基于GIS的机场场面路径优化算法的研究

利用GIS技术，研究了进出港航班滑行路径的优化问题。为机场上刚降落和即将出港的航班规划最短滑行路径。判断航班在规划的滑行路径上是否会发生对头相遇。考虑到机场安全性和使用效率，要求保证进出港航班在滑行过程中按最短路径连续滑行，并且不能发生对头相遇。本提出了两种解决方法：(1)改变进港航班的滑行速度；(2)延迟出港航班的时间。通过实例验证了该算法的可行性。

ROUTE OPTIMIZING ALGORITHM OF AIRPORT SURFACE BASED ON GIS

The GIS technique is used for airport surface management to study the optimization of airplane taxiway for arrival and departure flights. The shortest paths are designed for just-arrived and ready-for-departing flights of the airport.Additionally, whether the flights could confront each other head-to-head on the taxiway is judged.In regard to the airport's security and efficiency, airplanes must continuously taxi along the shortest route and the head-to-head confrontation should not occur. Two schemes are designed: One is to change the taxiing velocity of arrival flights, the other is to delay the starting time of departure flights. This algorithm is approved by a practical example.
