摘　　要： 通过将分区疏散转化为分配问题(Allocation Problem),并采用启发式的A*优化算法,对人员位置固定的公共场所分区疏散进行研究。进一步利用基于元胞自动机模型的大型公共场所人员疏散行为模拟仿真系统,在充分考虑公共场所中每个人员的状态、人员之间以及人员与周围环境的相互作用的前提下,对疏散分区的效果进行模拟;通过与未分区的模拟结果相比较,可以认为,分区疏散有助于人员快速疏散,大大缩短整体避难时间,而且基于移动路径搜索的分区更加切合实际。 This paper firstly adopts A^＊ heuristic optimization algorithm to study the partition evacuation in public places with people＇s position fixing through translating partition evacuation into allocation problem. Then, by use of man evacuation behavior simulation system based on cellular automation model and by taking full consideration of the state of personnel, the interaction among them and the interaction with environment, the effect of partition evacuation is simulated. Comparing with the result obtained by nonpartition evacuation simulation, the result shows that partition evacuation can be very helpful to quick evacuation, greatly shorten the time of taking shelter, and be more practical if it is based on moving route search.
