The Directed Complex Network Application in the Supply Chain

Supply chain is a network composed by business entities with different function. This paper analysis the network statistic characteristics of model such as degree distribution, supply chain average shortest path and betweenness. The finally result shows that both in-degree and out-degree of the directed supply chain complex network node obey the power-law distribution and the directed supply chain complex network has a small supply chain average shortest effective path. And its clustering coefficient is a low average. Finally its betweenness centrality increases with the increase of the degree.
