摘要： 为更好地对汽车产品性能进行量化评价,提出将模糊层次分析法(FAHP)引入模糊质量功能展开方法(FQFD)中,构建了一种新的汽车产品性能评价量化方法。首先,基于专家评价,运用模糊层次分析法求出不同汽车产品性能需求权重;然后,应用权重概率方法综合考虑顾客评价对权重进行修正;最后,在建立多阶段的模糊质量功能屋模型的基础上求出汽车产品的性能指标。以汽车发动机罩为例验证了这种方法的实施过程。结果表明,所构建的FAHP-FQFD评价方法可有效地对汽车产品性能进行量化评价,评价结论能较好地反映实际情况,为汽车设计方案选择提供了直观的科学依据。

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
