How to develop products becomes very important issue to fill the bill of consumers in companies. The relations of needs of customers into the quality of the product elements of the conversion influence the success or failure of new products. The Kano model is the tool to be developed to solve the questions changes and classifies the demands for products into clear quality factors. That model provides the different customers the quality factors in proper order to improve, the relations of consumer satisfaction and quality factors to explain, and provides plans of the quality designing in the companies. However, in the traditional Kano model, customers choose only one answer in all questions. In fact, the answers are often vague and uncertain, and are not all to nothing. Therefore traditional Kano model does not reflect the vague and uncertain opinions of the customers. So the research which combines fuzzy theory and the study of Kano Model, which try to press close to the opinions of consumers demands and increase the accuracy of product design. The research model is divided into two parts. First, the first model show the degree of the questionnaire to define the meaning values according to answers of the customers choose to express their feelings, the answers to find the quality of the classification of elements in Kano model, and the answers can choose one and the others not only choose one. The second Model shows the fuzzy single point to respondents of the answers feelings, and similar repeat the steps to find the quality elements in Kano model. The objectives in the research are in order to find the targets of better to increase and worse to decrease according to the results in two models, and make the better-worse graph. The graph shows to increase, decrease, improve and keep the qualities to increase customer satisfaction. Finally, the case study to be used the comparison between the traditional Kano model and the new Kano Model to measure the feasibility and practicality in this research. The results show the fuzzy Kano model can not only help researchers obtain more accurate and complete information, but also decrease the times of product design in product designing and manufacturing.
