Evaluation for target threat is an important part in the defensive decision making. As to each target, there are multiple attributes described by fuzzy or uncertain information which is represented with interval numbers. How to integrate these fuzzy information becomes a meaningful work. This paper integrates the fuzzy numbers by introducing the distance among interval numbers to find a special interval number whose distance is the optimal value from all other interval numbers, then the comparison between multi-attributive targets is transformed into the comparison among only several interval numbers. On this basis, this paper solves the question about how to make a sequence among the aerial targets according to their different threat degrees.
