Abstract: Aiming at the problem of evaluation information was subjective and uncertain in product scheme selection process, and some shortcomings of existing research about product scheme selection, a new approach based on information axiom with 2tuple linguistic was proposed. Firstly, the method converted the linguistic assessment information of each expert to 2tuple linguistic, the group′s 2tuple linguistic decision matrix and the attribute weights vector of product schemes were calculated according to the 2tuple linguistic aggregation operator, and the attribute combination weights vector was determined. Then the 2tuple linguistic information content of product schemes were calculated based on information axiom and the best scheme was obtained with information content. The results in indicate that the proposed method can avoid the information loss in transferring and integrating the linguistic evaluation, combination weighting of attributes can fully reflect the subjective and objective, and the calculation is simple, accurate and effective in the product design scheme decision process, it has potentially practical value.
