The Supply Chain Network Modeling Based On Complex Network And Its Robutness Analysis

In this paper, through analyzing the shortage of traditional supply chain network we put forward a modeling method based on complex network. In the basic model selection, we choose the local-world evolving model which is more applicable to the supply chain modeling and taking into account the nature of the supply chain network nodes in different characteristics. We proposed network local area selection mechanism based on node nature and distincted the number of nodes on the different nature and the number of edges.Through the expression of the degree distribution, cluster coefficient and the average path length we find that this network model characteristics like scale-free an small-world. After the establishment of the complex network model of the supply chain, we analyzed robustness of the model using the improved complex network efficiency and the number of betweeness and put forward some advices to improve the supply chain robustness based on the analysis.
