摘要/Abstract

摘要： 为预防石化工业储罐区火灾触发的多米诺效应,首先,构建基于层次着色时间Petri网(HCTPN)的储罐火灾应急响应模型,以库所表示状态或指令,以变迁表示应急响应行动,以托肯的移动表示系统的动态变化;其次,提出5种不同的时间模式,包括时间串行门、时间输出与门、时间输入与门、时间输出或门和时间输入或门,分析该模型的时间性能;最后,以某储罐火灾为例,通过CPN Tools仿真分析应急响应时间,评估多米诺效应发生的概率,并通过讨论2种场景探究应急响应行动的协作对多米诺效应的影响。结果表明:应急行动的并行模式比串行模式更省时间、更能预防多米诺效应;用所构建模型能有效地分析应急响应行动的时间性能。

Abstract: In order to prevent domino effect triggered by fire in tank areas of petrochemical industry,an HCTPN based model was built for analyzing emergency actions responding to tank fires.The states of emergency response were represented by places,emergency actions by transitions,and changes of emergency states by flow of tokens in the net.Then,five different time patterns time serial gate,time output AND gate,time input AND gate,time output OR gate and time input OR gate,were proposed to analyze the time performance of the model.Finally,a tank fire was taken as an example,and the emergency response times were analyzed by using by the CPN Tools.The probabilities of domino effects were evaluated through the simulation analysis of the emergency response times.Two scenarios were discussed to analyze the impact of collaboration of emergency actions on fire escalation.The results show that the parallel mode of emergency actions is more time-saving and can prevent domino effect better than the serial mode,and that the model can be used to effectively analyze the time performance of emergency actions.
