| 摘 要： | QAR超限是航空运输的一大类安全隐患,本文综合运用Copula函数和Logistic回归建立飞行操作的风险分析模型。结合模型特点设计进化算法,实现对飞行操作状态空间的搜索,通过模型寻优过程找到QAR超限的高风险操作。对航空公司一类重点监控QAR超限的实证研究,得到易导致该类超限的高风险操作,为飞行员针对性训练提供了量化依据。

| Abstract: | QAR exceedances axe hidden danger to air transportation.This paper combines copula with logistic regression to establish risk analysis model of operations in flight.According to optimal objectives of the model,we design evolutionary algorithm to explore operations state space,in order to find the sub-space with higher exceedance frequency.Through empirical study of a specific QAR exceedance,we find some high risk operations associated with it.These results give a basis for pilots’ special training. |
