Queueing systems with many servers: Null controllability in heavy traffic [PDF]

open access: yes, 2006
A queueing model has $J\ge2$ heterogeneous service stations, each consisting of many independent servers with identical capabilities. Customers of $I\ge2$ classes can be served at these stations at different rates, that depend on both the class and the ...

Synthetic residential load models for smart city energy management simulations

open access: yesIET Smart Grid, 2020
The ability to control tens of thousands of residential electricity customers in a coordinated manner has the potential to enact system-wide electric load changes, such as reduce congestion and peak demand, among other benefits. To quantify the potential

A batch-service queueing model with a discrete batch Markovian arrival process [PDF]

open access: yes, 2010
Queueing systems with batch service have been investigated extensively during the past decades. However, nearly all the studied models share the common feature that an uncorrelated arrival process is considered, which is unrealistic in several real-life ...

Equilibrium balking strategies for a clearing queueing system in alternating environment [PDF]

open access: yesAnnals of Operations Research, 2011
We consider a Markovian clearing queueing system, where the customers are accumulated according to a Poisson arrival process and the server removes all present customers at the completion epochs of exponential service cycles.

Network Disruptions and Ripple Effects: Queueing Model, Simulation, and Data Analysis of Port Congestion

open access: yesJournal of Marine Science and Engineering, 2023
Disruptions often happen to ports and cause varying degrees of port congestion. This study employs a queueing model to investigate network disruption and the resultant ripple effects in the global transportation system.

Queueing-Based Simulation for Software Reliability Analysis

open access: yesIEEE Access, 2022
As modern software system is growing in size and complexity, the customer expectations for software quality have become higher. In the past, many software reliability growth models (SRGMs) were proposed and they are helped to evaluate the quality of ...

Bayesian inference for queueing networks and modeling of internet services [PDF]

open access: yes, 2011
Modern Internet services, such as those at Google, Yahoo!, and Amazon, handle billions of requests per day on clusters of thousands of computers. Because these services operate under strict performance requirements, a statistical understanding of their ...

Product forms for availability models [PDF]

open access: yes, 1992
This paper shows and illustrates that product form expressions for the steady state distribution, as known for queueing networks, can also be extended to a class of availability models.

A Multi-Tier Inspection Queueing System With Finite Capacity for Differentiated Border Control Measures

open access: yesIEEE Access, 2021
Both uniform quarantine and isolation measures, due to the COVID-19 pandemic, have brought forth unprecedented and severe socio-economic impacts. For the global post-COVID economic recovery, it is of great significance to explore scientific ways to ...
