Abstract: In the process of products design, most input information for quality function deployment always shows as the judgment, understand and evaluation of human, which possess the characteristics of fuzziness and language. The main idea of modeling of fuzzy information with house of quality is explained, and fuzzy integrating of custom needs and fuzzy modeling of products planning with HOQ are proposed. With the fuzzy expantion theory, the traditional quality house theory and method are applied into the fuzzy fields. The modeling of fuzzy information is discussed with fuzzy arithmetic, fuzzy decision-making. Thus, the fuzzy or qualitative information can be dealt with efficiently, and the significative decision in fuzzy circumstance can be made.

Key words: Quality function deployment Fuzzy information modeling Fuzzy decision-making
