摘要通过将人际关系视为网络，灾难应对规划者可以捕捉到居民之间合作行为的特征，为有效的疏散规划提供有价值的见解。在这篇文章中，作者概述了2011年日本东部大地震以及由此引发的核灾难和海啸期间居民的疏散行为。对这些疏散行为的分析表明，居民之间的合作以及由两种类型的偏差造成的问题的重要性：常态和多数同步。接下来，描述了居民的合作行为是如何累积形成合作网络的，并将适应度模型应用到这些网络的形成中。给出了2004年尼哈马市泥石流灾害网络形成的实例研究。根据适应度参数的分布，对适应度参数进行了估计，分析了网络的形成过程和结构，并给出了网络的无标度特性。
AbstractBy treating human relationships as networks, disaster response planners can capture the features of cooperative behaviors between residents, providing valuable insights for effective evacuation planning. In this paper, the writers outline residents’ evacuation behaviors during the 2011 Great East Japan earthquake and the resulting nuclear disaster and tsunami. An analysis of these evacuation behaviors shows the significance of cooperation between residents and of problems caused by two types of bias: normalcy and majority syncing. Next, the writers describe how residents’ cooperation behaviors accumulate to form cooperation networks and apply the fitness model to the formation of these networks. A case study of network formation in response to a mudslide disaster in the city of Niihama in 2004 is provided. The writers estimate the fitness parameters and analyze the network formation process and structure on the basis of the distribution of the fitness parameters and show the scale-free characteris...
