Transform Methods for Heavy-Traffic Analysis [PDF]

open access: yesStochastic Systems, 2020
The drift method was recently developed to study queuing systems in steady state. It was used successfully to obtain bounds on the moments of the scaled queue lengths that are asymptotically tight in heavy traffic and in a wide variety of systems, including generalized switches, input-queued switches, bandwidth-sharing networks, and so on.

Online Bandwidth packing with symmetric distribution [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2007
We consider the following stochastic bin packing process: the items arrive continuously over time to a server and are packed into bins of unit size according to an online algorithm. The unpacked items form a queue.

Diffusion models for double-ended queues with renewal arrival processes

open access: yesStochastic Systems, 2015
We study a double-ended queue where buyers and sellers arrive to conduct trades. When there is a pair of buyer and seller in the system, they immediately transact a trade and leave.

Dynamic scheduling for parallel server systems in heavy traffic: Graphical structure, decoupled workload matrix and some sufficient conditions for solvability of the Brownian Control Problem

open access: yesStochastic Systems, 2016
We consider a dynamic scheduling problem for parallel server systems. J. M. Harrison has proposed a scheme for using diffusion control problems to approximately solve such control problems for heavily loaded systems.

Spatiotemporal dynamics of traffic bottlenecks yields an early signal of heavy congestions

open access: yesNature Communications, 2023
Heavy traffic jams are difficult to predict due to the complexity of traffic dynamics. Understanding the network dynamics of traffic bottlenecks can help avoid critical large traffic jams and improve overall traffic conditions.

Conjectures on symmetric queues in heavy traffic

open access: yesQueueing Systems, 2022
This note describes several open questions concerning scaling limits of queue-length processes of symmetric queues in heavy traffic, distinguishing between service-time distributions with finite and infinite variance.

On Little’s Formula in Multiphase Queues

open access: yesMathematics, 2021
The structure of this work in the field of queuing theory consists of two stages. The first stage presents Little’s Law in Multiphase Systems (MSs). To obtain this result, the Strong Law of Large Numbers (SLLN)-type theorems for the most important MS ...

Metro Traffic Prediction and Service-Oriented Scheduling Optimization Under Influence of Train Arrivals

open access: yesIEEE Access, 2019

On Queues in Heavy Traffic

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1962
SUMMARY We say that a single server queue is in “heavy traffic” when the traffic intensity p is less than, but very near, unity. Then the equilibrium waiting time w will be large, and it is proved that, under certain conditions, the distribution of (1 – p)w tends, as p tends to 1, to a negative exponential distribution.
