Note –Answer all questions. Kindly note that answers for 10 marks questions should be
approximately of 400 words. Each question is followed by evaluation scheme.
Q. 1. Write short notes on:
a) Need for maintenance management
Answer:Maintenance canbe definedasacombinationof all technical andassociatedadministrative
actionsintendedtoretainequipmentin,orrestore it to, a state in which it can perform its required
function. Industrial maintenance is interpreted in the context of industrial systems (such as
production facilities, buildings, equipment, and
b) Maintenance resources
Answer:Maintenance resourcesare Facilities, funding, personnel, spare parts, technical data, test
equipment,tools,etc.,availableorprovidedformaintenance operations. Aspects of good planning,
scheduling,and resource optimization of daily work are described in Chapter 24, Long Look-Ahead
Plan.
c) Decentralised maintenance
Answer:Decentralisation meansdiffusionof authority.The dispersalof authorityof decision-making
to the lower level management is termed as decentralisation. Decentralisation of authority is a
fundamental phase of delegation and the extent to which authority is not delegated is called
centralisation. According to Fayol "
d) Reliability Centred Maintenance
Answer:Reliability-centeredmaintenance (RCM) is a process to ensure that systems continue to do
what their users require in their present operating context. It is generally used to achieve

Q. 2. Optimizing Maintenance at XYZ Electricals
XYZ Electricals is one of the leading manufacturers of electrical utilities. The organisation is well
known for delivering quality products to consumers. It has adopted
A preventive maintenance (PM) approach for the maintenance of its machines and equipment.
However, in the last few months, the organisation has observed an increase in:
 Maintenance costs
 Facility downtime
 Frequent failures of components
After thorough analysis, it has been found that the main cause behind all the problems is the
excessive use of preventive maintenance. The organisation also realized that it must adopt a
maintenance process that maintains a balance between the requirements and resources of
maintenance.
Therefore, XYZ decided to implement maintenance optimization procedures in the plant. Various
optimizationtechniqueswere developedtoconverttraditional preventive maintenance intoa cost
- effective program. These techniques aimed at:
 Identifying assets that affect plant operations
 Identifying assets that may benefit most from preventive maintenance
 Selecting the most appropriate preventive tasks
 Combining appropriate traditional maintenance tasks with predictivemaintenance
tasks
 Implementing appropriate training methods to apply optimization techniques
After implementing maintenance optimisation techniques, the benefits that XYZ received after
optimising its maintenance are:
 Reduction in maintenance costs by removing unnecessary corrective maintenance
expenses
 Improvement in understanding of assets
 Application of cost – effective preventive maintenance techniques
 Better assessment of functioning of assets when they are in operation
What are the problems at XYZ Electricals? Which was adopted to overcome the problems? Assess
if the solution is effective in resolving the problem.
Answer:XYZElectricalsisone of the leadingmanufacturersof electrical utilities. The organisation is
well knownfordeliveringqualityproducts to consumers. It has adopted A preventive maintenance

3. Answer:Maintenance costs,Facilitydowntime andFrequentfailuresof components. After thorough
analysis, it has been found that the main cause behind all the problems is the excessive use of
preventive maintenance. The organisation also realized that it must adopt a maintenance process
that maintains a balance between the requirements and resources of maintenance.
Therefore, XYZ decided to implement
Q. 3. Write short notes on:
a) Production philosophy
Answer:The product philosophy was the dominant marketing philosophy prior to the Industrial
Revolution and continued to the 1920s. The product philosophy holds that the organization knows
itsproduct betterthananyone or anyorganization.The companyknowswhatwill work in designing
and producing the product and what will not work. For example, the company may decide to
emphasize the low cost or high quality of
b) Mean Time to Repair
Answer:MeanTime To Repair(MTTR) isa basicmeasure of the maintainabilityof repairable items.It
represents the average time required to repair a failed component or device. Expressed
mathematically,itisthe total corrective maintenancetime dividedbythe total numberof corrective
maintenance actionsduringagivenperiodof time. It generally does not include lead time for parts
not readily available or other Administrative or Logistic Downtime (ALDT).
c) Maintenance documentation
Answer: Maintenance is part of the Change Management process. Creating maintainable
documentationshouldbe amajorobjective forall Policies, Processes, and Procedures. The ease or
difficultyof maintenanceisdependentuponthe foundationestablished during the Planning phase.
With age, the quality of the Policies, Processes, and Procedures will lessen, if the Plan, Build, and
Change phases are not properly performed.
d) Online or permanent condition monitoring
Answer:Condition monitoring (or, colloquially, CM) is the process of monitoring a parameter of
conditioninmachinery(vibration,temperature etc.), in order to identify a significant change which
is indicative of a developing fault. It is a major component of predictive maintenance. The use of
conditional monitoring allows maintenance
Q. 4. Which are the common tasks performed in maintenance management?
Answer:Most Preventive Maintenance (PM) programs were set up many years ago. Each
departmentinaplant setup their ownprogramin isolationfromeachother.As an example, a plant
set up a PM program covering mechanical equipment, then another program was set up for
electrical equipmentandanotherto cover automation and control system. A lubricant vendor then
added lubrication routes and on top of this other PM activities such as Vibration Analysis and
Operator Inspections was added in addition to all
Q. 5. What are the benefits and issues related to predictive maintenance?

4. Answer:While many companies are perfectly satisfied with the performance of their outsourced
predictive maintenance (PdM) programs, some do not get the desired results for the time and
money expended. Others recognize that they have a pool of in-house talent that could do the job
givenenoughtime andtraining,orare facingbudgetcuts andpressuresthatforce limiting, reducing
or defunding PdM contracts.Vibration analysis is one of the most commonly used predictive
maintenance technologies in industry.
Q. 6. Write short notes on
a) Structure of maintenance budget
Answer:InFormerBudgeting,the budgetstructure representsall the fundscentersandcommitment
items in hierarchical form for each fund. The budget structure is year-dependent and is therefore
valid up until the time it has to be redefined due to new requirements. You define an individual
budgetstructure thatis year-independentforeachfundif youare using overall values for this fund.
By using posting objects you specify which BS elements can be posted. The standard setting for
Funds Management supports postings of actual
b) Role of maintenance auditor
Answer: Audit is the process of checking accounting entries as per norms and guideline by the
accounting professionals. The Companies Act,1956 provides for compulsory appointment of an
independentpersonasthe 'auditor'of the companywhose responsibilityistoexamine the affairs of
the company and to report it to the
c) Codification of spare parts
Answer:Codification /cataloguingisbasicallyanidentificationsystemforeachitemof the inventory.
Normally, it is the custodian who does the codification for the items he keeps in his inventory.
However, in firms of substantial sizes where good number of items are received on regular basis ,
codification is usually done by a team
