复杂网络的节点重要性综合评价 (Synthesis Evaluation Method for Node Importance in Complex Networks)

In complex networks,how to rank the nodes according to their importance plays key roles in various kinds of fields.Against the problem that most of the existing single index are unilateralist and limited,and most of the current synthesis evaluation method is also inaccurate,we proposed a new synthesis evaluation method combining principal component analysis with TOPSIS.We used our method to analyse the ARPA and the USA airport network.The result suggests that our method should be effective and corrective,and also lays the foundation for further more evaluation of node importance.
