A new index system of aerial warfare efficiency evaluation is proposed in this article, based on the characteristic of two great modes of modern aerial warfare within visual range and beyond visual range. In view of the weakness of single method in determination of weights in the traditional model, interval analytic hierarchy process (IAHP) is used to determine subjective weight and rough set method is used to determine objective weight. Then the subjective and objective weights are organically integrated, from which the optimal solution of interval combination weight is obtained. This method totally contains the advantages of the subjective weight evaluation method and the objective weight evaluation method, the use of it overcomes the weaknesses of the above evaluation methods and realizes the complementary advantages, which makes the result of efficiency evaluation more reasonable and scientific. Finally, the comprehensive evaluation model of aerial warfare efficiency is established. The feasibility and validity of the model are verified through the computation of an example.
