基于复杂网络理论的供应链级联效应检测方法

Cascading Failure Model and Method of Supply Chain Based on Complex Network

针对供应链网络中的级联效应问题,建立了系统化检测的级联效应方法,提出了供应链网络中重要性节点的界定规则,并给出了动态的节点重要性评价方法.进而计算出最大连通子图规模,衡量了该节点失效对整个供应链造成的破坏性.仿真结果表明了该方法的有效性和实用性.

This paper focused on the cascading failure of supply chain network.A node importance evaluation method is employed to analyze the cascading failure characteristics.Then the critical nodes which may cause cascading failure in the whole network are identified.Finally,the damage degree of cascading failure measured by largest connected component is tested using the largest workload tolerance parameter.The simulation results indicate the validity and practicality of this method.
