Abstract

Because of the complexity of limitation and realistic decision of decision knowledge, multiple attribute decision making problems with the attribute value often need to characterize fuzzy number. The triangular fuzzy number to describe this kind of ambiguity is very effective and for the project investment selection problem with triangular fuzzy numbers, this study puts forward a new multiple attribute decision making method. The concrete steps are: we first define the left and right scores based the normalized triangular fuzzy numbers and then the decision matrix is transformed into the interval number decision-making matrix. Finally the distance based on alternative and ideal solution as the principle of optimal alternatives for sorting and merit. At the end of the study, an example is given to show that the method proposed in this study is effective and practical.

Keywords:

Ideal solution, left and right scores, multiple attribute decision making, triangular fuzzy number,
