摘　　要：ConcurTaskTrees是一种具有代表性且广泛应用的图形化任务建模方法,它是用户界面设计的重要组成部分。UML2.0建模语言缺少对交互式用户界面设计的支持,将ConcurTaskTrees引入到UML2.0中能极大地提高软件设计的质量,但是目前还没有一致的和最好的方法实现这一目标。文章使用基于元模型的扩展机制,通过扩展UML2.0活动图,建立了ConcurTaskTrees的元模型及其表示法,避免了在移植过程中丢失ConcurTaskTrees的任务分类特性,从而将ConcurTaskTrees完整地、准确地引入UML中。ConcurTaskTrees is a typical and widely used graphical method for task modeling, and it is an important component of user interface design. UML2.0 lacks support for designing interactive user interface, thus introducing ConcurTaskTrees into UML2.0 will greatly improve the quality of software design, but at present there is still no the consistent and best approach to achieve this goal. The extension mechanism based on meta-model is used to build the meta-model and notations for ConcurTaskTrees by extending activity diagram in UML2.0, which avoids losing the task classification property of ConcurTaskTrees in transplanting process, so as to integrate ConcurTaskTrees completely and accurately into UML.
