Aiming at the problem that it’s difficult to determine the enemy’s airborne area under information condition, after analyzing the airborne battle characteristic deeply, concluding the index system that contains the elements which have an influence on predicting the enemy’s airborne area. Then apply the intuition fuzzy reasoning and evidence theory to fuse the fuzzy and conflict group decision and make sure the most possible airborne area of the enemy. The result shows that the method can represent the fuzzy information more effectively and make the reasoning result more objective.
