As a type of complex network, there exists many disadvantages in identification method of the key node in industrial control network, such as insensitive to the network size, unable to obtain the nodes weights and so on. In this paper we optimized the degree and betweenness, proposed the degree index and betweenness index, and got the weights of the nodes in the networks by these two synthesized indexes. Finally, through the ranking of nodes weights, digging out one or more the most important nodes, which are the key nodes of the network. The metho d can quantify the important extent of nodes and avoid sidedness of single evaluation method. Experiments showed that the method is feasible and efficient, computing ability get well improved.
