A Multi-attribute Decision Making Method Based on Dynamic Triangle Fuzzy Numbers

摘要

With regard to the multi-attribute decision making problem wherein the attribute values are triangle fuzzy numbers, through considering the time weight and attribute weight at different time periods, we proposed a multi-attribute decision making method based on dynamic triangle fuzzy number. By adopting the characteristics of triangle fuzzy number, this method can help build the correlation model between evaluation scheme and positive & negative ideal scheme, so as to realize the comprehensive ranking of evaluation scheme and to obtain the decision results. At last, this paper verified the feasibility and effectiveness of this method by taking the evaluation of supplier selection plan as an example.
