本文依据中国民用航空安全信息网上近五年来业界所有不安全事件的数据,将数据按原因分类,运用灰色关联理论分析方法,对各原因的重要度进行关联度分析。结果表明:与不安全事件相关的因素主要有三点,即机组失误、地面保障、天气原因,其中机组失误与不安全事件的发生关系最为密切;地面保障因细节较多,其关联程度也较大;由于天气原因的不确定因素较多,也应成为采取预防措施的关键入手点。论文最后针对分析所得的三点关键因素,提出了相应的预防和减少不安全事件发生的建议。
Based on the data of all the unsafe incidents in the industry of China Civil Aviation Safety Information Network in recent five years, this paper classifies the data according to the causes and uses the gray relational theory analysis method to analyze the degree of importance of each reason. The results show that there are three main factors related to unsafe events, namely, unit failure, ground support and weather, of which unit error is most closely related to the occurrence of unsafe incidents; ground support is more related due to more details ; Due to the more uncertainties of the weather, it should also be a key starting point for taking precautionary measures. At the end of the thesis, according to the three key factors analyzed, we put forward the corresponding suggestions to prevent and reduce the occurrence of unsafe incidents.
