Abstract: Quality function deployment (QFD) is one such extremely important quality management tool that is useful in product design and development. Traditionally, QFD rates the design requirements (DRs) with respect to customer needs, and aggregates the ratings to get relative importance score of DRs. An increasing number of studies emphasise on the need to incorporate additional factors (AFs), such as cost and environmental impact, while calculating the relative importance of DRs. However, there are varieties of methodologies for deriving the relative importance of DRs, when several AFs are considered. Fuzzy technique for order preferences by similarity to ideal solution (TOPSIS) and analytic hierarchy process method are suggested for the purposes of this paper. This paper proposes new approach of fuzzy TOPSIS for considering the ratings of DRs with respect to CRs, and several AFs simultaneously. Proposed method is illustrated, using a step-by-step procedure. The proposed fuzzy QFD–TOPSIS methodology was applied for the Aras pen company in Iran.
