Abstract:

Model-based systems engineering (MBSE), which is able to improve the overall design ability and efficiency for the complex systems, has been widely employed in engineering domain. However, the application of MBSE in manned space engineering is still in its infancy. To regulate model-based requirements analysis and systems design during the project verification and design phase in manned space mission, the preliminary working methods and procedures for mission requirements analysis are proposed. Based on the methodology of MBSE and the characteristics of manned space engineering, the analysis process is proposed, including requirements analysis in mission level, requirements analysis in ability level, systems architecture design, requirements analysis in system level, simulation and validation, and requirements release. Finally, the U.S. Artemis project is utilized as the case study to show the detail analysis procedures. The proposed method lays the foundation for developing full-cycle digital design and technical management process for manned space engineering.

Key words: manned space engineering, model-based systems engineering (MBSE), requirements analysis, systems design, digitization
