Dimensioning the Optimal Number of Parallel Service Desks in the Passenger Handling Process at Airports Considered as a Queueing System—Case Study

open access: yesAerospace, 2023
Queueing theory is currently a widely used method for optimizing activities not only in air transport but also in other sectors, in both production and the use of personnel.

Queueing Systems with Random Volume Customers and a Sectorized Unlimited Memory Buffer

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2021
In the present paper, we concentrate on basic concepts connected with the theory of queueing systems with random volume customers and a sectorized unlimited memory buffer.

Application of queueing models with abandonment for Call Center congestion analysis [PDF]

open access: yesGestão & Produção, 2020
This paper studies and applies queueing systems to Call Centers regarding the possibility of customer abandonment from the system before being served due to their impatience in waiting for a service.

Optimization Method of Dynamic Beam Position for LEO Beam-Hopping Satellite Communication Systems

open access: yesIEEE Access, 2021
The beam-hopping (BH) technology applied to low earth orbit (LEO) satellite communication networks is a superior choice, but the long transmission delay partly caused by data packets waiting in the queue of satellite transponders will seriously affect ...

The number of overtakes in an M/M/2 queue

open access: yesOperations Research Perspectives, 2018
The phenomenon of overtaking in queueing systems and queueing networks has been addressed by several authors with various motivations in the last decades. Nevertheless, up to now, for the relatively simple M/M/2/FCFS queue, the distribution of the number

Analysis of Closed Queueing Networks with Batch Service [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2020
We consider a closed queuing network with batch service and movements of customers in continuous time. Each node in the queueing network is an infinite capacity single server queueing system under a RANDOM discipline.

A survey of parameter and state estimation in queues

open access: yes, 2021
We present a broad literature survey of parameter and state estimation for queueing systems. Our approach is based on various inference activities, queueing models, observations schemes, and statistical methods.

When queueing is better than push and shove [PDF]

open access: yes, 2006
We address the scheduling problem of reordering an existing queue into its efficient order through trade. To that end, we consider individually rational and balanced budget direct and indirect mechanisms.

Isomorphs of a class of Queueing systems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1979
Restricted isomorphism between two queueing systems implies that they have equivalent distribution function for at least one (but not all) output elements (e.g. waiting time, queue size, idle time, etc.).

Continuous-Service M/M/1 Queuing Systems

open access: yesApplied System Innovation, 2019
In this paper, we look into a novel notion of the standard M/M/1 queueing system. In our study, we assume that there is a single server and that there are two types of customers: real and imaginary customers. Real customers are regular customers arriving
