摘要： 指出了已有非功能需求描述方法的缺陷,提出了一种使用UML扩展机制描述非功能需求的新方法——NFRProfile,使非功能需求的描述更加直观和准确。同时,NFRProfile将UML从功能建模扩展到非功能建模,丰富了UML的应用范围,使得对功能和非功能的建模可以统一在同一种建模语言和同一个建模工具中。

Abstract: This paper points out the deficiency of the existing methods for specifying non-functional requirements(NFR), and proposes a novelmethod, NFR profile, to represent NFR by using UML’s extension mechanism, which makes NFR specification more intuitive and accurate.Meanwhile, NFR profile extends the UML from functional modeling to non-functional modeling, enriches the application of UML and makes itpossible to unify functional and non-functional modeling in the same kind of language and tool.
