCE CONTROL SYSTEM
116
SYSTEM APPROACH TO MAINTENANCE :
MAINTENANCE WORK ORDER
The work order system :
❑ A format used for the detailed information →The vehicle for
planning and controlling maintenance work.
❑ It also provides the needed information for monitoring and
reporting maintenance work → All of maintenance jobs are
initiated through written work order (in form a card or computer
printout).
❑ A clear goal and effective procedures are essential for the
implementation of the work order system and control of
maintenance activities.
❑ Monitored till completion and finally documented into history
system.
117
SYSTEM APPROACH TO MAINTENANCE :
MAINTENANCE WORK ORDER
❑ Work orders can include maintenance, repair and new work.
❑ A work order system should cover all the maintenance jobs
requested and accomplished, whether repetitive or one-time
jobs.
❑ Although the type and size of the work order can vary from one
maintenance organization to another, a work order should at
least contain information such as:
→ requested and planned completion dates
→ work description and its reasons
→ planned start date
→ labor and material costs
→ item or items to be affected
→ work category (preventive maintenance, repair, installations)
→ appropriate approval signatures.
118
SYSTEM APPROACH TO MAINTENANCE :
MAINTENANCE WORK ORDER
Purpose Of Maintenance Work Order System :
1. Requesting in writing the work to be performed.
2. Assigning the best method and safety to perform work in an
estimated amount of time.
3. Reducing cost through man-hours and material control.
4. Performing predictive and preventive maintenance.
5. Improving planning & scheduling of maintenance work.
6. A source of data collection for reporting time standard
development and control.

SYSTEM APPROACH TO MAINTENANCE :
MAINTENANCE WORK ORDER
122
SYSTEM APPROACH TO MAINTENANCE :
MAINTENANCE WORK PERMITS
◼ The components of work order
◼ The maintenance department issues to different executing
agencies (mostly outside agencies)
◼ Work permits are any form of authorization/notification that all
precautions/limitations have been addressed and the work
area/condition/safety concern has been secured from a safety
standpoint.
◼ Work permits take into account the scope of the Work
Package/Task activity and the affected area/component and
address specific areas of safety (i.e., fire protection, air quality,
scaffold erection, system/component isolation, etc.).
◼ Work permits are first and foremost for the protection of
personnel. In addition, work permits ensure the protection of
company assets.
123
SYSTEM APPROACH TO MAINTENANCE :
JOB CARDS & JOB CARD PROCEDURES
Job card
→ concentrates for necessary details performing each individual
job
→ in the form of card, sheet or printed out
→ prepared manually or through computers
→ is a schedule of job and filled up in every job
Job card procedure
→ The filled up job card are initiated by concerned maintenance
personnel and sent to computer section or planning/
documentation section for processing
→ The complied information from job cards will give feedback to
maintenance engineer/ plant engineer
124
SYSTEM APPROACH TO MAINTENANCE :
JOB CARDS & JOB CARD PROCEDURES
125
SYSTEM APPROACH TO MAINTENANCE :
JOB EXECUTION, MONITORING, FEEDBACK & CONTROL
Job Execution
After jobs are planned and schedule, the schedule/ charts/ job
cards are distributed to different agencies/ men and the execution
of job starts continued as per revised schedule if any from time to
time, till the job are completed.
126
SYSTEM APPROACH TO MAINTENANCE :
JOB EXECUTION, MONITORING, FEEDBACK & CONTROL
Monitoring
Constant follow up and monitoring is very essential during the
whole period of execution of repair and maintenance
Role:
◼ Gather information about any deviation, delay in time schedule
◼ Communicate to follow up agencies
◼ Provide information about constraint
◼ Provide lead to implement technical advancement
Methods:
◼ Daily (once or twice) brief meeting
◼ Repair coordinator to check and update/mark PERT/CPM/bar
chart daily twice and intimate the deviations and corrective
actions to all agencies
127
SYSTEM APPROACH TO MAINTENANCE :
JOB EXECUTION, MONITORING, FEEDBACK & CONTROL
Feedback
Feedback information and corrective action is concerned with the
collection of data about the status of the work execution, system
availability, work backlog, quality of work performed. Then this
information is analyzed and an appropriate course of action is
formulated.
- Inter-departmental or intra-departmental (within different
sections/areas of department)
- Communication on related topics/matters.
- Immediate and frequent feedback about the status of repair job,
on going work, suspended/stopped work report with reasons,
work completion report, manpower engagement report, cost
report.
- Very essentials for corrections.
128
SYSTEM APPROACH TO MAINTENANCE :
JOB EXECUTION, MONITORING, FEEDBACK & CONTROL
Control
Based on monitoring and feedback system, the total control of
repair and maintenance job can be done effectively to optimize time
and cost.
This could be done by :
◼ Continuous or periodical checking
◼ Inspection of the condition/status
◼ Comparing the condition/status
◼ Budgetary control

SYSTEM APPROACH TO MAINTENANCE :
CODIFICATION AND CATALOGUING
Definition of Codification.
