摘　　要：采用Scenarios进行需求建模能够反映从用户角度观察到的系统的行为,状态图是系统行为的精确描述。从Scenario到状态图的自动转换是指软件开发过程中从UML需求模型自动生成行为模型的过程,其研究对于细化系统行为,保持开发过程中模型间的一致性有重要意义。对其研究现状及进展进行了介绍,并对现有算法进行了总结和分类,进一步指出这些算法的不足和今后需要改进的方向。Scenarlo-based requirements engineering reflects system behaviors in users＇ views, Scenarios are usually described by sequence diagrams. Statecharts are precise descriptions of system behaviors. Generating statecharts from scenarios is the process automated generating behaviors models form UML requirement models. This research is important for rapidly generating system prototypes and keeping consistency between models. The status quo of this research is presented in this paper. Existing methods is surveyed and classed. The shortcoming of these methods is further presented, Then the prospect of this research is given.
