Abstract: Aiming at the problem of complexity and obvious vulnerability exist in the supply chain network structure under the modern production mode,a vulnerability analysis solution for supply chain network topology was proposed.The concept and related expression of supply chain vulnerability was cleared,and the supply chain vulnerability weighted analysis model was designed.With the condensation degree analysis based on nodes contraction method,physical structure important nodes in the supply chain network were determined through comparing condensation degree change between before and after the network contraction.The interaction relationship of network nodes was analyzed,the nodes contraction method of weighted network was improved and the problem of net supply chain vulnerability was quantitative analyzed through the network nodes condensation degree weighted.The feasibility and effectiveness of this method were verified by experimental analysis.
