Considering the matrix of QFD, we can take the customers needs into consideration only. However, we present a technique that can take into account the production constraints in the product design process as well as the customer needs. In this regard, the DEA technique which is a linear based model is proposed here. First, we discuss about the literature review on the context of QFD and DEA, and after explaning the combination process of these techniques a case study is represented. The tile industry case study proposed here takes into consideration the customer needs, their relative importance, constraints against the producers, and design requirements in the specified field. We evaluate not only the relationship between the customer needs and design requirements but we evaluate the relationship between the design requirements and producers constraints. Finally, by constructing the model using DEA and the regarding constraints we calculate the relative importance of design requirements.</em></span> QFD )گسترش عملکرد کیفیت(، DEA )تحلیل پوششی داده ها(، نیازمندی های مشتریان،الزامات طراحی، اهمیت نسبی.
