Slot misuse phenomena in capacity-constrained airports with seasonal demand: the Greek experience

Abstract

Airport slot misuse disturbs the efficient and continuous operation of capacity-constrained airports, leading to congestion and delay problems. Deviations from the coordinated schedule in regional airport systems that feature seasonal demand and delays in certain peak periods are studied in this article. The Greek airport system is considered as a case study. Deviations are quantified by computing the difference between scheduled and actual aircraft arrival times as well as the hourly slot capacity utilization ratio. Two collective indicators for airport benchmarking are proposed. An in-depth analysis of slot allocation deviations and the delays they cause is carried out for a representative sample of airports that are classified according to the proposed indicators. A brief discussion on potential measures to mitigate slot misuse is also presented.

多跑道降落飞机协同调度优化

为了制定安全、高效的空中交通管理战术决策,研究了多跑道降落航班协同调度问题.基于协同决策理念,综合考虑空管、航空公司和机场等因素,提出一种协同航班调度策略,给出了协同调度优化模型.模型在满足安全性和公平性约束条件下,寻求总延误成本最小即功效性最大的调度方案.采用基尼系数建立公平性约束,以处理功效性和公平性之间的关系,并引入当量航班概念来定量分析公平性.针对多跑道航班调度问题的特点,设计了遗传算法予以求解验证.仿真结果表明:该算法总延误成本比先到先服务算法降低了72.6%,最大延误时间减小了50.8%,因此,调度的功效性与公平性得到提高,所提方法有效.     

Discussion on the dispersion ＆ agglomeration of aircraft industry

The aircraft industry is crucial to the economy and security of a nation. In this paper, the spatial characteristics and patterns of the aircraft industry are analyzed on different spatial scales. It is found that there is a 'Matthew effect' in the global aircraft industry and the spatial evolution of the industry is consistent with the industrialization process of the whole country. It is also revealed that the spatial evolution of the country is driven by both the centripetal forces including capital, talents, technology and agglomeration economies and the centrifugal forces including the comparative advantage, cost &risk sharing, emerging markets, development policy for less-developed regions and the military imperative. These forces have both market-stabilizing and market-disrupting effects on the spatial evolution of the aircraft industry. The study suggests that lessons drawn from the experiences in the United States and France are expected to be conducive to the rise of China's aircraft industry in the future.
