Air cluster threat assessment method based on battlefield situation variable weight

The invention provides an air cluster threat assessment method based on battlefield situation variable weight. The method comprises the following steps: establishing an air cluster threat assessment index system; constructing a quantitative model of the evaluation indexes; determining subjective weights of the evaluation indexes based on an analytic hierarchy process; determining an objective weight based on an entropy weight method; determining a constant weight based on the game combination; determining the variable weight of the index; positive and negative ideal points of the threat membership matrix are determined; calculating a perception utility value; determining positive and negative ideal solutions of the perception utility matrix; calculating a correlation coefficient with positive and negative ideal solutions; calculating a weighted grey correlation degree with the positive and negative ideal solutions; calculating a weighted Euclidean distance with the positive and negative ideal solutions; and e
