摘要
产品需求源自于产品生命周期的各个阶段 ,而经过明确定义和分解的产品需求 ,又是产品开发各个活动的设计目标。研究了产品需求的获取方法 ,通过对用户需求、产品开发过程及其各个应用系统的相关活动和数据的分析 ,建立设计系统和产品本身之间的联系 ,获取产品开发活动的设计需求信息 ;探讨了基于产品结构和产品开发过程的产品需求结构化建模方法 ;采用形式化描述语言EXPRESS -G ,建立了一种相对通用的产品需求信息模型 ,以及产品。
The product requirements exist in all stages of product lifecycle and are the objectives of design activities after identified and decomposed definitely. The methodology of product requirements capturing based on the investigation of information and related activities of customer requirements, product development processes and application systems is studied, to connect the product and its design system and to capture the information of product development processes and its related requirements. A formalized way for product requirements modeling which based on product structure and product development processes is proposed. The relationship of product, product requirement and design activities is established. Then a proposed product requirement model is given, which is described by the EXPRESS-G formal graphical notation.
