Simulation on Evacuation of Underground Construction Using Extended-Cellular Automaton

The dynamic underground evacuation process during disaster was studied by the extended cellular automata(ECA) model.By the tool of Repast and cellular automata(CA) theory,the neighborhood of ECA model is extended and the heterogeneity is introduced into agents′ different behaviors,to simulate the process of evacuation.The results show: based on extended neighborhood of ECA model,both the mobility and agent′s ability to spread and receive information have significant influence;for the moderate mobility and agent′s ability,the evacuation efficiency is maximum and evacuation time is minimum.
