中文摘要：

针对我国大型机场国内航线高峰时间运力不足导致航班时刻拥堵,及国际航线航班时刻少、竞争力较弱的情况,在满足客货运输需求的前提下,提出了航线机型优化模型以及航班时刻优化方法。在此基础上利用SIMMOD对优化结果进行模拟仿真。验证了航班优化的可行性和适用性,指出了航班优化对减少地面延误,提高放行正常率具有重要作用。

英文摘要：

Under the lack of flights peak time capacity has led to flight schedule congestion,less international flight schedule and less competitive in domestic large airports,amodel of changing the aircraft type and schedule optimization method were proposed based on the demand for passenger and freight.Through the airport simulation softwareSIMMODverify the feasibility and applicability of the method,and indicate the importance of flightoptimization method to reduce ground delays and improve the release of the normal rate in the busyairports.
