Comparative evaluation of centrality criterion in a hierarchical network

The research of centrality in hierarchical networks is presented in the paper. The characteristics of graph centrality are analyzed and discussed. The basic centrality criteria are defined. The multi-objective assessment of graph nodes is proposed. The appropriate mathematical support and software have been developed within the framework of conducted research. The experimental research of the formulated criteria efficiency has been carried out as well. Keywords: centrality, hierarchical networks, characteristics of centrality, centrality criteria, multi-objective assessment.
