Take a look at the following system:

Following are the basic statistics:

The probability of a process exiting after process #3 is 60%, and the probability that it will return to process 1 is 25%.

Several questions:

How long does it take the average job to be processed by the system?

2. The organization wishes to increase the job rate from 3/second to 30/second, yet they do not want the average time in any one queue to be more than 3 seconds. They are prepared to increase the number of servers for any processes where this is needed. How many processors are necessary for each process?

Under this model, what will be the average number of jobs in each of the queues?
