Aiming at the problem of how to deal with the evaluation information scientifically in the evaluation of military aircraft overhaul efficiency, a method of military aircraft overhaul efficiency evaluation based on intuitionistic fuzzy method is proposed, and the corresponding index system is established. Based on the similarity between intuitionistic fuzzy numbers, the judgment matrix similarity is introduced to determine the expert weight;the intuitionistic fuzzy set weight aggregation operator is used to gather the expert weighting information to get the index weight;and the linear weighting method and intuitionistic fuzzy method are used to gather the overhaul efficiency evaluation information to get the evaluation values. The overhaul efficiency of a certain aircraft is evaluated, and the rationality and effectiveness of the method are verified, which provides a method support for further improving the efficiency of aircraft overhaul.
