基于知识元和有色Petri网的应急实施流程优化方法

A Method for Optimization of Emergency Rescue Process Based on Knowledge Element and Petri Net Theory

合理的应急实施流程对于有效应对突发事件至关重要。在知识元理论与Petri网方法的基础上提出了一种突发事件应急实施流程的优化方法。首先,借鉴共性知识模型,形式化表示活动基元及其内部联系,建立活动基元模型。随后,找到活动基元模型与有色Petri网的映射关系,并使用有色Petri网方法实现活动基元模型以及活动基元间的基本路由关系。在此基础上,结合知识元原理和Petri网方法,提出突发事件应急实施流程的五步优化方法。最后,以化学危险品事故为例说明该优化方法的使用过程。

Reasonable emergency response process is essential for dealing with emergencies effectively. This paper presented an optimization method of emergency rescue process based on the knowledge management and Petri net theory. At first,this paper formally indicated the activity unit and its internal relation,and established the activity unit model according to the common knowledge model. Then,the mapping from activity unit model to Petri net was discovered. Petri net was illustrated to realize common knowledge model and execution sequence relation among activity units. Based on this,a five- step optimizing method on implementation process of emergent event was provided by knowledge element theory and Petri net methodology. Finally,a dangerous chemicals accident was presented to demonstrate the implementation process of the proposed method.
