Instructions:
1. Attempt all questions.
2. Make suitable assumptions wherever necessary.
3. Figures to the right indicate full marks.
Q.1 (a) Define: Quality, Quality Control, and Total Quality Management. 03
(b)
Evaluate :
1. ?Quality is a relative term.?
2. ?Sampling is not a full proof exercise.?
04
(c) Explain Deming?s 14 point philosophy of TQM 07
Q.2 (a) Differentiate between Quality Control and Quality Assurance 03
(b) Explain DMAIC approach of 6sigma. 04
(c) Explain the procedure for getting ISO9001 certification, along with the three
essential audits.
07
OR
(c) Define sampling technique of inspection. What are different sampling
techniques? What are the benefits using sampling technique?
07
Q.3 (a) Explain the importance of Quality Circle 03
(b) Explain the Pareto principle with a suitable example. 04
(c) Explain the baye?s theorem with an appropriate example. 07
OR
Q.3 (a) Enumerate your views on Process capability and specified tolerances with
sketches.
03
(b) Explain any two Quality control tools. 04
(c) Explain cost of prevention and cost of appraisal in detail with the help of relevant
examples.
07
Q.4 (a) Explain Just in Time, Zero Inventory. 03
(b) Evaulate :
1. A number of Quality characteristics can be plotted using a p chart.
2. ?? ?
and R chart is less sensitive as compared to a p chart and can be used
effectively for the improvement of quality.
04
(c) Differentiate between variable & attribute type of data with appropriate
examples. Also describe the concept of variation in the context of manufacturing.
07
OR
Q.4 (a) Draw and brief about Operating Characteristics (OC) curve along with
Producer?s risk and Consumer?s risk.
03
(b) Draw a cause and effect diagram for reduced production rate in a manufacturing
firm.
04
(c) The functioning of a strategic experiment is monitored continuously by two
observation stations, A and B, functioning independently. It is necessary that at
least one of them function satisfactorily to monitor the progress of the
experiment. Each of these observation stations receives power supply from two
independent sources connected in parallel. A receives power from C and D, and
B receives from E and F. For each observation station, the power from any one
source is sufficient for operation. Draw the block diagram. Assume suitable
values of reliability of each element and calculate the reliability for the system.
