A FUZZY-LOGIC BASED GROUP DECISION-MAKING APPROACH IN QUALITY FUNCTION DEPLOYMENT

摘要

A fuzzy-logic based group decision-making approach in quality function deployment (QFD) is proposed in this study to devise the product improvement strategy for companies. We extend the QFD methodology by introducing a new group decision-making approach that takes multiple preferences formats into account and by fusing different expressions into one uniform group decision by means of fuzzy set theory. Finally, a case study for "Portable Entertainment and Game Systems" design is given to demonstrate the potential of the proposed approach.
