基于模型的系统工程在航天器研制中的研究与实践

针对基于文档的传统航天器研制模式,存在着信息表示不准确、信息查找/更改困难等不足,指出基于模型的系统工程(MBSE)是解决这些问题的有效途径。根据MBSE的定义,分析其内涵;在继承国外实践成果的基础上,在航天器研制过程中进一步创新MBSE的理论,并应用MBSE理论指导航天器研制,以推动系统工程理论和实践的发展。

Research and Practice of Model-Based Systems Engineering in Spacecraft Development

In view of the traditional spacecraft development mode based on document and with the problem of information expression inaccurate and information search/alteration difficult, this pa- per presents that MBSE （Model-Based Systems Engineering） is an effective way to solve this problem. According to the definition of MBSE, its connotation is analyzed. On the basis of inher- iting overseas practice results, the concept of MBSE is extended in the practice of spacecraft de- velopment. And MBSE theory is applied to guide spacecraft development reversely. The develop- ment of the system engineering theory and practice is promoted.
