摘要： 目标求精是场景和目标相结合的需求建模方法中的一个重要环节。该文基于目标和场景相结合的需求建模，提出了谓词驱动的目标求精方法，通过对目标谓词描述的分类来指导整个求精过程的进行。同传统的求精方法相比，该方法具有对需求分析员的依赖较小、自动化程度高等优点。

Abstract: Goal elaboration is an important step in requirement modeling method of combining goal with scenarios. This paper puts forward a predication-driven goal elaboration method based on such requirement modeling method. According to the classification of predication, it directs the elaborating process. Compared with traditional elaboration methods, the method is with less dependent on requirement analyzers and more automatic.
