摘要
航空事故大多是由诸多诱发因素紧密耦合、复杂交互导致的结果,为克服传统事故分析方法仅能处理单纯组件失效诱发的事故或相对简单的系统的不足,提出一种基于功能共振事故模型的航空事故分析方法。利用该方法,对美国5191航班冲出跑道事故进行系统分析。识别功能模块,评价功能性能变化,确定功能共振,并制定性能变化的防控屏障。结果表明:用该方法不仅能识别出导致事故的功能共振及其影响因素,解释事故发生的原因和过程,而且能够提出降低事故风险的防控措施。
The aviation accidents result mostly from close coupling and complex interactions between many inducing factors.However,the traditional accident analysis methods are only suitable for the accidents that the pure component failure leads to and the relatively simple systems.To overcome the shortcoming of the traditional accident analysis methods,an aviation accident analysis method based on functional resonance accident model was worked out.The method was used to analyze the accident that America flight 5191 overshot the runway.The process includes： identification of function modules,evaluation of performance variability for function modules,determination of functional resonances,and establishment of barriers for performance variability.The analysis results show that the method can not only identify the functional resonances leading to the accident and their influence factors,and explain the reasons and processes that the accident happened,but also provide the control measure to reduce accident risk.
