Note: There are many possible ways of solving these problems. What is given here is just one (presumably
more common) way of solving them.
1. (3 marks) Number of clients to support (M) = 200
Average think-time of each client (1/) = 4 seconds
=
1
4
The system should not be saturated for 200 clients. Thus (Ref: Eq# 8.71, Trivedi 2/e):
M
= 1 +
µ

200 = 1 + 4µ
µ =
199
