Abstract

Air transportation has always been of interest to national managers and planners due to its positive features, including high speed, safety, and large capacity. However, various constraints affect the efficiency of this system. In this research, the resilience of the air transportation network is examined. Constraints are divided into two categories: natural events and sabotage events. In this study, data from domestic flights in Iran were used to analyze the resilience of the air transportation network. For this purpose, the number of serviced flights was considered as an indicator of network performance, and the cascade failure diagram method was used to analyze resilience. The results show that in the most pessimistic scenario, with the removal of three airports, network performance drops below 10%, as indicated by the cascade failure diagram. Additionally, the ideal scenario of network performance decline was examined, and the results show that in this scenario, with the removal of 90% of airports, network performance remains above 45%. Based on the conducted analysis, the biggest problem in Iran's air network is the excessive concentration of flights in a few specific and high-demand airports, which greatly affects network resilience in case of any issues occurring for them.
