公理设计中确定交互作用程度的方法

METHOD OF DETERMINING THE INTERACTION STRENGTH AMONG FUNCTIONAL REQUIREMENTS IN AXIOMATIC DESIGN

公理设计是设计领域的通用理论,为设计提供一个理论框架,但是没有考虑功能要求间交互作用程度问题,使该理论在解决存在交互作用的现实工程设计时产生困难。将网络分析法(ANP理论)应用于公理设计中功能要求间交互作用的研究,在分析研究的基础上建立功能要求间交互作用的ANP理论通用模型,提出交互作用的测评算法,提出判断交互作用可否忽略的两个判据与判别方法。该方法为设计人员指明改进设计的方向,加速设计进程并得到实例验证的支持。

The axiomatic design is a general design method, which provides a theoretical framework for design evaluation.However, the interactions among functional requirements have not been considered, resulting in difficulties in practical engineering design. In this research, analytic network process （ANP） theory is applied to study the interactions. A general model of ANP for the interactions is proposed. An algorithm for measuring the interactions is also developed. Two methods and corresponding criteria of identifying whether or not the interactions can be ignored are proposed. The result may guide designers to improve design and speed up the design process. This method is demonstrated by using an example.
