Application of Kano model-based QFD analysis method in the classify of aircraft requirements

This paper introduces a classification methodology of aircraft requirements on Quality Function Development(QFD) , which divides quality into Must-be Quality,One-dimensional Quality and Attractive Quality. Accordingly, the fuzzy clustering method is used to analyze the customer requirements in details, which determines the subordinate relationship of each kind of requirements information, outputs requirements classification results. Finally, the research method is applied to the classification design of aircraft requirements capture in order to prove its effectiveness.
