摘要
目前,航班飞行需求激增和恶劣天气已经严重影响到航空空域的正常运行,为此针对空域拥堵时航路的时隙航迹资源协同分配进行了研究。根据问题的数学描述,以总延误成本最低和公平损失偏差系数最低为两个目标,建立了航路资源协同分配模型,运用多目标遗传算法(NSGA-Ⅱ)对模型求解分析。通过航路网络的典型数据测试该模型,生成了可供决策者选择的帕累托最优解集,并与传统RBS算法进行比较,实现平均延误成本降低8.5%,平均公平损失偏差系数降低70.6%。结果证明NSGA-Ⅱ算法可以较好的解决航路资源协同分配的问题。
In airway network, the excess traffic demand and the influence of weather conditions have become the main reasons for airspace traffic congestion. This paper investigated the collaborative allocation of time slots and trajectories during airspace traffic congestion. According to the mathematical description of the problem, we proposed a collaborative allocation model with the minimum total delay cost and the minimum deviation coefficient of fair loss as two objectives. Then a non-dominated sorting genetic algorithm-Ⅱ(NSGA-Ⅱ)was applied to solve the problem. By testing the model with typical data of route network, a Pareto optimal solution set selected by decision makers was generated. Comparing the algorithm with the traditional RBS algorithm, the average delay cost was reduced by 8.5%, and the average fair loss deviation coefficient was reduced by 70.6%. The comparison shows that the NSGA-Ⅱ can be well applied in the research of slots-trajectories collaborative allocation.
