Measurement of the integration level of supply chain based on complex network

The paper introduced the complex network theory into supply chain research, and set up the model of the integration level of supply chain. Firstly, the paper looked back related researches about complex network and measurement of integration level of supply chain. Secondly, the paper put forward features of supply chain network: directed graph; nodes increased randomly but asymmetrically; and preferential attachment of nodes in locality. Thirdly, on the foundation of analyzing impact factors of supply chain complex network integration, built up evaluation model according to the statistics property of complex network, finally executed example calculation and conclusion.
