Abstract

Quality function deployment (QFD) was developed in Japan and used extensively by Toyota and its suppliers. The process results in a matrix, referred to as the “house of quality,” for a particular product that relates customer requirements to technical measures. Determining the relationship between customer requirements and technical measures is a typical group decision-making process in QFD by a cross-functional team. Generally, different and/or even subjective opinions are happened often in a group decision-making process due to the limitations of experience and vagueness. Obviously, the relationship between customer requirements and technical measures are determined by a group of people with imprecision and vagueness. Under such circumstances, a fuzzy group decision-making method can be applied in the relationship between customer requirements and technical measures of QFD to deal with a group decision-making process when the information is filled with imprecision and fuzziness. Moreover, an example is presented as well as the procedures to show how this fuzzy group decision-making method can be effectively used in QFD to make decisions with imprecision and vagueness.
