4. What is the objective of Adaptive Control with Constraints? Draw the block diagram of a typical computerized Adaptive Control with Constraints system for drilling operation and explain in detail. [16]
5. (a) What is manual single station assembly and `manual assembly line’? Enumerate the dierences between them.
(b) A manual production flow line is arranged with six stations and a conveyor system is used to move parts along the line. The belt speed is 1.8 m/min and the spacing of raw workparts along the line is one for every 1.35 m. The total line length is 13.5 m, hence each station length equals 2.25 m.

(b) In a 10 station transfer line, the probability that a station break down will occur for a given work part is equal to 0.01. This probability is the same for all 10 stations. Determine the frequency of line stops per cycle on this flow line using the upper bound approach and also calculate the production rate. [8+8]
7. (a) Discuss the importance of vehicle management and safety in Automated Guided Vehicle System.
