Abstract: The rational setting of flight cut-off time plays a significant role in enhancing airport service efficiency and improving passengers aviation travel experience. Thereby, exploring its impact mechanism can provide a theoretical reference for airports to formulate and optimize flight cut-off time according to demand. Firstly, an influencing factor system for flight cut-off time was established, which was based on literature research and survey results that identified 15 primary influencing factors. Secondly, by combining Grey-DEMATEL-TAISM, the causality degree and centrality ranking of each influencing factor were calculated, and then two root cause key influencing factors, four sensitivity key influencing factors, and a set of key influencing factors with a mutual causal relationship were determined. The research findings indicate that passenger flow line design, departure resource allocation, flight ground support services, ground support equipment configuration, and collaborative operation levels are significant factors affecting flight cut-off time. Among these, the passenger flow line design is a strong driving factor that requires particular attention in operational management. Passenger throughput and terminal configuration, located at the bottom of the topology, serve as root influencing factors, which can be improved by methods such as reasonably predicting throughput during the early-planning stage and replacing large single-building terminals with one airport and multiple terminals. The classification of factors within the causal loop encompasses passenger flow, baggage flow and flight flow. It is essential to pay full attention to the containment relationships among these three systems and enhance airport operational efficiency through collaborative management.

摘要： 航班截载时间的合理设置对提升机场服务效率、提高旅客航空出行体验感等方面发挥着重要作用，探究其影响机制，可为机场按需制定及优化航班截载时间提供一定的理论参考依据。首先在文献研究和调研结果确定15个主要影响因素的基础上建立航班截载时间影响因素体系；其次，将Grey-DEMATEL-TAISM相结合，计算各影响因素原因度、中心度排序，进而确定2个根源性关键影响因素、4个敏感性关键影响因素和1组互为因果关系的关键影响因素。研究结果表明：旅客流线设计、离港资源配置、航班地面保障服务、地面保障设备配置、协同运行水平是影响航班截载时间的重要因素，其中旅客流线设计是强驱动型因素，运行管理中需重点关注；位于拓扑图底层的旅客吞吐量、航站楼构型是根源影响因素，可通过前期规划阶段合理预测吞吐量，采用一场多楼替代大型单体候机楼等方式改进；因果回路中的因素所属分类涵盖旅客流、行李流和航班流，需充分重视3个系统间的牵制关系，通过协同管理来提升机场的运行效率。
