Abstract: Aiming at the deficiency of traditional Quality Function Deployment (QFD) in considering function requirement self-correlation,a fuzzy QFD was employed to translate the importance degrees of Customer Requirements (CRs) into the importance degrees of Function Requirements (FRs).Based on fuzzy DEMATEL method,the mutual influence relationships among FRs was analyzed,and the initial importance degrees of FRs was amended.Fuzzy KANO questionnaire was employed to analyze the category of FR,and the quantitative functional relationship between customer satisfaction degree and FRs were obtained based on KANO model.The programming model for optimizing the fulfillment levels of FRs was established to maximize the customer satisfaction degree.An example was given to demonstrate the feasibility and effectiveness of the proposed approach.
