基于免疫克隆选择算法的繁忙时刻场面航空器调度优化(英文)

为减少大型枢纽机场拥堵和航空器地面等待,以总调度时间最小为目标,提出了航空器地面滑行调度模型并应用于首都机场航班调度。模型参考经典的车间调度思想,将滑行过程中的3类特殊的场面冲突作为约束条件。针对模型NP难解的特征,设计了免疫克隆选择优化算法求解模型。通过北京国际机场仿真实验表明,相比先到先服务(First-come-first-served,FCFS)策略,本模型将一个高峰时段的航班调度时间减少了13.6min,平均每架航空器的总滑行调度时间减少45.3s,提高了跑道容量和机场运行效率。

OPTIMIZATION OF AIRPORT TAXIING PLANNING DURING CONGESTED HOURS BASED ON IMMUNE CLONAL SELECTION ALGORITHM

In order to ease congestion and ground delays in major hub airports, an aircraft taxiing scheduling optimization model is proposed with schedule time as the object function. In the new model, the idea of a classical job shop-schedule problem is adopted and three types of special aircraft-taxi conflicts are considered in the constraints. To solve such nondeterministic polynomial time-complex problems, the immune clonal selection algorithm(ICSA) is introduced. The simulation results in a congested hour of Beijing Capital International Airport show that, compared with the first-come-first-served(FCFS) strategy, the optimization-planning strategy reduces the total scheduling time by 13.6 min and the taxiing time per aircraft by 45.3 s, which improves the capacity of the runway and the efficiency of airport operations.
