Analysis on the Importance of Nodes in Supply Chain Network

Taking production, sale, etc. different links as nodes and the relations between such links as sides in supply chain network, then this supply chain network is a typical complex network. In this paper, the importance of nodes in supply chain network is discussed by using the theory and methods of complex network, the key nodes are identified with the help of software UCINET and MATLAB, moreover, obtained results are applied to the supply chain network of the automobile industry in Guangzhou to demonstrate its key nodes.
