Asymmetric response model for evaluating airline service quality: An empirical study in cross-strait direct flights

In this paper we propose a framework to investigate service quality asymmetrically. An asymmetric response model within structural equation framework is developed to study the relationship between service quality and the passenger’s behavioral intention in the cross-strait direct flight (Taiwan–Shanghai). The results reveal that service quality in the loss region has more impact on behavioral intention than service quality in the gain region. Hence, attention should be paid to the service quality of important attributes in the loss region and strategies should ensure service quality of those important attributes that meet passenger’s expectations.     

MAS在机场路面路径优化中的应用研究

利用多Agent技术,研究进出港航班滑行路径的优化问题,为刚降落和即将出港的航班规划最短滑行路径,判断航班在规划的滑行路径上是否会发生对头相遇.由于多Agent技术更能体现人类的社会智能,更适合开放的、动态的社会环境,因此引进这一技术对进出航班滑行路径进行优化.文中将每架飞机被看作是一个Agent;将跑道,滑行道,停机位等看作是资源Agent;在多Agent环境下,优化出最佳的滑行路径.

我国航班时刻资源的分布研究

采用中国民航局发布的航班计划数据,分别从航空公司、机场、地区空管局三个角度统计分析我国航班时刻资源的分布情况。通过计算航空公司在各个时间段的起飞降落班次情况、各个机场的计划航班和最大容量差距情况和七大空管局在各时段的航班情况,得到南方航空公司占有的航班时刻资源最多,北京首都机场的航班时刻资源最为紧张,华东、中南、华北区域是我国最繁忙的区域的结果。作者还进一步从航班时刻的角度分析了影响航班准点率,造成航班延误的因素,并给出了相关的对策建议。     

Airline flight scheduling for oligopolistic competition with direct flights and a point to point network

In this research, we consider a flight scheduling problem for oligopolistic competition with direct flights and a point to point network. In this type of market situation, passengers are sensitive to the departure time of a flight rather than the transfer time. The airline needs to carefully consider the departure times of their competitors when determining their own. Therefore, unlike past approaches which have only considered one departure time for a competitor's flight, a flight scheduling framework is developed which takes into consideration possible competitor departure times. The framework includes two dependent stages which are repeatedly solved during the solution process. In addition, an upper bound model is also designed to evaluate the solution quality. Numerical tests are performed using data for Taiwan's outlying island route which is characterized by the above market situation. Satisfactory results are obtained, showing the good performance of the framework. Copyright © 2017 John Wiley & Sons, Ltd.

从复杂网络角度对2001—2010年我国航班流网络结构进行实证分析.通过计算网络结构的统计指标,验证了该网络具有小世界特性和无标度特性,并构建了最大连通子图尺寸下降率和整体效能下降率指标,对其进行抗毁性分析.根据不同年度对比分析,发现我国航班流网络抗毁性有逐年提高的趋势,但却更依赖于几个关键机场.通过各种攻击方式的对比分析,得出我国航班流网络对随机攻击表现出较强的鲁棒性,而对恶意攻击却非常脆弱.整个网络的可靠性主要由少数重要机场决定,需要重点确保这类机场安全高效运行,并向多枢纽系统发展.     

基于多Agent的机场场面最优滑行路径算法

为了保障机场安全,提高机场运行效率,建立了依据进出港航班滑行时间最短为决策的多Agent模型,模型以多Agent技术为基础,融合了Dijkstra算法的最优路径选择和合同网协议的思想,形成了基于多Agent的滑行路径优化算法,并依据该算法进行了仿真分析.仿真结果表明:与指定航班优先级相比,使用基于多Agent的优化算法处理同优先级航班,总运行时间可减少15 s;基于多Agent的场面运行调整算法可以有效地把航班和机场上分布的滑行道、跑道、停机位等资源组织起来,智能地发现冲突、躲避冲突,达到全局滑行时间最短,因此,该算法可行.
