Abstract: Background: This study proposes a triangular fuzzy number multi-attribute decision-making method based on set-pair analysis, to solve the problems with multi-attribute decision-making, with both the attribute value and the attribute weight being triangular fuzzy numbers. Materials and Methods: This method integrates the set-pair analysis theory and converts the attribute values and the attribute weight of the triangular fuzzy number into identical-different dual connection numbers, in an effort to build the absolute positive ideal connection number and absolute negative ideal connection number of the attribute values and calculate the absolute positive and negative ideal connection number distance in various schemes. Results: This way, the relative connection number distance can be determined and used to rank the schemes. Conclusion: At last, the study results demonstrate the feasibility and validity of the proposed method through analysis of examples.
