质量功能展开的模糊信息建模过程

针对产品设计过程中,质量功能展开(QFD)所需要的大部分输入信息通常具有模糊化和语言化的特点,将质量屋(HOQ)中的各种输入变量看成是语言变量,建立了各语言变量的模糊语言术语集及其对应的模糊数,并应用模糊扩展原理将传统的HOQ理论与方法扩展到模糊领域中.运用模糊数四则运算、模糊决策、模糊推理等理论,详细论述了模糊信息的建模过程,对模糊环境下的产品设计决策具有理论意义.

Modeling Process of Fuzzy Information During Quality Function Deployment

In the process of product design,most input information necessary for quality function deployment(QFD) usually possesses the fuzzy and linguistic characteristics.So,various input information of house of quality(HOQ) are regarded as linguistic variable to compile a glossary of fuzzy terms for various linguistic variables and form the fuzzy numbers corresponding to them,with the conventional HOQ theory extended to fuzzy domain on the principle of fuzzy expansion.Elaborates the modeling process of fuzzy information by such theories as four arithmetic operations,fuzzy decision and fuzzy reasoning,which is of theoretical significance to the decision-making of products' design in fuzzy circumstances.
