A new important nodes identification method in multi-layer heterogeneous combat network with meta-path centrality

Journal of Complex Networks, Journal Year: 2024, Volume and Issue: 12(3)

Abstract Identifying important nodes is of great significance to improving the stability and security heterogeneous combat networks. Due heterogeneity diversity connections, networks usually are multi-layered. In order model network more accurately identify nodes, this paper proposes a new identification method in multi-layer (MHCN). This takes into account not only topological information between but also meta-paths formed by node interactions closeness their associations. Furthermore, it considers uncertainty command control (C2) structure within MHCN. Specifically, first, tensor representation MHCN proposed represent intra-layer inter-layer nodes. Then, meta-path its calculation capture interaction Next, degree centrality, combined importance C2 entropy MHCN, which can use characteristics measure MHCNs with different structures. Finally, experiments carried out on real case verify effectiveness practicality method. The results provide useful insights for operational guidance design structure.

To alleviate the tense situation of limited passenger service resources in terminal and to achieve matching resource scheduling with flight support process, process–resource interdependent network is constructed according its mapping relationship time-varying characteristics empirical evolution conditions are analyzed. Then, node capacity, load, cascading failure process investigated, impact average rate quality standard on queue length considered, capacity model under condition constraints, load-redistribution adaptive method based proposed. Finally, method’s effectiveness verified by analysis, efficiency assessed using total time variance, robustness proportion maximum connected subgraph. The results indicate that effective improving efficiency, value measurement smaller than allocation 0.069; terms improvement network, phenomenon re-failure after load redistribution significantly reduced.
