终端区空中交通管制运行品质涉及多个因素,单方面的改进会影响其他方面,需要经过综合评价才能形成有效的运行优化策略。为加强对终端区管制运行品质的综合评价,基于因子分析法对评价因子进行了研究。以成都终端区为例,根据专家调查法选取6项关键指标,采集繁忙时段10:00~22:00的有效样本共计57个,进行因子分析。结果表明:安全、流量、效率为评价终端区管制运行品质最重要的3个因子,权重依次为0.37、0.34、0.29。经在管制专家中开展模糊综合评价,证明因子分析结果与实际情况相符。所提出的研究结果,从定量分析角度为综合改善终端区管制运行品质提供了决策导向和检验依据。
The quality of terminal air traffic control operation involves a number of factors. Unilateral improvements will affect other aspects and require comprehensive evaluation to form an effective operation optimization strategy. In order to strengthen the comprehensive evaluation of the quality of terminal area operation, the evaluation factor was studied based on factor analysis. Taking the terminal area of Chengdu as an example, six key indicators were selected according to the expert investigation method, and 57 valid samples were collected during busy hours from 10:00 to 22:00 for factor analysis. The results show that safety, flow and efficiency are the three most important factors to evaluate the quality of terminal operation. The weights are 0.37, 0.34 and 0.29 respectively. After carrying out fuzzy comprehensive evaluation among regulatory experts, it proves that the factor analysis results are in accordance with the actual situation. The proposed research results provide a basis for decision-making and inspection for the purpose of comprehensively improving the operating quality of terminal areas from the perspective of quantitative analysis.
