A Kind of Structural Differential Point of S-Graph Based on Betweenness Centrality

摘要

Using S-Graph(SG) to model the complex system,the complexity of system results in the complexity of SG, but it dose not change. So, we look for a new method to find its main places and edges. Based on betweenness centrality of place that are used to grasp the main structure of the complex SG (the main places), the Structural Differential Point of SG based on Betweenness Centrality (SDPSG-BC) is developed, according to some rules, a new net system with the main places that betweenness centrality of places are greater than else places is constructed.
