Abstract: Aiming at the problem that the current importance calculation of customer requirements was based on the independency among customer requirements,which ignored the internal relationship among customer requirements and the guiding role of design specifications,a method of weight calculation and transformation for customer requirements based on double layer association was proposed.A double layer association network including design specifications control layer and customer requirements network layer was established.An analytic network process was used to calculate the dominance relations and feedback relations between customer requirements as well as different design specifications and customer requirements.Therefore more accurate and effective customer requirements importance was obtained.The importance of customer requirements was transformed into the importance of technical feature through the relation matrix of quality function deployment,thereby guiding the designer to form an effective design direction and corresponding design strategies.The validity and practicability of the method were verified by the examples of high pier bridge pedestal.

Key words: customer requirements, weight calculation, double layer association analysis, quality function deployment, product design
