Abstract :
The group decision making based on different preference of judgments is investigated. Based on the transformation between the triangular (trapezoidal) fuzzy number and 2-tuple linguistic, the different preference information is unified to 2-tuple linguistic information. It is illustrated by a numerical example that the proposed methods are effective.
