基于情景的突发事件链构建方法

A Scenario-based Construction Method of Emergency Event Chain

突发事件前兆缺失,危害巨大,其次生、衍生事件构成的事件链给人类造成严重的影响。针对突发事件演变路径不明,形成的链式结构复杂多变的特点,借鉴共性知识模型,利用知识元刻画情景与事件,通过知识元间的关联,分析情景与事件相互作用关系,事件间的演变规律;以数据和规则为驱动,提出了一种基于情景的突发事件链构建方法,该方法可为"情景-应对"决策提供了支持,最后给出案例分析。

Lacking of precursor, emergency events do harm to human society greatly. Emergency event chain, constituted by secondary e- vents, has severe negative effects on human race. The chain structure of emergency event is complex and varies frequently, and it is diffi- cult to judge the evolution path for emergency events. Drawing on the common knowledge model, using knowledge element to express scenario and events, the paper analyzes the interaction between scenario and events and the evolution of events based on the relationship of knowledge element. Using data and rule as drive, a scenario-based construction method of emergency event chain is proposed. The meth- od supports ＂scenario-response＂ policy decision-making. At last, a case study is presented.
