摘要
通过对比研究结构化和基于场景的建模方法,分析、总结了具有代表性的需求建模方法IDEF0和使用实例图UCM(Usecase maps)的优缺点。在综合上述两种方法优点的基础上,提出一种集成需求分析建模方法的设计思想、实施步骤。最后给出了运用此方法对自动取款机(ATM)进行需求分析的实例。
By comparing structured and scenario-based modelling methods, the representative modelling methods for requirements analysis, IEDFO and UCM,are analyzed and summarized. Based on the integration of advantages and disadvantages of these two methods, the design thought and implementation steps of an integrated requirements analysis modelling method are proposed. At last, an example of using this method in analyzing the requirements of Automatic Teller Machine is given.
