A decision-making method based on grey interval linguistic judgment matrix

In this paper, decision-making based on the interval linguistic judgment matrix which may contain extreme programs or extreme decision-makers was studied. In the decision-making process, the boundaries of the programs or decision-makers can be found according to the interval linguistic judgment matrix if there are extreme programs or decision-makers; a method of amending the known elements is given based on the consistency of the matrix. Moreover, the weights are also solved in the form of interval number and the programs are compared according to the possibility degree.
