摘要: 以FCBR和AHP混合机制为基础构建一个面向产品概念设计的系统架构,该架构将模糊集原理应用于CBR,解决了概念设计时用户需求描述的不确定与不规范性问题,得到符合设计要求的评价模块集,应用AHP方法对评价案例集进行功能指标和经济指标上的评价,从而获得最合适的候选设计方案,通过调用功能改写案例库中的改写规则来修改候选案例得到最终优化方案。应用实例表明,在概念设计中使用该混合机制可以为用户提供有效的设计决策。

Abstract: This paper constructs a system structure which is used for conceptual design on the basis of FCBR and AHP. The structure combines the fuzzy set theory with CBR to solve the problem that most design requirements described by users are uncertain and nonstandard. After retrieving the competent evaluation cases set, the system uses AHP method to evaluate the function and economy indexes of the cases set, attains the most appropriate design candidate, and achieves the final optimized scheme by transfering the adaptation rules of the function adaptation cases to modify the design candidate. The application result shows that the hybrid mechanism can provide the designers with effective design decision during conceptual design.

Key words: fuzzy set theory, Fuzzy Case-based Reasoning(FCBR), Analytic Hierarchy Process(AHP), conceptual design, design decision-making
