Question No: 57 ( Marks: 3 )
Explain the basic purpose of acceptance sampling?
Acceptance sampling is an important form of inspection applied to lots or batches of
items before or after a process, to judge conformance with predetermined standards.
A point to remember is that the main purpose of acceptance sampling is to decide
whether or not the lot is likely to be acceptable, not to estimate the quality of the lot.
Question No: 58 ( Marks: 3 )
Briefly discuss Part-Period Model with the help of an example?
Part-Period Model represents an attempt to balance set up and holding costs.
The part period term refers to holding part or parts over a number of periods, e.g. if a
business holds 20 parts for 3 periods this would be a 20 X 3= 60 parts period.
Question No: 59 ( Marks: 3 )
Compute slack time for each of the following activities in the following table:
Activity Schedule
LS ES Slack
1-2 0 0 0
1-3 6 0 6
2-4 10 8 2
Slack Time = LS-ES
Question No: 60 ( Marks: 3)
For what purpose the transportation method is used?
Transportation Method is a quantitative approach that can help solve multiple facility
location problems.
It is used to determine the allocation pattern that can be used to minimize the cost of
shipping products from two or more plants or sources of supply to two or more
warehouses or destinations.
C Based on Linear Programming.
C It does not solve all the problems of the multiple facility location.
C It only finds the best shipping pattern between plants and warehouses for a particular
set of plant locations with a given capacity.
C The Operations manager or logistics analyst must try a variety of location-capacity
combinations and use this to find the optimal distribution for each alternative.
C Distribution costs (variable shipping and possible variable production costs) are
important inputs in evaluating a particular location allocation combination.
C Investments costs and other fixed costs are also considered.
C Qualitative factors (like land and construction cost against annual profits) are also
included in the analysis for each location capacity combination.
Question No: 61 (Marks: 5)
You are employed as an operations manager in ABC Company. At some stage you
make an analysis of the changes in product design. What analysis you carry out to
feel this change? Also elaborate its different procedures
Methods analysis deals with analyzing how a job gets done, begins with overall analysis
and then moves to specific details like changes in tools and equipment, Changes in
product design or new products, Changes in materials or procedures and other factors
(e.g. accidents, quality problems)
Methods Analysis Procedure is simple and effective and does the following
C identifies the operation to be studied
C Gets employee input
C Studies and documents the current method
C analyzes the job
C proposes new methods
C installs new methods
C Follow-ups to ensure improvements have been achieved

Question No: 63 ( Marks: 5 )
EDI is beneficial for organization. Elaborate some of the rewards of EDI to an
organization.
Electronic data interchange (EDI) is the structured transmission of data between
organizations by electronic means. It is used to transfer electronic documents or business
data from one computer system to another computer system, i.e. from one trading partner
to another trading partner without human intervention.
Electronic Data Interchange gives an organization the following benefits and advantages.
1. Increased productivity
2. Reduction of paperwork
3. Lead time and inventory reduction
4. Facilitation of just-in-time systems
5. Electronic transfer of funds
6. Improved control of operations
7. Reduction in clerical labor
8. Increased accuracy
Question No: 64 ( Marks:5)
What are the various assumptions an operations manager needs to consider for
implementing priority rules? Deterministic
Assumptions to Priority Rules
1. The set of jobs is known, no new jobs arrive after processing begins and no jobs are
cancelled.
2. Setup time is deterministic
3. Processing times are deterministic rather than variables.
4. There will be no interruptions in processing such as machine breakdowns, accidents or
worker illnesses.
