Abstract Emergency response plays an important role in preventing or delaying the domino effect of chemical accidents. Requirements for emergency response to a major accident may exceed the capacity of the emergency department within the region of responsibility for the accident, in which case multi-department emergency response is necessary. In this work, modeling problems related to the arrival of emergency teams at different times in multi-department emergency response are discussed. These problems will dynamically influence the time to failure of adjacent facilities in the event of a fire. A timed colored hybrid Petri-net (TCHPN) approach is proposed to solve these problems and analyze multi-department emergency response processes. An example of responding to a tank fire illustrates the proposed approach. An emergency response process is simulated, and probabilities of fire escalation prevention under different fire levels are analyzed.

多部门应急响应Petri网模拟避免化工事故多米诺骨牌效应

摘要 应急响应对于预防或延缓化学品事故的多米诺骨牌效应具有重要作用。对重大事故应急响应的要求可能超出事故责任区域内应急部门的能力,在这种情况下,需要多部门应急响应。在这项工作中,讨论了多部门应急响应中与应急小组在不同时间到达相关的建模问题。在发生火灾时,这些问题会动态地影响相邻设施的故障时间。提出了一种定时彩色混合Petri网(TCHPN)方法来解决这些问题并分析多部门应急响应过程。一个响应坦克火灾的例子说明了所提出的方法。
