摘要：

针对当前研究成果较少考虑到事件演进中属性间的关联关系、缺乏对事件及事件链的结构化描述及未从属性视角考虑应急决策等现状,在运用多案例分析给出事件链的结构化描述模型的基础上,通过定义活跃属性,运用超图理论建立非常规突发事件链的超网络模型,并构造其投影网络模型。进而提出节点和边的重要性判别准则,给出同类边、异类边、同类度、异类度和关联矩阵的定义。然后,运用结构洞理论提出节点的重要性、边的重要性和网络关联度的评估方法。最后,以2008年汶川大地震的事件链为例进行案例研究,验证了理论研究的有效性。

Abstract:

Few of existing studies pay attention to the interrelations of different attributes during the process of emergency evolution, structural description of unconventional emergency chain, or emergency decision-making from the perspective of attributes. This paper first presents the structural description model of unconventional emergency chain. Then, based on hypergraph theory, we define active attributes and establish both the unconventional emergency chain hypernetwork model and its projection network model. Next, the criterions for the importance of network nodes and edges are put forward after making definitions of homogeneous edge, heterogeneous edge, homogeneous degree, heterogeneous degree and correlation matrix, so as to propose an assessment approach of importance of node, edge and network connectivity. Finally, Wenchuan earthquake in 2008 is taken as an example to verify the validity of this study.

Key words: unconventional emergency chain, hypernetwork, structural hole, connectivity
