In the development of traditional equipment, the requirements for the combat scene are incomplete, the lack of the guidance of the standardized method is not fully proposed. In order to solve the problem of the fuzzy and constrained mapping relationship between the requirements of the equipment, this paper, based on the American defense architecture framework, is based on the framework of the system, the acquisition and control of the island of the south of the island, and the operation system structure model, the operation elements and the operating strategies, and the demonstration and verification evaluation of the STK simulation. The results show that the design of the dodaf system is able to show the logic of the combat system, and the more clearly the requirements of the combat scenario, provide the decision reference for the requirements of the subsequent equipment.
