空中交通管制是航空安全的重要保障,为有效避免空管不安全事件的发生,找出导致不同等级空管不安全事件的风险因素并提出针对性的控制措施,根据某管制中心发生的不安全事件信息,结合其严重性等级进行风险管理研究.首先对该管制中心进行风险识别,在统计并分析其2001-2010年不安全事件的数据后,选择SHEL模型按照人员(L)、人员与人员(L-L)、人员与软件(L-S)、人员与硬件(L-H)和人员与环境(L-E)方面系统地识别出风险因素集;在此基础上,运用灰色关联分析进行定量评价,得出不同等级不安全事件风险因素评价结果;最后根据评价结果制定出不同等级不安全事件相应的风险控制措施.%Air traffic control is essential for the safety of aviation; in order to avoid the happening of unsafe events of air traffic control effectively, find the risk factors which lead to different level of unsafe events and make corresponding risk control measures, the information of unsafe events which happened in the air traffic control center was combined with the level of severity to implement risk management. Firstly risk identification was carried out to an air traffic control center. After the statistics of the unsafe events which happened from 2001 to 2010 in this air traffic control center was analyzed, the SHELL model was selected as the risk identification tool. Air traffic control risk factors was classified and analyzed in accordance with Life (L) factors/Life and Life (L-L) factors/ Life and Software (L-S) factors/ Life and Hardware (L-H) factors/ Life and Environmental factors (L-E) factors to get the muster of risk factors; then grey correlation degree was used as the tool of risk assessment to quantitatively analyze the importance of risk factors of different level of unsafe events. Finally, based on the results of risk assessment, corresponding risk control measures of different level of unsafe events were made.
