Abstract: The multi-attribute decision making problem is studied in this paper,in which the information on alternatives preference is given in the forms of triangular fuzzy reciprocal judgment matrix.Firstly,we introduce the fuzzy C-OWG(FC-OWG)operator,and the expected fuzzy C-OWG(EFC-OWG)operaor, and study some of its charact eristics.Based on these operators,we develop a new method for priority of triangular fuzzy number reciprocal judgment matrix,which is adjusted according to decision-maker's preference degree.The method to make sensitivity analysis for the results by decision-maker's preference degree is proposed.Anumerical example shows the new method is easier to calculate,feasible and effective.

Key words: triangular fuzzy reciprocal judgment matrix, FC-OWG operator, EFC-OWG operator, priority
