Two-types of service facilities in interconnected stochastic queueing and queueing-inventory system with marked Markovian arrival process

Ain Shams Engineering Journal
This article explores the performance of interconnected queueing systems and queueing-inventory systems (IQSQIS) in stochastic modeling. IQSQIS features two types of service facilities with dual service stations: one providing non-commodity service with ...

Towards Characterization of Five‐List‐Colorability of Toroidal Graphs

Journal of Graph Theory, EarlyView.
ABSTRACT Through computer‐assisted enumeration, we list minimal obstructions for 5‐choosability of graphs on the torus with the following additional property: There exists a cyclic system of non‐contractible triangles around the torus where the consecutive triangles are at distance at most four.

Large closed queueing networks in semi-Markov environment and its application

, 2007
The paper studies closed queueing networks containing a server station and $k$ client stations. The server station is an infinite server queueing system, and client stations are single-server queueing systems with autonomous service, i.e.

Decision Threshold Setting in Binary Classification Problems—A Behavioral Lens

Journal of Operations Management, EarlyView.
ABSTRACT When binary classification models are wrong, managers face misclassification costs. Although false positive outcomes imply unnecessary mitigation efforts, false negative outcomes imply overlooking the class of interest. Humans calibrate these ai models supporting operational systems by adjusting the decision threshold that translates ...

DISTRIBUSI POISSON DAN DISTRIBUSI EKSPONENSIAL DALAM PROSES STOKASTIK

Media Statistika, 2011
In the queueing system, the processes usually come from a Poisson process. In this system should be obtained an arrival distribution and a service distribution.

From Offline to Inline Without Pain: A Practical Framework for Translating Offline MR Reconstructions to Inline Deployment Using the Gadgetron Platform

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and validate a practical, open‐source framework to overcome common issues in inline deployment of established offline MR reconstruction, including (1) scan disruption from lengthy reconstructions, (2) limited support for multi‐scan input reconstructions, (3) needs to adapt scripts for different raw‐data formats, and (4 ...

Multi‐Agent Reinforcement Learning for Joint Police Patrol and Dispatch

Naval Research Logistics (NRL), EarlyView.
ABSTRACT Police patrol units need to split their time between performing preventive patrol and being dispatched to serve emergency incidents. In the existing literature, patrol and dispatch decisions are often studied separately. We consider joint optimization of these two decisions to improve police operations efficiency and reduce response time to ...

Queues with resetting: a perspective

Journal of Physics: Complexity
Performance modeling is a key issue in queuing theory and operation research. It is well-known that the length of a queue that awaits service or the time spent by a job in a queue depends not only on the service rate, but also crucially on the ...

Heavy-traffic limits for a fork-join networkin the Halfin-Whitt regime

Stochastic Systems, 2016
We study a fork-join network with a single class of jobs, which are forked into a fixed number of parallel tasks upon arrival to be processed at the corresponding multi-server stations.

Living Well With Type 1 Diabetes in Middle School: A Student‐Centered Perspective

Psychology in the Schools, EarlyView.
ABSTRACT Type 1 diabetes (T1D) is among the most common chronic illnesses affecting children and adolescents, meaning that all schools regularly include students with T1D. Supporting their well‐being requires understanding how they experience middle school to address their specific needs.
