空运网络演变中的反复出现

Recurrence in the evolution of air transport networks

Kashin Sugishita, Naoki Masuda

摘要:

随着时间的推移,航空运输网络的变化可能是由航空公司之间的竞争、航空业法规的变化以及恐怖袭击和流行病爆发等社会经济事件引起的。这种网络变化可能反映了每个运营商的公司战略。在本研究中,我们提出了一个框架,从递归的角度来分析离散时间的时间网络的演化模式。递归意味着网络结构返回到相对接近于过去的网络结构。我们将所提出的方法应用于1987年至2019年美国的四家主要运营商。我们发现,运营商是不同的自相关性,强度的周期性,以及这些数量的变化在几十年。我们还发现,个别运营商的网络结构会不时发生突然变化。这种网络变化反映了枢纽机场运营的变化,而不是与航空业密切相关的著名社会经济事件。所提出的方法预计将有助于揭示,例如,航空公司联盟的演变和应对自然灾害或传染病,以及随着时间的推移,社会,生物和其他网络的特征演变。

英文摘要:

Changes in air transport networks over time may be induced by competition among carriers, changes in regulations on airline industry, and socioeconomic events such as terrorist attacks and epidemic outbreaks. Such network changes may reflect corporate strategies of each carrier. In the present study, we propose a framework for analyzing evolution patterns in temporal networks in discrete time from the viewpoint of recurrence. Recurrence implies that the network structure returns to one relatively close to that in the past. We applied the proposed methods to four major carriers in the US from 1987 to 2019. We found that the carriers were different in terms of the autocorrelation, strength of periodicity, and changes in these quantities across decades. We also found that the network structure of the individual carriers abruptly changes from time to time. Such a network change reflects changes in their operation at their hub airports rather than famous socioeconomic events that look closely related to airline industry. The proposed methods are expected to be useful for revealing, for example, evolution of airline alliances and responses to natural disasters or infectious diseases, as well as characterizing evolution of social, biological, and other networks over time.
