Risk Control of the Global Supply Chain

By use of a modeling approach of the complex network to construct a supply chain network model, this paper has mainly studied the problem of disruption risk control of the supply chain under the background of globalization. The simulation result of the supply chain network model showed that the supply chain network is scale-free. The key nodes in the supply chain network can be identified by calculating the centrality of the nodes. Detailed results demonstrated that the ability to resist disruption risks and the network resilience of a supply chain can be improved by adding redundancy of the supply chain network and keeping a high level of collaborative work with the key suppliers.
