An effective and efficient matheuristic for the electric vehicle routing problem with capacitated recharging stations

International Transactions in Operational Research, EarlyView.
Abstract In this paper, we address the problem of routing a fleet of electric vehicles (EVs) to serve a set of customers, geographically distributed, within their time windows. We assume that EVs may also be recharged en route, and the amount of energy recharged at a recharging station (RS) is a decision variable itself, that is, partial recharges are ...

Vessel arrival planning with full information

International Transactions in Operational Research, EarlyView.
Abstract Planning efficiency and timely arrival of vessels is crucial to smooth operations of maritime transport networks, ensuring optimal utilization of resources and minimizing operational costs. Coordination between vessel operators and terminals has the potential to reduce costs, fuel consumption, and waiting time.

A Cross-sectional Study of the Blood Sample Collection Center Using Queuing Theory at a Tertiary Care Hospital

Journal of Marine Medical Society
Introduction: Queuing theory, originating with Agner Krarup Erlang in 1908, has evolved to address healthcare operations, notably in managing outpatient appointments and hospital services. Its application helps hospitals optimize service capacity, reduce

Application of Queuing Theory in a Canteen

Revista do Encontro de Gestão e Tecnologia
Los comedores escolares son lugares que proporcionan alimentos esenciales para que los alumnos puedan cubrir sus necesidades nutricionales y, en consecuencia, mantener su energía para aprovechar mejor las clases. Debido al corto tiempo de pausa y a los posibles picos de demanda, el servicio en el establecimiento acaba formando una cola.

Lost in the Noise: How IPO Suspensions Distract Venture Capitalists From Monitoring Portfolio Firms

Journal of Business Finance &Accounting, EarlyView.
ABSTRACT We examine how regulatory suspensions of initial public offerings (IPOs) affect venture capitalists’ (VCs’) post‐IPO monitoring of portfolio firms in China. Using a difference‐in‐differences design that exploits three major IPO suspension episodes as quasi‐natural experiments, we provide causal evidence that these shocks divert VCs’ attention ...

Telemedicine Queuing System Study: Integrating Queuing Theory, Artificial Neural Networks (ANNs) and Particle Swarm Optimization (PSO)

Applied Sciences
Telemedicine has emerged as a vital tool for expanding healthcare access, particularly in underserved areas, yet its effectiveness is often hindered by inefficient queuing systems, fluctuating patient demand, and limited resources.

Rational acquisition of laboratory equipment: an accurate mathematical model to estimate the trade-offs in shared and nonshared equipment. [PDF]

Acta Crystallogr D Struct Biol
We present a quantitative framework combining cost modelling and queueing theory to estimate hourly access costs, waiting times and congestion levels for shared high‐end scientific equipment. The approach is general, illustrated with cryo‐electron microscopy examples, and implemented in an open‐access online calculator to support evidence‐based ...
