一种考虑内在状态的紧急撤退模型

An Evacuation Model with the Conception of Internal State

将内在状态引入了所建的紧急撤退模型。使出用内心镇静值和当前狂躁值来区分撤退过程中个体的镇静和慌乱两种心情,不同心情下个体执行不同的行为控制。提出了影响个体活力值的三条规则,再现了在慌乱撤退中人们相互冲撞以至丧失逃生能力的现象。仿真结果表明,内在状态的引入使原有模型更趋合理慌乱人群的撤退速度将快于镇静的人群,代价是出现撤退失败的个体。分析了镇静值,撤退速度,失败个体比重三者间的关系,并讨论了少数慌乱者对整个人群撤退结果的影响。

The conception of internal state is introduced into the evacuation model constructed in this paper. The state of calm is distinguished from that of anxiety in evacuation procedure by using calm value and anxiety value. Individual will use different behavior controlling according to different state. Three rules affecting individual＇s live value are presented, and the phenomena of losing ability of escaping because of bumping against one another are taken on in the evacuation procedure. The simulation results show that the introduction of interual state makes the original model more reasonable ： evacuating velocity of anxiety crowd is faster than that of calm group, with appearance of ones failing the evacuation as a price. The relationship among calm value, evacuating velocity and the proportion of failed ones is analyzed. And the effect of a few anxious ones on evacuation result of the whole crowd is discussed.
