Part C X 10 30)
Answer all questions.
16. In a railway marshalling yard, goods trains arrive
at a rate of 30 trains per day. Assuming that the
inter arrival time follows an exponential
distribution and the service time distribution is also
exponential with an average of 36 minutes.
Calculate
expected queue size (line length)
probability that the queue size exceeds 10, if
the input of trains increases to an average
of 33 per day, what will be the change in
and
Or
What is an infeasible solution, and how does it
occur? How is this condition recognized in the
graphical method?
17. A computer centre has three expert programmers.
The centre wants three application programmes to
be developed the head of the computer centre, after
carefully studying the programmes to be developed,
estimates the computer time in minutes required by
the experts for the application programmes as
follows
Programmers
A B C
1 120 100 80
Programmes 2 80 90 110
3 110 140 120
Assign the programmers to the programmes in such
a way that the total computer time is minimum.
Or
Explain how an assignment problem can be solved
by using the transportation approach.
