We consider a closed queueing network, consisting of two FCFS single server queues in series: a queue with general service times and a queue with exponential service times. A fixed number $$N$$ N of customers cycle through this network. We determine the joint ...
We consider a multiserver retrial GI / G / m queue with renewal input of primary customers, interarrival time with rate $\lambda=1/\mathsf{E}\tau$ , service time S , and exponential retrial times of customers blocked in the orbit. In the model, an arriving primary ...
