Abstract: For better conducting quantitative evaluation on the performances of automotive products, fuzzy analytic hierarchy process (FAHP) is introduced into fuzzy quality function deployment (FQFD), and a novel quantitative evaluation method for automotive products performance is created. Firstly, FAHP is used to calculate the requirement weights of different automotive products performances based on experts' evaluation. Then weight probability method is applied to revise weighting factors with comprehensive consideration of customers' evaluation. Finally, on the basis of setting up multi-stage fuzzy quality function house model, the performance indicators of automotive products are calculated. The implementation process of this approach is verified by an example of automotive engine hood. The results show that the FAHP-FQFD evaluation method created can effectively fulfill the quantitative evaluation on automotive product performances with their outcome better reflecting actual situation, providing intuitive scientific basis for the selection of vehicle design schemes

Key words: automotive products, performance evaluation, fuzzy analytic hierarchy process, fuzzy quality house
