Multi-server queueing system with reserve servers

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2019
In this paper, we investigate a multi-server queueing system with an unlimited buffer, which can be used in the design of energy consumption schemes and as a mathematical model of unreliable real stochastic systems.

Optimal Pricing Analysis of Computer Networks Based on a Queueing System With Retrial Mechanism

open access: yesIEEE Access, 2020
We consider a single-server retrial queue with a Poisson arrival process and exponential service times, where the server is unreliable. Assume there is no waiting space in front of the server and the customer who finds the server unavailable joins an ...

When do children learn from unreliable speakers? [PDF]

open access: yes, 2009
Children do not necessarily disbelieve a speaker with a history of inaccuracy; they take into account reasons for errors. Three- to 5 year-olds (N = 97) aimed to identify a hidden target in collaboration with a puppet.

Stochastic analysis of a single server unreliable queue with balking and general retrial time

open access: yesDiscrete and Continuous Models and Applied Computational Science, 2020
In this investigation, we consider an M/G/1 queue with general retrial times allowing balking and server subject to breakdowns and repairs. In addition, the customer whose service is interrupted can stay at the server waiting for repair or leave and ...

Asymptotic analysis of MMPP/M/1 retrial queueing system with unreliable server [PDF]

open access: yes, 2022
In this paper, we study a single-server retrial queueing system with arrival Markov Modulated Poisson Process and an exponential law of the service time on an unreliable server.

Deep edge intelligence-based solution for heart failure prediction in ambient assisted living

open access: yesDiscover Internet of Things, 2023
Heart failure and heart disease prediction in real-time is a highly significant necessity for the patients living under the observation of Internet of Things-based Ambient Assisted Living systems because cardiovascular diseases are the most common fatal ...

Performance analysis of bulk arrival queue with balking, optional service, delayed repair and multi-phase repair

open access: yesAin Shams Engineering Journal, 2018
In this investigation, single repairable server queueing system with bulk input and state dependent rates is analyzed by considering the general distributions for the repair, delay to repair and service processes.

Asymptotic diffusion analysis of RQ system M/M/1 with unreliable server

open access: yesDiscrete and Continuous Models and Applied Computational Science
The paper considers a single-line retrial queueing system with an unreliable server. Queuing systems are called unreliable if their servers may fail from time to time and require restoration (repair), only after which they can resume servicing customers.

MX/G/1 unreliable retrial queue with option of additional service and Bernoulli vacation

open access: yesAin Shams Engineering Journal, 2016
In this paper, retrial queue with unreliable server and bulk arrivals is investigated. The server is capable of providing m-optional services and any one of these available services, may be rendered to the customer after the first essential service if ...

A study on an M/G/1 retrial G-queue with unreliable server under variant working vacations policy and vacation interruption [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2018
We consider a single server retrial queueing system with variant working vacations and vacation interruption where the regular busy server is subjected to breakdown due to the arrival of negative customers.
