Based on analyzing the characters of single hub and spokes network ,which is used in China airliners, and the principles and working flow of aircraft tail number assignment(TNA) problem, studying the mathematical models of aircraft TNA problem, this paper introduced a new concept called "flight pairing", put forward a new TNA model, which classified a specific TNA problem into one of three typical TNA modes, TNA based on fleet dispatching commands, TNA based on fleet balance application, TNA based on minimum...

Based on analyzing the characters of single hub and spokes network ,which is used in China airliners, and the principles and working flow of aircraft tail number assignment(TNA) problem, studying the mathematical models of aircraft TNA problem, this paper introduced a new concept called "flight pairing", put forward a new TNA model, which classified a specific TNA problem into one of three typical TNA modes, TNA based on fleet dispatching commands, TNA based on fleet balance application, TNA based on minimum fleet requirement. Applied results show that the error of TNA is only 4.8 min, the time of attaining TNA is only 23 s, which indicates the model is feasible. 2 tabs, 2 figs, 8 refs.

分析了国内航空公司普遍采用的单枢纽线性航线结构以及飞机排班工作流程和要求,研究了描述飞机排班问题的数学模型构造方法,引入"航班节"的概念,将一个具体的飞机排班问题归结为三种典型排班模式中的一种,即基于飞机调度指令要求的排班问题、基于最少需用飞机数的排班问题、基于飞机使用均衡要求的排班问题。应用结果表明平均每架飞机分配的航班任务时间与期望飞行时间的偏差仅为4 8min,而且得到飞机排班方案的时间不到23s,因此此飞机排班模式是解决单枢纽线性航线结构下的飞机排班问题的一种有效方法。

By using the adaptive genetic algorithm, authors solved the scheduling of arrival aircrafts landing on single runway. The method of encoding is constructing the sequence of aircrafts. In decoding phase, used the moving method to decide aircrafts landing time. Designed the fitness function which can reflect the early and tardy cost. The genetic operators adapted include expected value model, order crossover and inverse operator.Authors used the adaptive method to adjust the crossover and mutation rate in order to improve the efficiency and avoid premature.

基于自适应遗传算法,实现了单跑道降落飞机调度问题的求解.算法以所有飞机的排列次序做为个体编码,解码时用移动方法确定飞机的降落时间.适应度函数的构造综合考虑了飞机的提前和延迟带来的损失,选择算子采用期望值方法,交叉算子用顺序交叉,变异算子用倒位变异.为提高算法的执行效率并避免早熟收敛,对交叉和变异概率均采用自适应策略.仿真结果表明了自适应遗传算法用于飞机调度问题的有效性.

According to the airline delay caused by increasing air traffic, an approaching aircraft sequencing algorithm with fuzzy logic control is put forward. Input of fuzzy logic controller are main factors considered by air traffic controller, its output is relative sequence of landing aircrafts.
