Abstract: Facing the distributed and intelligent warfare, around the system construction based on software definition, it is proposed that system resources with decoupled capabilities are the basic components of the command and control（C2） system. Focusing on the efficiency generation of the C2 system, the conceptual principles of the system architecture paradigm are established to characterize the system architecture characteristics. For networked systems and intelligent systems, the system architecture paradigms are established respectively, including 7 types of resource operation modes and 6 types of resource relationship modes. Based on the intelligent system architecture paradigm, the intelligent system architecture design method is verified by the typical case for the guidance role for the establishment of the agile and adaptable command and control system. Finally, the typical case is used to verify the guiding role of the intelligent system architecture design method in the construction of agile adaptive C2 system.
