Research on Robustness and Repair of Water-Rail Intermodal Transport Network under Different Information Conditions

This paper takes the coal sea-railway transportation network as an example to study and simulate the network robustness and repair under different information conditions. First, based on the basic theory of complex networks, the network model is constructed and its topological properties are analysed. Secondly, by analysing the influencing factors of network robustness, different attack strategies and robustness assessment index systems are established. Then, considering the minimum risk of repair material distribution and the shortest distance, a repair material distribution path selection model and network repair process were established. Finally, by designing the network robustness attack strategy simulation algorithm under different information conditions, the robustness of the network is simulated, and the importance of node repair is ranked, and the repair material distribution route is obtained. Through the entire process simulation of network construction, network attacks, and network repair, network optimization measures are proposed to lay the foundation for network risk protection.
