Study on resilience index of civil aviation airports under meteorological disasters
To study the performance of different airports'resilience under meteorological disasters and the causes of their differences,firstly,the definition of airport resilience based on airport functional level was put forward,which covered three sub characteristics:resistance,robustness and recovery.Then,by calculating the airport functional level under meteorological disasters through flight data,airport resilience index and sub characteristic indices were obtained to reflect the airport's resilience.Finally,taking the disaster of the snowstorm as an example,the distribution pattern of resilience index of affected airports in the United States and the reasons for the differences of resilience index among different airports were analyzed.Furthermore,the performance of the resilience index of the affected airports under the disaster of winter storms,floods,tropical storms and tornadoes was analyzed.The impact of disaster types on airport resilience index was also analyzed.The results indicate that the difference of airport resilience index is mainly caused by the resistance index.The key factors that cause the difference in airport resilience index under snowstorm disaster are throughput,aircraft fuselage maintenance plan level and engine maintenance level.The resilience index of the airport under winter storm,flood and snowstorm is basically the same.The lowest relative difference of the resilience index is 7.519%and 5.521%,while the average relative difference is 23.021%and 21.037%.The calculation method of airport resilience index proposed in this paper can accurately reflect the resilience properties of airports.
