Application research of fuzzy synthetic evaluation in product sculpt design

As to improve the evaluation ability of product sculpt design case, the combination of knowledge based (KB) and case based (CB) framework is presented. By researching industrial design problem-solve field knowledge, capturing evaluation factors and their weight quotients, quantifying the evaluation of fussy information, it is presented a framework of KB product evaluation system. The image scale 3D space is under construction through experiments with the image orientation of products. According to the spatial distance of the Euclidian, some descriptive comments will be made judging from the relationship between the design case and the classical market cases. So, a formalized, scientific gist of reasoning decision-making is presented for product design.
