门到门准时一直是航空运输业的运营目标。在本文中，提出了一个分析模型来模拟飞机在机场周转业务的效率。不同的飞机准点性能的情况下进行了模拟和测试。在模型中引入了将缓冲时间安排到飞机周转操作的地面时间中的概念，以降低飞机生产率为代价，以最小化操作不确定性引起的系统成本。为了考虑航班时刻表运行过程中的准点性不确定性，采用随机函数模拟进港航班的准点性。来自欧洲航空公司的飞行数据被用来验证模型。分析表明，在飞机周转时间中适当使用计划缓冲时间可以通过平衡计划准时性和飞机利用率之间的权衡来最小化系统成本。
Gate‐to‐gate punctuality has long been the operational goal of the air transport industry. In this paper, an analytical model is proposed to simulate the efficiency of aircraft turnaround operations at airports. Scenarios for different aircraft punctuality performance have been modelled and tested. The concept of scheduling buffer time into the ground time of aircraft turnaround operations is introduced in the model at the expense of reducing aircraft productivity to minimize system costs from operational uncertainties. Stochastic functions are employed to simulate the inbound punctuality of arrival aircraft in order to take into account the punctuality uncertainties from the operation of flight schedules. Flight data from a European carrier is used to validate the model. Analyses show that the proper use of schedule buffer time in aircraft turnaround time can minimize system costs by balancing trade‐offs between schedule punctuality and aircraft utilization.
