Abstract: The autonomy and intelligence of UAV swarm （UAVs）cooperative operation is an important trend in the development of future military command and control technology. To meet the increasing attention of demand for the application of UAV swarm, the concept and system of UAV swarm autonomous decision-making technology for cooperative operation tasks are proposed in this paper, and the Communication, Decision, Planning, Control （CDPC）autonomous decision-making framework for multi-task of UAV swarm is established.Centralized, fully distributed and hybrid decision-making styles are established according to the communication topology, on the basis perceptual task inference decision-making models and rational task inference decision-making models are established respectively, and the solution framework of the models, as well as the key technical solutions are explored, indicating that UAV swarm task decision-making methods has better guidence meaning for the planning and implementation of cooperative operations.
