Abstract:

Based on the characteristics of China’s space development model and the need for digitization, a data system covering the whole period, whole system and all elements of space engineering is constructed. The concept and composition of the space engineering multi-state holographic model are presented, and the digital definition of the complete product including the design information of total factors is realized. The whole lifecycle model system of space engineering is constructed, which systematically expresses the evolution process of the multi-state holographic model with time, system level and function level, as well as the coupling relationships among them. An integrated system of the polymorphic holographic model has been developed and applied in the typical space engineering models. The architecture-driven collaborative development model and data-driven product state management model are preliminarily formed to improve the design efficiency as well as effectiveness, and provide a reference for the applications of the complex system engineering in other fields.
