A quantitative method of vulnerability assessment was put forward on the foundation of research on current assessment methods home and abroad in order to evaluate vulnerability risk objectively.Vulnerability connection network（VCN） was discussed firstly for the purpose of taking connection of vulnerability into account,which divides vulnerabil-ity risk into entity risk and path risk;Secondly,advanced methods of quantifying entity importance in entity risk and network node connection effects in path risk were proposed;Lastly,an evaluation example of vulnerability risk on dis-patching management information system in power system was given out.Corresponding results show that quantitative assessment model brings out scientific and credible evaluation on vulnerability risk.
