【摘要】 尽管各类场景元模型在需求工程中起到了很大作用,但各视点间的元模型缺少统一,为了解决此问题,提出了适用于多视点的统一场景元模型。其中,典型的场景元模型包括:面向行为和交互、面向目标和面向方面的场景元模型。每种视点类型的场景元模型都有各自的元素含义和元素关系,现从一个综合、适用于多视点的角度出发建立统一的场景元模型,确定其元素定义和元素关系,最终绘制出元模型的结构图,并检验能否适用于不同视点下的场景元模型。更多还原

【Abstract】 Despite their important role in requirement engineering,scenarios meta model suffer from several major drawbacks.To remedy these drawbacks,a unified meta model which apply to the multiple viewpoints is presented.There are three kinds of scenarios meta model:behavior and interaction oriented scenario meta model,target oriented scenario meta model and aspect oriented scenario meta model.Each of them has their own elements and relationship between elements.A new scenario meta model on a united and multi-perspective viewpoint is proposed and then a detailed description,illustration and assessment of this meta model is given.更多还原
