摘要

针对网络系统中关键节点确认问题，提出了一种基于健康度的节点重要度评估方法。首先，分析系统健康度定义，然后根据网络节点间的连接关系，建立邻接矩阵，计算节点在正常情况和故障降级情况下的网络容量变化，建立系统健康度和节点重要度的关系模型。最后，将该方法应用于一个运输网络系统。仿真案例表明，该方法能够有效确定系统中的关键节点，有助于提高系统可靠性。

Abstract

For the identification of key nodes in network systems

a node importance assessment method based on the system health state was proposed.Firstly

the definition of the system health degree was analyzed.Then

according to the connection relationship between network nodes

the adjacency matrix was established to calculate the network capacity change under normal conditions and fault degradation conditons.And the relationship model between the system health degree and the node importance degree was established.Finally

simulations of network systems showed that this method could effectively identify the key nodes in the system and improve the reliability of the network.
