Analysis of single server finite buffer queue under discouraged arrival and retention of reneging [PDF]
Yugoslav Journal of Operations Research, 2023 Queuing models where arrival rates go down consequent to increase in the number of customers are called systems with discouraged arrivals. Discouraged arrivals are distinct from balking in the sense that balking implies that arriving customers do not ...

Bounds For Markovian Queues With Possible Catastrophes
ECMS 2017 Proceedings edited by Zita Zoltay Paprika, Péter Horák, Kata Váradi, Péter Tamás Zwierczyk, Ágnes Vidovics-Dancs, János Péter Rádics, 2017 We consider a general Markovian queueing model with possible catastrophes and obtain new and sharp bounds on the rate of convergence. Some special classes of such models are studied in details, namely, (a) the queueing system with S servers, batch arrivals and possible catastrophes and (b) the queueing model with "attracted" customers and possible ...

MARKOVIAN QUEUES WITH CORRELATED ARRIVAL PROCESSES [PDF]
Asia-Pacific Journal of Operational Research, 2007 In an attempt to examine the effect of dependencies in the arrival process on the steady state queue length process in single server queueing models with exponential service time distribution, four different models for the arrival process, each with marginally distributed exponential inter-arrivals to the queueing system, are considered.

MATEC Web of Conferences, 2017 One of the most important characteristic of each queueing model is time to buffer overflow. In the paper the distribution of that time in a single-channel manufacturing system, modelled by a Markovian finite-buffer queue with machine breakdowns, is ...

Analysis of retrial queue with heterogeneous servers and Markovian arrival process
Informatika, 2020 Multi-server retrial queueing system with heterogeneous servers is analyzed. Requests arrive to the system according to the Markovian arrival process. Arriving primary requests and requests retrying from orbit occupy an available server with the highest ...

An innovative modelling proposal for the blood supply chain
Vox Sanguinis, EarlyView.Abstract Whole‐blood donation and apheresis are the only ways to obtain blood components for human use. Tools are being developed to improve the efficiency of blood donation systems by reducing waste, increasing donations and preventing shortages.

Age-based Markovian approximation of the G/M/1 queue
, 2021 International audienceWe extend the approach of Koole et al. (2012) [15] and Legros et al. (2018) [20] for the G/M/1 queue. The idea is to provide a Markovian approximation where a state represents the oldest customer's wait.

MathematicsThis paper analyzes a finite-capacity Markovian queueing system with two customer types, each assigned to a separate buffer, and a single alternating server whose service priority is dynamically controlled by a queue-length-based threshold policy.

Excursion theory for Markov processes indexed by Lévy trees
Proceedings of the London Mathematical Society, Volume 132, Issue 5, May 2026.Abstract We develop an excursion theory that describes the evolution of a Markov process indexed by a Lévy tree away from a regular and instantaneous point x$x$ of the state space. The theory builds upon a notion of local time at x$x$ that was recently introduced in the companion paper [Probab. Theory Related Fields. 189 (2024), 1–99].
