面向软件行为和多视点的需求建模方法

摘要

提出一种面向软件行为和多视点的需求建模方法,包括建模步骤和建模语言.其中目标系统根据问题域以及视点源被划分成视点.视点在需求模型中以实体的方式存在,每个视点通过从需求规格说明中提取的场景来描述,作为需求模型基本组成单位的场景模型则通过基本的行为复合而成.分析了基于行为和多视点的需求建模过程,讨论了需求建模语言:行为描述语言的语法和语义,并给出相关实例分析以及所实现的建模工具简介.%We proposed a software behavior and mulit view-point approach for requirements modeling, which includes modeling process and modeling language called behavior descriptive language(BDL). The system is divided into viewpoints based on domain and view focues. A view point is an entity in the final requirement model. Each viewpoint is constructed by scenarios elited from requirement documents, and scenarios are described by basic behaviors. We discussed about modeling process and the syntax of BDL as well as its semantics. We also give a case study and a brief introduction of modeling tool that we implemented for our approach.
