Topological structure modeling and analysis for cyber-physical systems

Topological analysis for Cyber-Physical Systems (CPS) is the foundational research of its system analysis. This study proposed a new CPS topological structure model: interactive networks model, according to CPS internal structural features. Then, inner degree distribution and interactive distribution of CPS were analyzed, which could reflect the node connective characteristics. Moreover, the node interactive betweenness was defined based on information interacting in CPS. It can measure the node importance. And the node importance ordering was determined by calculating interactive betweennesses of all nodes. The results can provide valuable guidance for deployment, running and maintenance of CPS.
