Evaluation of product design concepts is important and critical problem. considering incomplete and imprecise information in the early stages of product design process. In order to overcome this problem. grey theory, fuzzy sets and information axiom are combined in this study under the name of grey-fuzzy information axiom for solving product concept evaluation problem for the first time. The information axiom has the capability to solve multi-attribute evaluation problems. Grey and fuzzy set theories are complementary methods for quantification uncertainty. Applicability of the proposed method is demonstrated on the evaluation of dishwasher design concepts. It has been shown that grey-fuzzy information axiom is an appropriate tool to be used for the concept evaluation problem in case of having different type of uncertainties.
