DEVS-based Building Information Modeling and simulation for emergency evacuation

Nowadays, numerous Computer-aided Design (CAD) software packages support Building Information Modeling (BIM). BIM software can benefit of advanced simulation in the pre-design phase of construction projects. In this case, we show focus on models of the emergency evacuation regarding the security and safety. We analyze the evacuation simulation of a model based on DEVS (Discrete Event systems Specification) for BIM authoring tools. The idea is to automate to extraction of building information that can be subsequently used in a simulation. Our case study uses a Cell-DEVS model of the evacuation of a multi-floor building. We also show how to obtain a 3D visualization by transforming the simulation results, facilitating the work of architects, contractors and fabricators. This kind of application could be used to analyze bottlenecks and the maximum occupation for determining an optical evacuation plan.
