摘要
“自由飞”是当今世界航空界研究的理想。机载飞行管理计算机系统对飞行航线的动态实时优化能力是实现该理想的一个关键。该文对这一优化问题进行了仿真研究 :首先讨论了针对该问题的仿真系统 ;然后针对普通寻优算法耗时颇巨的缺点 ,重点研究了基于一种改进的遗传算法的航线实时优化算法 ;最后给出了部分仿真实验结果以评估此算法的性能。
Free Flight' is the dream of current investigations on air traffic management. The ability of the onboard flight management computer system to optimize flight lines in real time is one of the key techniques to implement the goal. Simulation study is done to investigate the on-line real-time optimization of commercial aircrafts' flight paths in the paper: a simulation system is discussed first, and then a new optimization algorithm based on an advanced GA is presented because common algorithms are always too time-consuming. At last simulation tests are conducted to evaluate the new algorithm's performance.
