应用扩展元胞自动机(ECA)模型,研究灾害发生时地下建筑中人员动态疏散过程.利用Repast模拟工具,结合元配自动机理论,基于扩展的冯诺依曼邻域范围,引入异质行为与疏散过程中人群的不同状态,对地下建筑的人员疏散进行模拟.模拟结果表明:在扩展的摩尔邻域下,个体的活跃程度、信息的接受能力与传递能力对地质灾害发生时地下建筑人员的疏散效率有显著影响;当个体的活跃程度,信息接受能力与传递能力适中时,有最大疏散效率,所需的疏散时间最短.
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 agentsr different behaviors, to simulate the process of evacuation. The results show: based on extended neighborhood of ECA model, both the mobility and agentrs 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.
