本文对离散时间动态网络模型在社区疏散问题中的应用进行了研究。时间是模型中都的主要参数,其中在社区各组成部分中行走的时间只是总疏散时间的一部分。模型中把疏散时间划分为时间周期,反映了疏散者的运动随时间变化的情况。在不考虑紧急情况下人任何的个体行为的情况下产生一个疏散时间的下限(即最小疏散时间)。这一数值可用来对现存社区的疏散能力进行分析或评估。 This paper studies the application of discrete-time dynamic network model in community evacuation. Time is the main parameter in the model, and the time it takes to walk among the components of the community is only part of the total evacuation time. In the model, the evacuation time is divided into time periods, which reflects the evacuation movement of evacuees over time. A minimum time of evacuation (ie minimum evacuation time) is created without regard to any individual behavior in an emergency. This value can be used to analyze or assess the evacuation capacity of existing communities.
