Abstract: Quality function deployment (QFD) is an important tool available for organisations for efficient 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, such as cost and environmental impact, while calculating the relative importance of DRs. However, there is a variety of methodologies for deriving the relative importance of DRs, when several additional factors are considered. Technique for order preferences by similarity to ideal solution (TOPSIS) method is suggested for the purposes of the paper. This paper proposes TOPSIS for considering the ratings of DRs with respect to CRs, and several additional factors. Proposed method is illustrated using a step-by-step procedure. The proposed QFD-TOPSIS methodology was applied for the design of TV in Pars Electric Company in Iran.
