When setting the weights of the indexes of threat assessment in air combat,the objectivity of threat assessment data can′t be fully reflected,and the subjective weighting method will affect the results of weight determination.To solve the problems,a weighting method combining the AHP method with the CRITIC method is proposed.The method uses the AHP method to synthesize the experts′ judgment of index weights first,and then determines the relationship between the objective data according to the CRITIC method,so as to realize the combination weighting of threat assessment indexes.Then,the VIKOR method is used to assess the threats in air combat through the simulation of an example.Finally,taking into account the subjective preferences of different decision makers,the method sets different attribute values of the VIKOR method to obtain different results of target threat assessment for comparative analysis.The simulation results show that this method has certain practical values.
