abstract="In order to accurately evaluate importance of nodes and links in the network system, three kinds of situations concerning anti-attack capability of network system were analyzed, and based on the definition of traditional betweenness, an improved definition of network node and link betweenness was proposed, which was the number of times that all OD pairs passed through a node or link to meet the given constraint condition. Then, a new RSA was proposed to solve the improved betweenness of nodes and links. Finally, the traditional and improved betweenness of each node and link in Beijing subway network were calculated to evaluate their importance, and calculation results of traditional and improved betweenness were compared. The results show that the improved betweenness is a universal definition, while the traditional one is only one of its special cases, and it can evaluate importance of nodes and links from a more comprehensive perspective. © 2022 China Safety Science Journal.