Codification implies evolution and employment of a code or a
system that uses a uniform pattern of numbering the items and
denoting each item by a well defined scientific nomenclature which
will uniquely identify a store when so referred to.
Codification Process.
Codification process involves:-
(a) Item Identification. Identifying items on the basis of their
characteristics, usage and manufacture and assigning an approved
item name and description.
(b) Classification. Classifying items into appropriate
classes in accordance with the system.
131
SYSTEM APPROACH TO MAINTENANCE :
CODIFICATION AND CATALOGUING
(c) Allotment of a Number. Assigning to items a unique item
identification number. Cataloguing is the resultant activity of the
codification and involves arranging the items in a certain sequence
to form a catalogue. The catalogue is essentially a list of items that
are in use.
(d) Recording of Identification Data. Keeping a record of
the identification data of all items codified and allotted for compiling
a catalogue and for checking whether a similar item has not already
been codified.
132
SYSTEM APPROACH TO MAINTENANCE :
CODIFICATION AND CATALOGUING
Definition of Cataloguing.
◼ Cataloguing is the procedure whereby a designer manufacturer,
inspector, stockist or supplier prepares an inventory of his
wares.
◼ The system and the organization for doing so depends upon the
size and the magnitude of the task (numbers of item involved);
the larger the number of items the more elaborate is the
machinery needed for the preparation and maintenance of
catalogues and allied publications.
133
SYSTEM APPROACH TO MAINTENANCE :
CODIFICATION AND CATALOGUING
◼ Essentially a catalogue is a list of items arranged in alphabetic
sequence of their nomenclature (i.e., item name and
description). To prevent confusion, there must be no ambiguity,
vagueness or variation in the exact nomenclature.
◼ It must be arranged in groups and classes based on
technical, functional, user or technical-cum-user affinity basis.
As nomenclature of the items, consisting of an item name and
description are usually rather long, each item must have a short
reference or code from which an identifiable description can be
decoded. This is provided by allotting a catalogue number to the
item as each catalogue number is associated with an
appropriate description.
134
SYSTEM APPROACH TO MAINTENANCE :
CODIFICATION AND CATALOGUING
◼ A catalogue, therefore, consists of a number of logical groups
and classes. This is the standard system of cataloguing of
universal usage.
◼ Additional information like specification, titles and reference,
drawing authority and reference, supplier’s/manufacturer’s
identity and reference may be shown in a Catalogue.
135
SYSTEM APPROACH TO MAINTENANCE :
CODIFICATION AND CATALOGUING
Benefits of Codification.
A proper and uniform codification will facilitate inventory control and
management in the following manner:-
(a) A systematic discipline helps the users to identify the required
item correctly, stock controllers to issue, purchase authority to buy the
correct item and organizations to select the correct item from the
existing inventory.
(b) An identification number achieves economy in transactions and
makes automatic data processing possible.
(c) Codification reduces variety, prevents overstocking and reduces
purchase cost by revealing duplicate and interchangeable items.
(d) Codification helps in rationalization, standardization and
propagates the use of standard items.
(e) Reveals interchangeability of items within and between the
Services.
136
SYSTEM APPROACH TO MAINTENANCE :
CODIFICATION AND CATALOGUING
Codification of equipment and components
Following to cares are to be taken while using such codification of
equipment and components.
◼ All concerned persons should be made aware of codes and
codification system.
◼ For standard bought out components/items confirming to
national, international or reputed manufacturers own codes and
catalogues, a fresh number confirming to user plant as existing
centralized system may be given but some suitable
character/digits should be introduced and a cross linking as to
be documented.
137
SYSTEM APPROACH TO MAINTENANCE :
CODIFICATION AND CATALOGUING
Such codification is not only used for maintenance but also by
material management department, by finance department, by
project department and also by other departments. For
maintenance functions, following categories of codification are
extensively used:-
◼ Drawing codification
◼ Equipment codification
◼ Parts/spares codification
◼ Maintenance defects and maintenance jobs codification, etc.
138
SYSTEM APPROACH TO MAINTENANCE :
“HISTORY CARD” OR “HISTORY SHEET”
• Preparation of “ History Card” or “History Sheet” including for
each system, equipment and major assemblies
• These give a few essential information about acquisition of the
asset and material which are permanent records
• Few to be update regularly are manual records like cards,
sheets or registers or in computer
139
SYSTEM APPROACH TO MAINTENANCE :
“HISTORY CARD” OR “HISTORY SHEET”
It is necessary to record the following:
1. Equipment specifications and location.
2. Inspections, repairs, servicing and adjustments carried out, and
break downs and failures and their causes and the corrective
action undertaken.
3. Work done on the equipment, component repaired or replaced,
condition of wear and tear, erosion, corrosion, etc.
4. Measurements or readings taken, clearance, results of tests and
inspections.
5. Failure time and the time lost to carry out repairs.
