Write short notes on the following:
Categories of maintenance activities
Answer : Types of Maintenance activities:
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.
Mean Time Between Failures (MTBF)
Answer : MTBF (mean time between failures) is a measure of how reliable a
hardware product or component is. For most components, the measure is typically
in thousands or even tens of thousands of hours between failures. For example,
a hard disk drive may have a mean time between failures of 300,000 hours. A
desired MTBF can be used as a quantifiable objective when designing a new
product. The MTBF figure can be
Advantages of a Sound Replacement Program
Answer : Advantages of a Sound Replacement Program
Now that we have understood the reasons for
equipment replacement, let us now discuss some of the advantages of adopting a
sound replacement program. A sound equipment replacement program practiced will
accrue many benefits and afford advantages as detailed below:·
o
It reduces the cost and
TPM implementation
Answer : Following are the steps
involved by the implementation of TPM in an organization: Initial evaluation of
TPM level, Introductory Education and Propaganda (IEP) for TPM, formation of
TPM committee, development of master plan for TPM implementation, stage by
stage training to the employees and stakeholders on all eight pillars of TPM,
implementation preparation process, establishing the TPM policies and goals and
development of a road map for TPM implementation (Prabhuswamy, et al., 2013).

Explain briefly the functions of maintenance planning. What are the benefits of
maintenance planning?
Answer : Main functions
The Maintenance Service is entrusted
with the overall responsibility for keeping the irrigation and drainage systems
working in a satisfactory manner, within the limitations imposed by the initial
design.
Similarly
to the Operation Service, the main functions to be undertaken are:
- planning the maintenance activities;

What are the three stages in the lifecycle management of any machinery? Explain
in brief the Life cycle management system.
A
Listing of the three stages
Description of the stages with help of diagram(Life cycle management process),
examples
Answer : Three satages :
1.
Development
The development stage can be a
protracted stage and will involve activities such as design, planning, costing,
test marketing, etc. The costs are high, with no earned revenue (and thus it
does not register as a stage on the diagram at Figure A1-1). Promotion for
awareness may commence in advance of introduction of the product to the

Effective implementation of maintenance management in Quarta Technologies
Quarta Technologies is a leading manufacturing company in Bhopal. It
manufactures six million tubes a year. Each year, production shuts down for few
weeks allowing capital investment projects and deep maintenance to be
performed. These include process changes and a variety of maintenance
activities are executed.
The
Challenge
Ramping
up to full production capacity after the shut sown was a slow process with
attendant quality issues. The equipments used in this organisation were used
for several years before it was either discarded or replaced with a similar new
machine. From the time the equipment were brought, the production and
maintenance personnel accumulated considerable knowledge about the equipment,
the manner in which failures occur and the symptoms that it develops before a
particular failure or malfunctioning happen. The organisation recognised an
opportunity to reduce the quality costs of the annual shutdowns by planning and
troubleshooting techniques.
The
Solution
The
organisation, worked with the plant leadership to improve project and risk
management skills by introducing the common process. A progressive learning was
done with respect to equipment usage and systematically captures many types of
information and put to use. One method was to develop good trouble shooting
mechanisms. This mechanism was a structured approach to identify the root cause
of the problem that needs some correction when viewed from the maintenance. By
successively checking on a set of condition about the equipment, several
alternatives pertaining to the possible problematic areas will get eliminated
and progressively narrows down to a few. Once this stage is reached, it is
possible to conduct a detailed analysis to locate the problem and take
corrective measures.
This
helped the organisation to implement trouble shooting techniques which reduce
the shutdown period and a total of 110 distinct maintenance projects and
capital investments were managed. It also eliminated schedule conflicts that
would have caused delays. This technique helped them to achieve their goals,
ramping up faster to full production and improved team corporation.
What
was the challenge faced by Quarta Technologies? What steps were taken by them
to reduce it?
Answer : Challenge in implementation of maintenance management :
The
Changing World of Maintenance
Over the past twenty years,
maintenance has changed, perhaps more so than any other management discipline.
The changes are due to a huge increase in the number and variety of physical
assets (plant, equipment and buildings) which must be maintained throughout the
world, more complex designs, new maintenance techniques and changing views on
maintenance organization and responsibilities.

Write short notes on the following:
Routine maintenance
Answer : Defects that can be deferred
without serious discomfort, inconvenience or nuisance to the tenant or another
person or the long term deterioration of the building can wait the next
convenient maintenance visit. Likewise, all other repairs, of no threat to the
security or safety of the tenant can be with this 21 day period. Examples of
normal or routine maintenance include:
·
General joinery repairs
·
Repairs to internal doors, floors and windows
·
Repairs to walls (external & internal),
brickwork and slate/tiles
·
Repairs to gutters and downpipes
·

Explain briefly the twelve steps to be firmed up and practiced for successful
implementation of the Autonomous principles in a production unit.
Answer : Combining roles of operators
and maintenance specialists into a shared responsibility for maintaining
equipment. The transition to full workplace ownership by operators is divided
into seven steps, each followed by a management audit. Topics covered during
the workshop include overview of TPM, 6 Big Losses, Preventive Maintenance and
a seven step Autonomous Maintenance implementation.
The practical part of the workshop
focuses on the first three steps of AM: Initial Cleaning, Elimination of the
Sources of Contamination and Cleaning and Lubrication Standards. A pilot
machine is used as a training ground to learn machine
