Abstract: In terms of the requirements information's uncertainty,fuzziness and dynamics in the process of constructing house of quality,a method for analyzing customer requirements' priority ratings and sensitivity based on intuitionistic fuzzy sets was proposed.By considering the decision-maker's heterogeneity fully,the initial evaluation information was given in various forms,and eventually unified into an intutionistic fuzzy set.An improved Kano model based on customer requirements preference was proposed to determine the correction factor of customer requirements.The initial evaluation information with correction factor were integrated to analyze the comprehensive priority ratings of customer requirements.A sensitivity analysis was made for the priority ratings of customer requirements with consideration of customer requirements' dynamic characteristic.An analysis of customer requirements' priority ratings and sensitivity of a technical company's software system were taken as the example to certify the efficiency and feasibility of the proposed method.

Key words: intuitionistic fuzzy sets, customer requirements, quality function deployment, house of quality, priority ratings, sensitivity analysis
