The Research of Multi-Resolution Modeling and Simulation of the Emergency Evacuation

During emergency evacuation, there will be enormous security problem. It is an important field to lucubrate the crowd dynamic in evacuation. The research of evacuation modeling and simulation is widely developed with the development of computer simulation. The theory and method of Multi-Resolution Modeling provide a new way to simulate the crowd dynamics. In this paper, based on the theory of complex system, with the multi-resolution modeling and method, two kinds of resolution model on pedestrian evacuation and simulation have been presented. One is based on Multi-Agent framework and a modified PSO algorithm. The other is based on the Euler equations of fluid dynamics. The case study of pedestrian flow simulation in Optical Valley Plaza is explored thoroughly by using the fluid dynamic equation. The aggregate/ disaggregate algorithm of multi-resolution model is presented to implement the interaction and parallel computing of the micro simulation model and the macro simulation model.
