摘要：Design quality has a great influence on the suc-cess of a product. And the product design quality can beevaluated by various mature in product developmentphases [1]. On the other hand, the design quality should beconsistently on product design target. More importantly,for the purpose of improving the level of product designquality, the suitable concept design is crucial [2]. In orderto facilitate the process of transforming product designquality objectives into effective actions, product qualitywould be considered by many engineering design require-ments (EDRs) [3]. In today’s rapidly evolving world ofmanufacturing industry, design quality of mechanical andelectrical products is more and more important [4]. Conse-quently, the aggregate analysis of product design optimiza-tion is a critical part for product quality during the designscheme decision processes [5].
