Optimal Scheduling in General Multi-Queue System by Combining Simulation and Neural Network Techniques [PDF]
Sensors, 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 ...

Optimizing Cardiac Inpatient Flow and Resource Allocation in Low-Resource Settings Using Queuing Theory: Insights From a Tertiary Hospital in Bangladesh. [PDF]
Public Health ChallThis study applies queuing theory models (M/M/c/c and M/M/c/K) to optimize inpatient flow and resource allocation in the cardiology department of Sylhet MAG Osmani Medical College Hospital, Bangladesh. Using data from 6,277 patients in 2023, it identifies bottlenecks in CCU and PCCU, highlights bed shortages and overcrowding, and proposes reallocating ...

Some Single Valued Neutrosophic Queueing Systems with Maple Code [PDF]
Neutrosophic Sets and Systems, 2023 In this paper we introduce for the first time the concept of single valued neutrosophic queueing systems (SVNQSs) as an extension of crisp and fuzzy queueing systems which are very applicable and important in controlling systems. SVNQSs have been defined

Analysing Impatience in Multiserver Markovian Queues [PDF]
International Journal of Supply and Operations Management, 2020 Reneging and Balking are practical aspects of customer impatience. In traditional queuing literature, customer impatience was rarely considered. However, for the last few decades, queuing theorists have been trying to integrate aspect of balking and ...

Markovian inventory model with two parallel queues, jockeying and impatient customers [PDF]
Yugoslav Journal of Operations Research, 2016 This article presents a perishable stochastic inventory system under continuous review at a service facility consisting of two parallel queues with jockeying. Each server has its own queue, and jockeying among the queues is permitted.

Mathematics, 2023 We consider a non-standard class of Markovian time: varying infinite capacity queues with possibly heterogeneous servers and impatience. We assume that during service time, a customer may switch to the faster server (with no delay), when such a server ...

Performance Analysis of Hybrid MTS/MTO Systems with Stochastic Demand and Production
Mathematics, 2020 We present a comprehensive numerical approach with reasonably light complexity in terms of implementation and computation for assessing the performance of hybrid make-to-stock (MTS)/make-to-order (MTO) systems.

A Discussion on the Optimality of Bulk Entry Queue with Differentiated Hiatuses [PDF]
Operations Research and Decisions, 2022 We consider Markovian differentiated hiatuses queues with bulk entries. With the help of the matrix geometric method, we discuss the stability condition for the existence of the steady-state solution of our model and we obtain the stationary system size ...

On the rate of convergence for a class of Markovian queues with group services
Discrete and Continuous Models and Applied Computational Science, 2020 There are many queuing systems that accept single arrivals, accumulate them and service only as a group. Examples of such systems exist in various areas of human life, from traffic of transport to processing requests on a computer network. Therefore, our
