Published: 2021/01/31, Updated: 2021/02/02

Applications - OR and Management Sciences, Integer Programming, Optimization of Simulated Systems derivative-free optimization, discrete event simulation, emergency department, model calibration, simulation-based optimization

Accurate modeling of the patient flow within an Emergency Department (ED) is required by all studies dealing with the increasing and well-known problem of overcrowding. Since Discrete Event Simulation (DES) models are often adopted with the aim of assessing solutions for reducing the impact of this worldwide phenomenon, an accurate estimation of the service time … Read more

Determining the optimal piecewise constant approximation for the Nonhomogeneous Poisson Process rate of Emergency Department patient arrivals

Published: 2021/01/25, Updated: 2021/01/31

Applications - OR and Management Sciences, Integer Programming arrival process, blackbox optimization, emergency department, non homogeneous poisson process

Modeling the arrival process to an Emergency Department (ED) is the first step of all studies dealing with the patient flow within the ED. Many of them focus on the increasing phenomenon of ED overcrowding, which is afflicting hospitals all over the world. Since Discrete Event Simulation models are often adopted with the aim to … Read more
