The evaluation methods of node importance in Complex supply chain network

摘要

Failure of supply is typical phenomenon of cascading effect in complex supply chain network, in order to ensure the safe operation of supply chain network we should strengthen the management and protection important nodes. Based on this, the paper has proposed a evaluation methods of node importance to measure the size of the largest connected sub-graph node failure caused devastating consequences in complex supply chain network, and by example to verify the effectiveness and practicality of the evaluation methods.
