Dynamic Physician Rostering in Emergency Departments: Managing Reentrant Patient Flows to Meet Excess Wait Time Targets. [PDF]

open access: yesHealth Care Sci
We develop a patient flow model that integrates return loops and formulate a risk‐aware physician rostering framework designed to strictly enforce excess wait time targets, for example, tail probability of delay (TPoD) service levels. We employ a simulation‐based iterative staffing approach (ISA) to determine the optimal number of physicians required ...

Queueing Theory-Based Mathematical Models Applied to Enterprise Organization and Industrial Production Optimization

open access: yesMathematics, 2022
In the paper, a new method was presented using queueing theory models in order to ensure an optimal production department size, optimized production costs and optimal provision. Queueing/waiting mathematical models represent the development matrix for an

Queues on interacting networks

open access: yesQueueing Systems, 2022
Interacting networks are different in nature to single networks. The study of queuing processes on interacting networks is underdeveloped. It presents new mathematical challenges and is of importance to applications. This area of operations research deserves careful study: queuing theory needs to incorporate high-order network interactions in the ...

Analysis of Closed Queueing Networks with Batch Service [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2020
We consider a closed queuing network with batch service and movements of customers in continuous time. Each node in the queueing network is an infinite capacity single server queueing system under a RANDOM discipline.

Calculation of time characteristics for acyclic fork-join queueing network [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика
An open acyclic fork-join queueing network is considered. When a job arrives from a source into the network, it is split to be serviced into a given constant number of associated tasks.

Optimal Scheduling in General Multi-Queue System by Combining Simulation and Neural Network Techniques

open access: yesSensors, 2023
The problem of optimal scheduling in a system with parallel queues and a single server has been extensively studied in queueing theory. However, such systems have mostly been analysed by assuming homogeneous attributes of arrival and service processes ...

Hardware acceleration of number theoretic transform for zk‐SNARK

open access: yesEngineering Reports, EarlyView., 2023
An FPGA‐based hardware accelerator with a multi‐level pipeline is designed to support the large‐bitwidth and large‐scale NTT tasks in zk‐SNARK. It can be flexibly scaled to different scales of FPGAs and has been equipped in the heterogeneous acceleration system with the help of HLS and OpenCL.

Could we employ the queueing theory to improve efficiency during future mass causality incidents?

open access: yesScandinavian Journal of Trauma, Resuscitation and Emergency Medicine, 2019
Background Preparation for a disaster or accident-related mass casualty events is often based on experience. The objective measures or tools for evaluating decision-making and effectiveness during such events are underdeveloped.
