摘要
针对空中交通管制班组安全行为的风险类型,在实地调研的基础上选取班组行为风险指标,结合层次分析法构建指标体系,并在风险危害因子及风险抵御因子的基础上,运用加权综合评价法构建班组安全行为风险的评价模型,在以年龄、职称及学历为控制变量的情况下,通过运用有序聚类的最优分割算法界定班组安全行为风险的阈值,阈值界定过程中以班组安全行为绩效为参照序列。结果表明,空中交通管制班组安全行为风险与职称及年龄变量相关性较高,其告警阈值的划分也相对更为严格,职称及年龄组告警区间明显窄于学历控制组的阈值区间,因而在充分考虑各控制变量的基础上划设空中交通管制班组安全行为风险的阈值将更为合理,可有效避免因阈值划设过松或过严而出现的漏警及虚警的问题。
According to the types of the team safety behavior risks in air traffic control （ ATC）, team behavior risk indexes are selected through practical investigation. Then, analytic hierarchy process （AHP） is used to build an index system. A comprehensive evaluation model is developed by weighting team safety behavior risks described by the risk destruction and resistance factors. In the model, it takes the age, professional level, and education as the control variables. By using the orderly clustering of optimal parti- tion algorithm, we take teamg performance as reference sequence to define the risk threshold value of the team safety behavior. Results show that the team~ safety risk behavior depends heavily on variable titles and ages in ATC. Its alarm threshold division is relatively stricter and obviously narrower than the part of diploma control. With full consideration of the total control variables by the proposed method, the risk threshold value is reasonable such that the threshold is neither too loose nor too strict, which can reduce both false positive and negative.
