基于DoDAF的载人登月体系结构建模

Architecture modeling for manned lunar landing based on DoDAF

针对传统文本模式存在的需求域与设计域之间信息离散、关联性差、不易追溯等问题,采用基于模型的系统工程(model-based systems engineering,MBSE)方法开展载人登月系统设计。引入美国国防部架构框架(Department of Defense Architecture Framework,DoDAF),提出载人登月总体设计体系结构可执行模型的流程和方法;采用系统建模语言(system modeling language,SysML)建立了视图模型,描述了系统架构、需求模型和逻辑接口。并开展了初步逻辑仿真验证,可为载人登月系统设计和MBSE方法应用提供参考。

Aiming at the problems of information dispersion,poor correlation,and difficulty in traceability between the requirements domain and the design domain existing in traditional text modes,a model-based systems engineering(MBSE)approach is adopted to design a manned lunar landing system.The Department of Defense Architecture Framework(DoDAF)of the United States is introduced,and the process and method for the executable model of the overall design architecture of manned lunar landing is proposed.The view model is established using the system modeling language(SysML),which describes the system architecture,requirements model,and logical interfaces.A preliminary logic simulation verification is conducted,which can provide a reference for the design of manned lunar landing systems and the application of MBSE methods.
