当前突发事件应急管理研究已经成为热点问题。本文针对突发事件及事件链研究特点,运用系统工程理论论,建立了突发事件及其链式关系知识表示模型。该模型从突发事件机理出发描述应急管理过程的知识需求,不仅揭示了突发事件发展、演变的行为模式及突发事件链式关系形成机理,还为应急决策提供理论依据,最后给出模型的应用实例,实现了事件演进的自动生成及应急过程中的知识支持。
The current emergency management research has become a hot issue. In this paper, according to the research characteristics of emergencies and event chains, this paper establishes the knowledge representation model of emergencies and their chained relations using the theory of systems engineering. The model describes the knowledge needs of emergency management process from the mechanism of emergency, which not only reveals the behavior of emergency development and evolvement, but also provides the theoretical basis for emergency decision-making. Finally, the model The application examples are given to realize the automatic generation of event evolution and the knowledge support in the emergency process.
