Study on invulnerability of emergency logistics network based on complex network
基于复杂网络的应急物流网络抗毁性研究*

Aiming at the research of the invulnerability of emergency logistics network,this paper measured the network invulnerability quantitatively by the average inverse geodesic length and the size of the largest connected subgraph.It analyzed invulnerabilities of the emergency logistics network including single-point distribution center in deference attack strategies.For each case of attacks on vertices and edges,it used different attacking strategies:removals by the descending order of the degree and the betweenness centrality.It shows that random attacks are often less harmful than select attacks and the invulnerability is weak based on removals by recalculated degrees when more vertices are attacked.
