Answer ONE Question from each Unit
All Questions Carry Equal Marks
All parts of the question must be answered in one place only
UNIT I
1. Explain various modes of manufacturing in flexible manufacturing systems.
What are the different problems concerned in regular manufacturing process.
2. Explain what is low volume manufacturing of small batch manufacturing and their applications.

What are the aims, technical performance, improve order development and objects of flexible
manufacturing systems.
UNIT II
3. Explain backward scheduling approach in manufacturing, period of time and delivery with finite
capacity loading.
Distinguish between Real time vs.- discrete event control.
4. What is a dead lock in modeling. what are strategies used for dealing with dead locks.
Explain forward scheduling approaches with infinite capacity loading.
UNIT III
5. A 20 station transfer line is being proposed to machine a certain component currently produced
by conventional methods. The proposal received from the ma. chine tool builder states that the
line will operate at a production rate of 50 pc/hr at 100% efficiency. From similar transfer lines,
it is estimated that breakdowns of all types will occur with a frequency F 0.10 breakdown per
cycle and that the average downtime per line stop will be 8.0 min. The starting casting that is
machined on the line costs 3.00 per part. The line operates at a cost of 75.00/hr. The 20
cutting tools (one tool per station) last for 50 parts each, and the average cost per tool 2.00
per cutting edge Based on this data, compute the following:
i. Production rate
ii. Line efficiency
iii. Cost per unit piece produced on the line
Write a short note on limitations of simulation and factors of level of realism.
