A method and system for seepage analysis of interdependent networks based on edge coupling

Abstract

The invention belongs to the technical field of complex network seepage phase transition behavior analysis, and discloses an edge-coupling-based dependent network seepage analysis method and analysis system. The edge-coupling-based dependent network seepage analysis method includes: constructing an edge-edge-dependent network model; using The self-balancing probability theory establishes the theoretical analysis framework of the edge-edge dependent network model; based on the constructed theoretical analysis framework, the seepage phase transition behavior and seepage threshold of other edge-edge dependent network models in the face of random failures are analyzed. The invention adopts the self-balancing probability theory to establish the theoretical analysis framework of the model, and can directly write out the state equation after the system is stabilized without tracking the cascading failure process, which has the advantage of being intuitive and concise. Based on the theoretical framework, the present invention analyzes the phase transition behavior and seepage threshold of the model in the face of random failure, and has reuse significance for understanding the robustness of edge coupling networks in the real world.

Description

technical field [0001] The invention belongs to the technical field of complex network seepage phase transition behavior analysis, in particular to an edge coupling-based dependent network seepage analysis method and analysis system. Background technique [0002] At present, with the advancement of society and science and technology, the scale of various networks in the world on which people live is getting larger and larger, and the connections between networks are getting closer, especially the interdependence between infrastructure networks. Very common, such as power-information network, the power station provides energy for the information network, and the information network provides control signals for the power grid. These interdependencies between networks greatly increase the vulnerability of the network. The Italian blackout in 2003 has inspired researchers to study the robustness of networks from the perspective of interdependence between networks. Scholars abs...

Problems solved by technology

[0006] Through the above analysis, the existing problems and defects of the existing technology are: the existing interdependence network modeling abstracts the interdependence of the network as the interdependency of the nodes and does not consider a kind of actual situation, that is, the edge of one network and the other network There is a dependency on the edge of
