Experimental evidence of the “Faster is Slower” effect in the evacuation of ants
(Elsevier, 2012-04)
The faster is slower effect is a self-organized phenomena first described for pedestrian dynamics. Although it has been obtained in computer simulations, it has not been observed in real systems yet. To achieve this goal, ...
Pedestrian collective motion in competitive room evacuation
(Nature Publishing Group, 2017-12)
When a sizable number of people evacuate a room, if the door is not large enough, an accumulation of pedestrians in front of the exit may take place. This is the cause of emerging collective phenomena where the density is ...
Pedestrian flows through a narrow doorway: Effect of individual behaviours on the global flow and microscopic dynamics
(Pergamon-Elsevier Science Ltd, 2017-05-20)
We study the dynamics of pedestrian flows through a narrow doorway by means of controlled experiments. The influence of the pedestrians’ behaviours is investigated by prescribing a selfish attitude to a fraction cs of the ...
Flow of pedestrians through narrow doors with different competitiveness
(IOP Publishing, 2016-04)
We report a thorough analysis of the intermittent flow of pedestrians through a narrow door. The observations include five different sets of evacuation drills with which we have investigated the effect of door size and ...
A counterintuitive way to speed up pedestrian and granular bottleneck flows prone to clogging: can 'more' escape faster?
(IOP Publishing, 2018-08)
Dense granular flows through constrictions, as well as competitivepedestrian evacuations, are hindered by a propensity to form clogs. We use simulations of model pedestrians and experiments with granular disks to explore ...
Efficient Egress of Escaping Ants Stressed with Temperature
(Public Library of Science, 2013-11)
In the present work we investigate the egress times of a group of Argentine ants (Linepithema humile) stressed with different heating speeds. We found that the higher the temperature ramp is, the faster ants evacuate ...
Simulating competitive egress of noncircular pedestrians
(American Physical Society, 2017-04)
We present a numerical framework to simulate pedestrian dynamics in highly competitive conditions by means of a force-based model implemented with spherocylindrical particles instead of the traditional, symmetric disks. ...
La coordinación inter-organizacional en los procesos logísticos de preparación de emergencias y desastres.
(Universidad Nacional de ColombiaManizales - Ingeniería y Arquitectura - Doctorado en Ingeniería - Industria y OrganizacionesDepartamento de Ingeniería IndustrialFacultad de Ingeniería y ArquitecturaManizales, ColombiaUniversidad Nacional de Colombia - Sede Manizales, 2021)
Ante los registros crecientes de desastres naturales acaecidos a nivel global, junto con otras amenazas que afronta la humanidad en la actualidad, como el aumento incontrolado de la población, los fenómenos de cambio ...

Localización de instalaciones y ruteo de personal especializado en logística humanitaria post-desastre - caso inundaciones
(Universidad de La SabanaMaestría en Gerencia de OperacionesEscuela Internacional de Ciencias Económicas y Administrativas, 2015-03-21)
La cadena de suministro en la logística humanitaria puede describirse como una red de personal voluntariado y especializado que interactúa con un conjunto de bienes y servicios, esto con el propósito de satisfacer la demanda ...
