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. What are the basic components of flexible manufacturing systems. Explain with suitable example.

What are the different types of flexible manufacturing systems. Explain with suitable example.

2. Diagrammatically explain any one type of flexible manufacturing systems layout.
What are the different factors effecting flexible manufacturing systems layouts.
UNIT II
3. What are the advantages and disadvantages of centralized control.
Explain backward scheduling approach with infinite capacity loading.
4. Explain forward scheduling approach with finite capacity loading.
Explain the terms conflicts and synchronization in terms of modelling issues.
UNIT III
5. What are the interwoven steps involved in simulation modeling.
A 20-station transfer line is divided into two stages of 10 stations each. The ideal cycle time of
each stage is To "" Lz mln. All of the stations in the line have the same probability of stopping,
p 0.005. We assume that the downtime is constant when a breakdown occurs, Td 8.0 min.
Using the upper-bound approach, compute the line efficiency for the following buffer capacities:
i. b 0
ii. b 10
iii. b 100
6. What are the issues related with deterministic and stochastic modelling.
Differentiate between transfer lines with buffer storage and without buffer storage.
