【Abstract】 A new approach to the evaluation of product design concept by a group of experts under fuzzy environment was presented. The weights of different criteria and the ratings of various alternatives under different criteria were evaluated in linguistic terms represented by fuzzy numbers. Fuzzy value of each of the alternatives was computed by making use of standard fuzzy arithmetic. The fuzzy distance measure is introduced to determine the final ranking of all alternatives. A web-based system was developed to facilitate the evaluation procedure. Finally, an example was given to demonstrate the effectiveness and robustness of the proposed approach.更多还原
