中文摘要：

文中建立了基于复杂网络的供应链网络级联失效模型,通过对供应链网络突发事件的动态演变过程进行仿真,分析节点企业不同特性对供应链网络脆弱性的影响程度,识别出脆弱环节,给出供应链脆弱性的定量评估方法。使用仿真实例对该方法的应用进行了说明,并提出了相应的对策,可以在设计和运营策略上考虑级联失效特性的存在,有助于提高供应链网络的弹性和可靠性。

英文摘要：

In this paper,we establish the supply chain network cascading failure model which based on complex network,and simulate the dynamic evolution of the supply chain network triggered by unexpected events. We analysis of different characteristics of node enterprises on supply chain network vulnerability impact,identify the weak links and given a quantitative assessment method for the vulnerability. Using the simulation example to illustrate the method,we put forward some corresponding countermeasures. In the design and operation strategy,the existence of cascading failure characteristics is considered to improve the flexibility and reliability of supply chain network.
