基于变动的设计过程模型研究

Study On Variation-based Design Process Model

设计过程的有效表示是实现CAD技术真正效能的关键。基于对设计过程变动特性的认识 ,将设计单元作为各产品组成环节的抽象 ,从理论上提出了描述设计过程的变动过程模型的形式化定义 ,并对其特点、作用、应用和研究进行了讨论。

Benefiting from advances in computer aided design technology in design can not be expected before the design processes are effectively represented.Based on recognizing the variation characters of design process,this paper introduces a new concept,design component,as an abstraction of product composition,and theoretically presents a new formal model definition,variational process model,for describing design process.Besides,some aspects of the proposed concepts including their features,functions,main applications and further researches are discussed.
