A NONPREEMPTIVE PRIORITY MAP/G/l QUEUE WITH TWO CLASSES OF CUSTOMERS

This p p e r considers a nunpreemptive priority queue with two classes of customers. Customers in each priority class arrive to the system according to a Markovian arrival process (MAP). Since the MAP is weakly dense in the class of stationary point processes, it is a fairly general arrival process. The service times of custcomers in ea,ch priority class are independent and identically distributed according to a general distribution function which may differ among two priority classes. Using both the generating function technique and t,he matrix analytic method, we derive various formulas for the queue length and waiting time distributions. We also discuss the algorithmic implement ation of the analytical results along with numerical examples.
