Evaluation of Air Transportation Network Resilience Using Adaptive Capacity

Enhancing network resilience has been an important research topic for several decades with the increasing failures of critical infrastructure by disasters or terrorist attack. For critical infrastructures, such as electricity grid, water supply, and transportation, reliability to provide a stable level of service is most required. This paper proposes a resilience evaluation methodology with application to air transportation system. It is one of the major worldwide transportation modes and known as one of representative scale-free networks, which is relatively robust against random failure but vulnerable to targeted attack on hubs. This paper evaluates the air transportation network resilience using proposed adaptive capacity concept. Suggested measurements quantify the adaptive capacity, by which the capability of a network is to replace the damaged node with other redundancy of the network. Consequently, this study will help to diagnose the network resilience and contribute to planning for improvement of network resilience.
