SysML:一种新的系统建模语言

SysML（Systems Modeling Language）是国外正在研究的一种新的系统建模语言，是为系统工程应用开发的标准建模语言，它的内容包括SysML语义和SysML表示法两个部分。介绍了SysML的产生背景、元模型理论、语言体系结构和语言形式，重点介绍了SysML的九种基本图形：类图、装配图、用例图、需求图、参数图、顺序图、活动图、状态机图和时间图，总结了SysML的主要特点和应用领域。

SysML: A New Systems Modeling Language

SysML is a new kind of systems modeling language being studied abroad. It is a standard modeling language for systems engineering application, which includes SysML semantics and SysML representation. The background, metamodel theory, language architecture and formalism of SysMLwere introduced. More attention was paid to nine basic diagrams of SysML which are class diagram, assembly diagram, use case diagram, requirement diagram, parametric diagram, sequence diagram, activity diagram, state machine diagram and timing diagram. Finally, main characteristics and application scope of SysML were summarized.
