Multiserver retrial Queues with Two Types of nonpersistent Customers
We consider M/M/c/K (K ≥ c ≥ 1) retrial queues with two types of nonpersistent customers, which are motivated from modelling of service systems such as call centers. Arriving customers that see the system fully occupied either join the orbit or abandon receiving service forever. After an exponentially distributed time in the orbit, each customer either abandons the system forever or retries to ...
متن کاملA Tandem Queue with Two Markovian Inputs and Retrial Customers
A tandem retrial queue consisting of two stations is studied. The first station has a single server. An input flow at the first station is described by the Markovian Arrival Process ( MAP ). If a customer from this flow meets the busy server, it goes to the orbit of infinite size and tries its luck later on in exponentially distributed random time. The service time distribution at the first sta...
متن کاملA Single Server Retrial Queue in Bernoulli Schedule With Feedback on Non-Retrial Customers
In this paper, we consider an M/G/1 retrial queue with Bernoulli feedback and general retrial times where the external arrivals blocked either with probability q join the infinite waiting room called non-retrial queue or with probability p, (p+q = 1) leave the service area and enter the retrial group called orbit in FIFO discipline. Also we assume that only the customer at the head of the orbit...
متن کاملAn M2/g2/1 Retrial Queue with Priority Customers, 2 Optional Service and Linear Retrial Policy
Resumen Consideremos el sistema de colas con reintentos M2/G2/1 con dos tipos de clientes y política de reintentos lineal. Si un cliente llega al sistema y encuentra el servidor libre, entonces empieza su servicio inmediatamente. Si no, los clientes del primer tipo van a una cola y apenas se libera el servidor, el primer cliente empieza su servicio. El segundo tipo de clientes al encontrar el s...
متن کاملAsymptotic Analysis for Markovian Retrial Queues with Two Types of Nonpersistent Customers
We consider Markovian multiserver retrial queues where a blocked customer has two opportunities for abandonment: at the moment of blocking or at the departure epoch from the orbit. In this queueing system, the number of customers in the system (servers and buffer) and that in the orbit form a level-dependent quasi-birth-and-death (QBD) process whose stationary distribution is expressed in terms...
