Dynamic behavioral evaluation is a hot research topic. In this paper, we take pilot behavioral evaluation for example, and propose a dynamic behavioral evaluation method based on “air-combat average time” + “dominant situation” + “air-combat credibility”. The features of this method are:1)the reasoning from “maneuver” to “maneuver” is introduced, viz., according to the current maneuvers, derive the next maneuver;2)multi-thread simulation is used, viz., each pilot is simulated by a thread, and each thread can conduct flight decision, flight dynamics solution and tactical maneuver, independently;3)weighting air-combat credibility computation formula, viz., in computing the air-combat credibility, the times of “dominant situation” and “equal situation” of each part and their weights are considered. The whole evaluation method is easy to implement; the efficiency of the algorithm is high; and the practicability of the project is strong. The experimental results show the dynamic behavioral evaluation method proposed in this paper is novel and effective.
