Abstract In order to study the reliability of air-rail network under the disturbance of flight delays. The air-rail weighted hypernetwork model is constructed in this paper, and the disturbance mechanism of flight delays to the air-rail hypernetwork is analyzed. The reliability of China Eastern Airlines’ air-rail hypernetwork under occasional delay scenario and multiple-delay scenario is simulated and analyzed respectively. The results show that: In the case of occasional delay scenario, the reliability of the air-rail hypernetwork is strong, and the failure of a single airport node has only a limited impact on the efficiency of air-rail hypernetwork, and the impact on the network connectivity is minimal. In the case of multiple-delay scenario, the reliability of the China Eastern Airlines air-rail hynetwork is strong under the random disturbance attack mode, but weak under the selective disturbance attack mode. No matter it is under occasional delay scenario or multiple-delay scenario, no matter under the random disturbance attack mode or the selective disturbance attack mode, the reliability of China Eastern Airlines air-rail hypernetwork is superior to its airport network. Measures such as increasing the number of cities, strengthening the protection of hub nodes and strengthening information sharing are conducive to ensuring the reliable operation of air and rail intermodal transport network.
