ELEMENTARY MARKOV QUEUEING SYSTEMS WITH UNRELIABLE SERVER
Perner’s Contacts, 2009 This paper presents some examples of elementary Markov unreliable queueing systems and their mathematical models. Selected models are represented by a state transition diagram and by appropriate system of linear equations for steady state probabilities ...

Multi-Machine Repairable System with One Unreliable Server and Variable Repair Rate
Mathematics, 2021 This paper analyzed the multi-machine repairable system with one unreliable server and one repairman. The machines may break at any time. One server oversees servicing the machine breakdown. The server may fail at any time with different failure rates in

Retrial Queues with Unreliable Servers and Delayed Feedback [PDF]
Mathematics, 2021 In this paper, models of unreliable multi-server retrial queues with delayed feedback are examined. The Bernoulli retrial is allowed upon the arrival of both primary (from outside) and feedback customers (from orbit), as well as the Bernoulli feedback ...

Controlled Arrival Machine Repair Problem with Working Vacation and Reattempts [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2021 This paper addresses machine repair problem (MRP) with M identical operating machines and control arrival policy. The server is unreliable, and can break down during service which is further repaired soon so as to avoid interruption with the service ...

Optimal Profit Analysis of Machine Repair Problem with Repair in Phases and Organizational Delay [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2021 In this article, we study machine repair problems (MRP) consisting of the finite number of operating machines with the provisioning of the finite number of warm standby machines under the care of a single unreliable server.

Study of feedback retrial queueing system with working vacation, setup time, and perfect repair
Ratio Mathematica, 2021 This manuscript analyses a retrial queueing system with working vacation, interruption, feedback, and setup time with the perfect repair. In the proposed model, the server takes vacation whenever the system gets empty but it still serves the customers at

Results in Control and Optimization, 2023 The majority of the studies on queues with failing servers focused on catastrophic failures. Catastrophic failures are actually a particular kind of server failure that causes system clearing.
