摘要
Abstract
The development of systems engineering is summarized,and the shortcomings of text-based systems engineering(TBSE)are identified,such as unclear causal relationships,low com-munication efficiency between levels,susceptibility to deviations,and difficulties in maintaining and synchronizing relationships.The potential advantages of model-based systems engineering(MBSE)are also highlighted,including explicit causal relationships,high communication effi-ciency,high accuracy,and ease of maintaining and synchronizing relationships.The characteris-tics of spacecraft development are summarized and an in-depth analysis of potential misunder-standings and pitfalls when applying MBSE methods is provided,including role and function of MBSE,the relationships between MBSE methods and the development process and systems engi-neering process,and the relationship between logical and physical architectures in product mo-dels.Furthermore,some specific challenges encountered during the transformation process to-wards MBSE at the technical,tool,and organizational levels are addressed,and solutions are proposed such as strengthening foundational research,leveraging the advantages of various tools,and establishing comprehensive technical teams.These insights and recommendations can be pro-vided as references for spacecraft designers.关键词
