Q1. What are the stages in the lifecycle management of any machinery? (List the stages in
the lifecycle management of any machinery, Explain what is done in each stage , you may
use examples if needed.) 1, 9
Answer:
Asset Life Cycle Management
Every asset has its own life cycle. The managerial efficiency and effectiveness lies with the
fact as to how well they utilise the asset within its life cycle. The maintenance methods are
used to keep the machines working to its optimum efficiency levels within that life cycle and
obtain maximum benefits. With state of art machineries being deployed for production, the
demand to produce high quality products to high volumes, demands the best maintenance
management system over the life cycle of the machineries. .
Q2. Write short notes on:
 Fault tree analysis for improving maintenance effectiveness
 Routine maintenance
 Problems in maintenance scheduling
 Wrench Time
Answer: Fault Tree Analysis
.
For improving maintenanceeffectiveness oneof thetools used is the fault tree analysis.
In electrical and control systems, failures are linked to certain physical portions of the
equipment. For instance, non operation of a set of wiring combinations in an electrical
system may result in certain types of failures. To know the root cause of the problem, it
may be necessary to isolate the circuit so that the failed segment could be identified
immediately.

2. A fault tree is therefore a network diagram of the circuitry that facilitates tracing the
component failure to specific portion of the network, thus helping maintenance
personnel to directly attend the problem.
Q3. Why detail analysis and use of different methods are essential requirements for
taking suitable decisions on the equipment replacements? Explain briefly these
methodologies used.
(Reasons for detail analysis and use of different Methods:Decision Tree method-2 marks,
Minimum Annual Cost method-2 marks, Barnes Formula method-2 marks, MAPI Method-2
marks) 10 marks
Answer-3
The method of replacement and its analysis is similar to those adopted while procuring the
equipments under original investment plans of the project, except for the following
differences:
The original investment analysis was made from purely investment and returns basis,
whereas in case of replacement the estimation will also consider the residual serviceable life
the existing equipment.
Q4. Explain briefly the ABC classification and reasons behind recommending ABC and
VED classifications for managing inventory of spare parts for maintenance?
(Explanation of ABC classification including class-6 marks, items and their features
reasons behind
recommending ABC and VED classifications for managing inventory-4 marks) 10 marks
Answer-4
Classification of Inventories
Let us discuss about the inventory control methodologies that are practiced and see which
common method out of these could be adopted in inventory management of spare parts.
Inventory of production items, components, and aggregates are classified into groups based
on their relative importance with respect to availability, the economy or the lead time for
procurement. Inventory items are classified and controlled based on some criterions.
Q5. Explain briefly the universal principles used for improving productivity of the
maintenance management
(Scientific principle-1 mark, Measurement and control-2 mark , Activity and
responsibility-1 mark, Customer and service relationship-2 marks, Crew size-2 marks,
Timelines-2 marks) 10 marks
Answer-5

3. Total Productive Maintenance (TPM) is a business process improvement method, developed
from the perspective of maintenance management. TPM concentrates on productivity
improvement, primarily by way of maximizing the availability of equipment.
Scientific principle
Best productivity results can be achieved when each worker has a definite job to do in a
definite way within a definite time. Here the Frederick Taylor‟s principle of scientific
management can be applied to all tasks and hence maintenance can also adopt the
principles laid out by Taylor.
Q6. What is meant by ‘Overall Equipment Effectiveness (OEE)’? What are its constituents
and objectives served? List the OEE Losses?
(Concept-2 marks, Components/constituents-3 marks, objectives served by OEE,
calculation of OEE-3 marks, Listing of OEE losses-2 marks) 10 marks
Answer-6
Overall Equipment Effectiveness (OEE)
The central concept of TPM philosophy is to maximize the “Overall Equipment
Effectiveness (OEE). The success of TPM program is related to recognizing OEE as an
important measure for maintenance management OEE is defined as the product of the
availability of the equipment and
