基于 Petri 网的航母飞行甲板火灾评价方法*

摘要

The aviation support operations of flight deck are very complicated ,in which there are a lot of interactive risk factors ,and the fire accidents are often arising ,so all of these bring serious hidden troubles on personnel ,aircrafts and e‐quipments .Until now ,some risk assessment methods have become mature ,but these methods are hard to analyze fire risk quantitatively and dynamically .Based on summarizing the current fire risk assessment methods ,according to fire safety char‐acteristics of flight deck ,the object‐oriented Petri Nets is adopted to deal with fire risk assessment of flight deck ,and a method based on Petri Nets modeling and simulation is put forward .The proposed method has great meanings in analyzing fire risk of flight deck quantitatively .%航母飞行甲板上的航空保障作业极为复杂，各种危险源互相交织，极易发生火灾事故，给人员、舰载机和系统设备安全造成了很大隐患。目前，火灾风险的随机性评价方法虽比较成熟，但难以对其进行定量和动态分析。在综合当前火灾风险评价方法的基础上，针对航母飞行甲板的火灾安全特性，提出使用面向对象的 Petri网建模和仿真方法，进行飞行甲板火灾风险评价，并建立了相应的评价模型，为飞行甲板定量评价提供了重要支撑。
