Retrial queues are frequently observed in a real world system likewise call center or internet service industries. In this paper, a retrial queue system in which the number of retrials of each customer is limited by a finite number, say m is considered. That is, if a customer fails to enter the service facility at mth retrial, then the customer leaves the(More)
We present an algorithmic solution for the stationary distribution of M/M/c/K retrial queue which consists of an orbit with infinite capacity and a service facility that has c exponential servers and waiting space of size K− c. The behavior of queue length process in the retrial queue is described by level dependent quasi-birth-and-death (LDQBD) process due(More)
