Abstract: To analyze the relative importance of customer requirement systematically, a new method by integrating market competitive information in product planning house of quality and Kano model to adjust the fundamental importance of customer requirements was proposed. The semantic information based decision-making theory was introduced to conduct competitive evaluation and aggregate group semantic information. On the basis of the results, the mean square deviation maximum model was contrusted, and goal performance level of customers satisfaction was improved. Thus the competitive importance as well as improved priority were obtained. The customer requirement's Kano classification was identified through double factor analysis of customer satisfaction and Kano factors were estimated. The basic importance of customer requirement was modified by competitive importance, improved priority, and Kano factors, and the integrated importance of customer requirements was determined. A certain industrial dust collection machine's improved design was taken as an example to demonstrate the rationality and validity of proposed method.
