An M/g/1 Retrial Queue with Second Multi-optional Service, Feedback and Unreliable Server
An M/G/1 retrial queue with two-phase service and feedback is studied in this paper, where the server is subject to starting failures and breakdowns during service. Primary customers get in the system according to a Poisson process, and they will receive service immediately if the server is available upon arrival. Otherwise, they will enter a retrial orbit and are queued in the orbit in accorda...
متن کاملUnreliable Server Mx/G/1 Queue with Loss-delay, Balking and Second Optional Service
This investigation deals with MX/G/1 queueing model with setup, bulk- arrival, loss-delay and balking. The provision of second optional service apart from essential service by an unreliable server is taken into consideration. We assume that the delay customers join the queue when server is busy whereas loss customers depart from the system. After receiving the essential service, the customers m...
متن کاملWorking Vacation Queue with Second Optional Service and Unreliable Server
An M/M/1 queueing system with second optional service and unreliable server is studied. We consider that the server works at different rate rather than being idle during the vacation period. The customers arrive to the system according to Poisson process with state dependent rates depending upon the server’s status. All customers demand the first essential service whereas only some of them dema...
متن کاملUnreliable MX / G / 1 retrial queue with multi - optional services and impatient customers
Abstract: The present investigation deals with M/G/1 retrial queue with unreliable server and general retrial times. The server is subject to breakdowns and takes some setup time before starting the repair. The server renders first essential phase of service (FES) to all the arriving customers whereas second optional phase services (SOS) are provided after FES to only those customers who opt fo...
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...
