A new method for fuzzy group decision-making based on interval linguistic labels

This paper presents a new method for dealing with fuzzy group decision-making problems based on interval linguistic labels. We propose the interval linguistic labels ordered weighted average (ILLOWA) operator to aggregate interval linguistic labels and propose likelihood-based comparison relations of interval linguistic labels to develop a new method to deal with fuzzy group decision-making problems. It provides us with a useful way to deal with fuzzy group decision-making problems.
