Yang Xiao-juan · Shuxue de shijian yu renshi · 2011
For the problem of trapezoidal fuzzy argument information aggregation,the formula of possibility degree for the comparison between two trapezoidal fuzzy numbers and the trapezoidal fuzzy ordered weighted geometric(TFOWG) operator are proposed.Based on the formula of possibility degree and the TFOWG operator,an approach is developed for solving uncertain multiple criteria decision making problems,in which the criteria weights are completely unknown and the criteria values are trapezoidal fuzzy numbers.Finally,an illustrative example is given to show the feasibility and effectiveness of this method.
