On the modern information battlefield, UAV have been widely used due to the advantages of no casualties and good maneuverability. However, during the UAV swarm combat, the UAV network will be interfered by the enemy, which will damage some key UAV nodes or communication links and affect the connectivity of the entire network, thus leading to the fact that the entire network becomes more vulnerable. Therefore, it is necessary to study the network vulnerability of UAV networks in interference scenarios. In this paper, a coupled map lattice (CML) model which is a dynamic system with discrete time, discrete space, and continuous state variables is proposed to assess the vulnerability of UAV networks. The CML model integrates multiple topological indicators such as node degree, node betweenness, and node clustering coefficient, and reflects the node state change of the UAV network in the interference scenario from the topological point of view. When changing the strategy of interfering UAV nodes in different interfering scenarios, the relative network efficiency and failure proportion are used as indicators to study the change of network vulnerability. The studies show that precisely interfering important UAV nodes in a network can cause more damage to the UAV network. We also discover that as the intensity of external interference increases, the entire network will become increasingly vulnerable and the vulnerability of the network will also have different manifestations under different interfering strategies.

“…Taking railway and airline systems in China as an example, Ouyang et al (2015) proposed a vectorbased approach to model the accessibility and vulnerability of the complementary transport system, where each system was modeled by a network and their interdependencies were described by interlinks. This vector-based approach has been applied to the accessibility assessment via the integrated bus and metro system in Wuhan (Hong et al, 2019) and the integrated metro and high-speed rail system in China (Hong et al, 2020), and the accessibility improvement optimization via the road-rail networks in Spain and Portugal (Perea et al, 2014;Repolho et al, 2013). Considering that the pure vector-based approach is incapable of estimating the accessibility of offnetwork areas (Nelson et al, 2019), some scholars used a cell-based method which divided the study area into regularly sized and spaced cells and integrated all travel modes (rail, road, walking) into a cell network to map accessibility to cities and critical services (Weiss et al, 2018(Weiss et al, , 2020.…”

A series of ambitious accessibility‐oriented policies have been launched in the world, which center around improving accessibility via the national multimodal transport systems including road, airline, and railway. The national multimodal transport accessibility assessment is one of the “basic” analyses for the design and implementation of these policies, whereas existing national‐scale accessibility studies either focus on single‐mode or two‐mode transport or ignore the schedule‐dependent nature of railway and airline. This article models the integrated road, railway, airline, and walking transport as a four‐layer network with the consideration of their interdependencies. An algorithm is then developed to accurately assess the travel time‐based accessibility on the four‐layer network with the consideration of the daily schedule of trains and flights. The proposed approach is applied to map accessibility to 363 cities in mainland China and analyze the optimal travel modes. In addition, this article investigates the travel time‐based vulnerability of the national multimodal transport system in mainland China under the extreme storm recently occurred in Zhengzhou (July 2021). The findings in this work provide insightful suggestions for transport planners to design the national multimodal transport systems and for stakeholders to schedule travels.
