Abstract: In order to solve the problems of complexity and uncertainty in the evaluation process of air combat
decision-making，an evaluation index set for air combat decision-making is constructed and a closed-loop
evaluation method based on cloud centroid method and consistency weighting is proposed． Firstly，the basic data
are normalized，and the corresponding air combat decision cloud model is established． Then，according to the
similarity and consistency of the indicators，the weight of the indicator set is constructed． Finally，the
appropriate threshold is selected to judge the validity of the evaluation and complete the closed-loop feedback of
the evaluation scheme． The simulation example shows that the scheme ensures the accuracy and validity of the
evaluation，avoids the stochastic problem of traditional methods，and truly reflects the decision-making quality in
air combat．

Key words: air combat decision-making, index set, clustering method, closed loop
