考虑大型机场拥塞问题日益严重,从航空公司的利益出发,采用推迟飞机起飞时间的方式,将成本较高的空中等待转化成地面等待。基于离散事件系统的地面等待模型就是针对此类问题而提出的。通过对模型求解进行研究,针对遗传算法的速度无法满足目前要求的问题,提出使用0.618算法完成求解过程,通过对计算过程进行改进保持了计算结果的准确性并且提高了速度。实验结果表明,0.618算法的结果与遗传算法相差2.5%,但在速度上提高11.9%,验证了此方法的有效性与实用性。
Considering the overloading and serious congestion of some large airports, according to airline's interest, certain delays are imposed on some aircrafts at take off in order to avoid more expensive air delay. This method can change the expensive air holding to ground delay. Ground - Holding Model based on discrete event is just proposed for solving this problem. After researching on model calculation, 0. 618 algorithm is proposed to finish model calculation, aiming at that the genetic algorithm can not meet the performance requirement, and some improvement are applied to keep accurate result and fast calculation. The experiment shows that the result of 0. 618 algorithm is different from genetic algorithm by 2.5%, but 0.618 algorithm is faster by 11.9% k, which has verified the effectiveness and practicability of the model and algorithm.
