Reliability of Air-Rail Hypernetwork under the Disturbance of Flight Delays based on Big Dada

In order to measure the reliability of air-rail network under the disturbance of flight delays, the air-rail network of China Eastern Airlines was taken as the research object. First, the air-rail hypernetwork model was established. the disturbance mechanism of flight delays on the air-rail hypernetwork under flight delays was analyzed. Then, the airrail network data of China Eastern Airlines were selected based on the big data. The global efficiency and the maximum relative size of connected subgraph were taken as the measurement indexes of reliability. And two groups of reliability of air-rail hypernetwork under different attack modes of flight delays were analyzed. The results shown that under the random attack mode of flight delays, the reliability of air-rail hypernetwork was stronger than that of the selective attack mode. When the proportion of airport nodes attacked was low, the reliability of air-rail hypernetwork under the selective attack mode was significantly lower than that of the random attack mode. However, when the proportion of airport nodes attacked reached a certain degree, the two groups of reliability of air-rail hypernetwork under different attack modes were gradually close to each other. No matter under the random attack mode or under the selective attack mode, the reliability of the air-rail hypernetwork was better than that of its airport network.
