We should aggregate the expert's evaluation information, and transform the 2-dimension linguistic evaluation information into 1-dimension linguistic evaluation information Z = [[[z.
28) is the weight vector of the three experts, and the attribute values given by the experts take the form of 2-dimension uncertain linguistic variables, shown in Tables 1, 2 and 3.
Transform the 2-dimension information into 1-dimension linguistic evaluation information and aggregate into the group decision matrix
Multiple attribute group decision making based on the 2-dimension uncertain linguistic variables are widely used in the real decision making.
