【 摘 要 】

Existing ant colony evacuation path optimization models seldom consider the degree of population chaos and the evacuation status under different classifications of population. Based on the modified ant colony evacuation model of evacuation entropy, this paper establishes models for calm, sensitive and managed crowd respectively. The behavior characteristics of different classified groups in real evacuation scenarios are simulated through modifying its state transition probability and global pheromone updating method. It is of important practical significance for the path optimization in public safety emergency management.
