Based on the Activity-Based Methodology(ABM),an architecture design method is proposed to solve the problems of design irregularity and data inconsistency.The architecture framework and development ideas are introduced,and three classic architecture design methods are analyzed:Structural Analysis and Design Technique (SADT),Object-Oriented Design Method (OODM) and ABM.The advantages and disadvantages of various methods are given.According to ABM,the architecture design method based on core architecture data is proposed,and the development process of the method is illustrated in detail.The development method based on core architecture data is used to establish the architecture model from the operational viewpoint for the future cooperative anti-submarine warfare mission conducted by underwater unmanned vehicle.According to the established model,the method has good operability.
