17.7-10. Consider the E2/M/1 model with =4 and =5. This model can be formulated in terms of transitions that only involve exponential distributions by dividing each interarrival time into two consecutive phases, each having an exponential distribution with a mean of 1/(2)=0.125, and then defining the state of the system as (n,p), where n is the number of customers in the system ( n= 0,1,2,) and p indicates the phase of the next arrival (not yet in the system )(p=1,2). Construct the corresponding rate diagram (but do not solve further). 17.7-10. Consider the E2/M/1 model with =4 and =5.
