摘　　要：在传统社会力模型中引入小群体领导力参数,修正疏散过程小群体成员的运动方向与运动速度。基于改进的社会力模型进行Agent建模,利用Anylogic得到计算结果,统计分析不同小群体规模、小群体占总人数比例及小群体会合地点情况下小群体成员的疏散时间,研究小群体行为参数对疏散时间的影响。结果表明:小群体规模越大、占总人数比例越高、会合地点越接近房间中部,疏散时间越长。The leadership parameter of small group was introduced into the traditional social force model to modify movement direction and speed of small group members in the evacuation process.The Agent model was established based on modified social force model and the calculation was carried out by Anylogic.Then evacuation time of small group members in conditions of different small group size,the proportion of small group members in whole occupants and the meeting place were statistically analyzed.The influence of the above small group behavior parameters on evacuation time was obtained.The results indicated that larger small group size,higher proportion of small group members in whole occupants and closer distance from the meeting place to the middle of the room can all result in longer evacuation time.

关 键 词：改进社会力模型 AGENT建模 小群体行为 疏散时间
