Abstract: Accurately grasping the future war of joint operations, multi-area operations and intelligent operations, comprehensively deconstructing the urgent demand of the future war on the air battlefield, accurately locating the intelligent air combat command decisionmaking problem, seizing the technical dividend of the big model era, and increasing the uncertainty of the combat environment faced by the air combat command decision-making, based on the time challenge of increasing the autonomy ratio of command objects and insufficient knowledge reserve of command subjects, the four-level empowerment of big model is studied, including data acquisition, model training, combat process and autonomous decision-making in the process of intelligent air combat command decision-making. Finally, based on the rule decision-making, the purpose of real-time decision-making, the feedback of inference decision-making, the development proposal of building“big model + knowledge graph”,“big cloud model + edge computing”,“big model + wargame inference” models are proposed.
