In order to reduce the result inaccuracy caused by uncertain factors in capability evaluation of aircraft icing defense system,a quantitative evaluation method using uncertain language was proposed.Based on the introduction of interval number and language evaluation criterion,a method of translating language variable into interval number was proposed,besides uncertain language variables and the algorithms between them were defined.In addition,the index system of aircraft icing defense system was developed.In order to obtain interval number weights of each index in this system,interval number eigenvector method was employed,besides,IA operator and weight sum method on interval vector were also used to aggregate these indexes.Finally,a certain aircraft icing defense system was taken as an example to demonstrate this method,and the capability of this aircraft icing defense system was shown in interval number.
