Group decision making situations are part of today’s organizations. It is a type of decision making involving many decision \nmakers which act collectively to choose the best alternative (or alternatives) from a set of feasible alternatives. Usually, numerical \nvalues have been used by the decision makers to express their opinions on the possible alternatives. However, as the standard \nrepresentation of the concepts that humans use for communication is the natural language, words or linguistic terms instead of \nnumerical values should be used by the decision makers to provide their preferences. In such a situation, the linguistic information \nhas to be made operational in order to be fully utilized. In this contribution, assuming that decision makers express their opinions by \nusing linguistic terms, we present an information granulation of such a type of information, which is formulated as an optimization \nproblem in which consistency is maximized by a suitable mapping of the linguistic terms on information granules.
