Comparison Between The Human Reactions In A Simulacrum And In A Real Fire Situation

May 22, 2018
Human reaction to a fire situation in buildings depends on the characteristics of each individual, of the building and the actual emergency situation. To minimize the consequences of an emergency fire situation in a building, it is important to have a safe, orderly and rapid evacuation. For this purpose, the occupants should be trained to respond in an appropriate way. Therefore, it is necessary to assess whether simulacrums or fire drills are effective or not. Read More...

Change Behavior in Pathfinder

May 16, 2018
As of Pathfinder 2018.2, Behaviors can now dynamically change from one to another throughout the simulation. The new Change Behavior step allows the user to define a progression to one of the other Behaviors defined in the model. Read More...

The Simulation Of Assisted Evacuation In Hospitals

April 2, 2018
This paper proposes a modelling strategy to simulate a hospital evacuation. The capabilities of two commercial evacuation models, STEPS and Pathfinder, are explored to evaluate their ability to simulate this type of scenarios. This includes the study of the issues concerning the simulation of horizontal hospital evacuation (i.e. calibration issues, capabilities and limitations). A case study is presented in this paper by using STEPS model. Read More...
