摘要

The present invention relates to a method and a device for human evacuation simulation, a method and a system for decision-making assistance, and an emergency platform. The human evacuation simulation method performs human evacuation simulation in unit of community consisting of a plurality of buildings, comprising: abstracting every building in the community as one network node, and performing, in parallel, evacuation simulation on a plurality of nodes in the community; dividing the evacuation process in each node into an evacuation reaction process, a walk process, and a congestion process in series, and calculating the evacuation time in the node; searching, among all the network nodes in the community, a first node in which the evacuation time is longest; and determining, according to the evacuation time of the first node, the total evacuation time of the entire community. The present invention is able to achieve evacuation with a community as a unit, requiring less parameter to be inputted, having a high computing speed, and being applicable into practical emergency decision making.
