【摘要】 以简化软件产品线中的需求分析过程、实现过程复用为目的,总结了当前软件生产线需求分析的特点以及分析过程,通过建立领域用户需求模型指导需求获取分析过程,采用基于改进原型法的需求获取方法,基于领域用户需求模型建立需求复用库,引入本体描述用户需求模型等方法,对软件产品线的需求分析过程进行了改进,并设计实现了一套图形化需求建模工具,有效地简化了需求分析过程,实现了过程复用。其研究结果应用到了D2G软件生产平台中。更多还原

【Abstract】 For simplifying the process of requirement analysis of software product lines and realizing software requirement process reuse,summarizes the characteristic and process of the requirement analysis of software product lines.Through building domain function requirement model,improving the method of requirement elicitation based on prototype,creating and managing the requirement reuse library and creating a type of model description language based on ontology,improves process of the requirement analysis of software product lines and designs and develops a visual requirement modeling tool basing on the research.The result of the research has been applied in a software product platform named D2G(design & development for government).更多还原
