On multiserver loss-delay queueing system with priority and no passine

الملخص EN

This investigation deals with a multiserver queueing model in which customers leave the system in the same chronological order in which they arrive.

The customers are assumed to arrive in Poisson fashion from two infinite priority and ordinary sources and their service times are identical and exponentially distributed.

The priority customers may wait but the ordinary customers are lost if all servers are busy.

We have derived analytical expressions for the expected waiting time of customers.

Some measures of system performance have been computed and graphs for expected waiting time versus traffic intensity have also been provided.
