Abstract: A hybrid multiple attributes evaluation problem for product scheme was studied including real number, interval number and fuzzy number. Based on Suhs information axiom, a new evaluation method was presented considering uncertain design scope of evaluation index. Method and process of evaluation were also provided. Through determining probability of each alternative satisfying functional requirements and computing information content of all alternatives, all evaluation schemes were compared and ranked by information content. For decision-makers, it was not necessary to provide the weight factors of evaluation index and normalize decision matrices. Therefore, the suggested method provided a new way to solve hybrid multiple attributes evaluation problem. Finally, to illustrate the feasibility of the proposed approach, the evaluation scheme of truck crane was provided.
