Preliminary Research On Scene-Oriented Evacuation Simulation

With the development of modern society, the requirements for disaster emergency management and designing in architecture are more and more rigorous; this is a challenge to evacuation simulation. This dissertation put forward two kinds of implement methods, and study multi-scale in evacuation scene by the view of scene-oriented; aiming at small-scale scene like architecture inner, put forward spatial-partition based evacuation simulation method, and realize crowd evacuation decision-making algorithm based on spatial-partition; aiming at large-scale scene like a disaster city, multi-network evacuation simulation is put forward; lastly, study multi-scale campus evacuation simulation system and evacuation simulation demo platform. The main contents are listed as follows:1. Scene-Oriented Evacuation Simulation:Two kinds of implement methods S-W ( Single-Whole ) and W-S (Whole-Single) are put forward, evacuation simulation method is analyzed in the view of scene-oriented, and multi-scale framework about evacuation scene is put forward.2. Spatial-partition Based Evacuation Simulation:This dissertation studies psychological and behavior characters in evacuation crowd, put forward partition principles based on apperception, builds crowd evacuation decision-making algorithm based on apperception, on the ground of scene model based on spatial-partition. Examples and analysis about the algorithm are presented.3. Evacuation Simulation in city disaster:This dissertation uses scene model based on network and multi-network simulation to fit the requirements of disaster evaluation. Examples and analysis about the algorithm are presented.4. Evacuation Simulation in multi-scale:This dissertation study multi-scale campus evacuation simulation, andrealizes evacuation simulation demo platform.
