Research on a Hybrid Simulation Model of Building Fire Evacuation

Nowadays, the structures of buildings are increasingly huger and the layouts become more and more complex. How to ensure evacuees get away from the fire environment safely has become a hot topic in the research of fire safety engineering. In this paper, we built a hybrid simulation model based on environmental model (ESM) and pedestrian model (PSM) to solve this problem, and improved the model by CA. We introduced the outlet width, aisle attraction factor and the field temperature into the model and get optimal solutions-shorter evacuation time. The simulation results of two kinds of aisle attraction modes show that the pedestrian model based on multi-agent which regarded individuals as autonomous agents could fully reflect the differences and intelligence of the crowds in the real world.
