In order to solve the problem of fuzziness and randomness in evaluation of hazardous materials transportation network node risk of coming under terrorist attack,a method based on cloud model was worked out.Firstly,from the view of terrorist,node identifiability,node approachability,node symbolic sensational effect and harm degree were regarded as node evaluation index set,and weight clouds of node evaluation indexes were determined by Delphi method;Secondly,the maximum and minimum evaluation values given by evaluators were combined by synthetical cloud,then evaluation cloud corresponding to node risk was determined by data-drive approach based on cloud transformation.Finally,the node risk was calculated by arithmetic rules of cloud.An example shows the validity and the feasibility of the method.
