As a critical foundation of air transportation, the airway network (AIN) plays an essential role in ensuring smooth flight operations. Analyzing and optimizing the structural characteristics of the AIN can help reduce flight delays and enhance the safety and reliability of air transport. In this paper, an order degree relative entropy (ODRE) model for the AIN is established based on information entropy theory. Simplified AIN models are constructed based on the actual Chinese AIN and its subnets in Beijing, Shanghai, and Guangzhou. Various attack strategies-random, degree, betweenness, closeness, eigenvector, and Bonacich centrality-are applied to the AINs. The ODRE is used to evaluate the comprehensive robustness of the AINs under these diverse attacks. Compared with traditional methods, the proposed ODRE in this paper significantly enhances the reliability and applicability of the system while maintaining consistency and stability in network efficiency. It enables a more precise assessment of AIN vulnerability under different attack scenarios and provides deeper insights into network structure and dynamics.

Entropy
When an ideal gas expands isothermally, the disorder in the gas increases. From the molecular perspective, the gas molecules have more volume to move around in.
Consider an infinitesimal step in the expansion, which...
Entropy and the Second Law of Thermodynamics
The relation between entropy and disorder can be illustrated with the example of the phase change of ice to water. In ice, the molecules are located at specific sites giving a solid state, whereas, in a liquid form, these molecules are much freer to move. The molecular arrangement has therefore become more randomized. Although the change in average...
