异质依存网络衰退特征与关键节点辨识
Degeneration Characters of Heterogeneous-interdependent Network and Key Node Identification
摘要
Abstract
In order to solve the problem that traditional com-plex network theory usually takes homogeneous single-layer net-work as research object, and neglects mutual coupling relations among heterogeneous nodes or multi-layer networks in indus-trial complex networks, the heterogeneous-interdependent net-work(HI net)theory with key node identification method is pro-posed. Taking the HI net with multi types of nodes as the object, we study the dependency relations of nodes and the mechanism of network degeneration. Then, the dependency matrix of het-erogeneous nodes is established to combine the multi-layer HI networks into one layer. To describe the effectiveness coupling for neighboring node under different fault mode, the effective-ness coupling coefficient is designed. Finally, the effectiveness coupling coefficient of neighborhood nodes and its propagation method are given to calculate the influence from node to net-works to identify the key nodes in HI net. The effectiveness of the key nodes identification method is verified by the simulations of two typical HI nets, including the power system with multi generations and power-information HI net.关键词
