1. Consider the system of Example 34.1 on page 572.
Compute the average response time of the system if
the V_B = 6, S_CPU = 0.014 seconds, and S_B = 0.04seconds
2. Consider a set of M/M/1 3 servers, operating in tandem. If the
arrival rate to the system is 10 jobs per second, the
service rates
of the first and second server are 20 and 25 jobs per
second
respectively, what should the minimum service rate of the
third
server if the expected total number of jobs in the system
should be
no more than two?
3. What is the significance of Burke's Theorem and Jackson's Theorem?
