Gordon and Newell queueing networks and copulas
In this paper we have found an analytical formula for a copula that connects the numbers Ni of customers in the nodes of a Gordon and Newell queueing network.

Velocity‐based stowage policy for a semiautomated fulfillment system
Production and Operations Management, EarlyView., 2022 Abstract Online retail fulfillment is increasingly performed by semiautomated fulfillment systems in which inventory is stored in mobile pods that are moved by robotic drives. In this paper, we develop a model that explores the benefits of velocity‐based stowage policies for semiautomated fulfillment systems, also known as robotic mobile fulfillment ...

HEAVY TRAFFIC ANALYSIS IN QUEUEING SYSTEMS
Studia Universitatis Moldaviae: Stiinte Umanistice, 2008 The traffic intensity is defined in the classical theory of queueing systems as the ratio of the expected service time and the expected interarrival time and is an important measure of the system performance.

Distributed computing for the reconstruction of multi‐terabyte tomographic X‐ray imaging datasets
Journal of Synchrotron Radiation, EarlyView.As tomographic datasets from synchrotrons continue to increase in volume, so rises the challenge of reconstructing said data. Here we present a solution utilizing high‐performance computing capabilities to split the process into multiple smaller tasks, which can be solved without overwhelming a single compute node.

Queueing and Markov chain decomposition method to analyze Markov-modulated Markov chains
, 2021 We present a Queueing and Markov chain decomposition method based on the total expectation theorem. Our decomposition method requires partial flow to be conserved, which we call a termination scheme.

What England Is and What It Claims to Be: Orwell on National Identity
The Political Quarterly, EarlyView.Abstract This article suggests that George Orwell's body of work offers a rather unique and insightful two‐part conception of national identity in the context of England, made up of a moral inheritance—the values of liberty, fairness and decency—and a lived sensibility—the fluid, experiential quality of collective life expressed in shared customs ...

Strategic Queueing Behavior of Two Groups of Patients in a Healthcare System
MathematicsLong waiting times and crowded services are the current medical situation in China. Especially in hierarchic healthcare systems, as high-quality medical resources are mainly concentrated in comprehensive hospitals, patients are too concentrated in these ...

STABILITY OF THE CRITICAL QUEUEING SYSTEMS
Journal of the Operations Research Society of Japan, 1982 This paper considers the stability of the waiting time in the queueing system with the critical condi- tion: ESi = sETi. It is shown that the waiting time is stable in the model with special moving average input and the unstability condition is obtained in the strictly stationary input with the finite variance.
