ABSTRACT: Quality function deployment (QFD) is the important product planning method that achieve customer requirements to map product function requirements, using QFD to transform the important degree of customer requirements into the important degree of product function requirements, and fully considering the interaction relationship between product function requirements, using DEMATEL method to modify the important degree of initial product function requirements. KANO model is the important method to analyze the type of customer requirements, using the KANO model to analyze product function requirements and to quantify the relationship between product function requirements and customer satisfaction degree, so that to obtain the function equation of customer satisfaction degree. Making the maximize customer satisfaction degree as the optimization goal to establish nonlinear programming model, and to determine the final optimization solution of product function requirements. Instance is given to demonstrate the feasibility and effectiveness of the proposed method.
