| Abstract: | In this paper,we study multiple attribute group decision making problem with uncertain linguistic information,in which the attribute weights and expert weights take the form of real numbers,and the preference values take the form of uncertain linguistic variables.An uncertain linguistic aggregation operator called uncertain linguistic hybrid geometric aggregation (ULHGA) operator is proposed.An approach to multiple attribute group decision making (MAGDM) with uncertain linguistic information is developed based on the ULWGM and the ULHGA operators.Finally,an illustrative example is given to verify the developed approach and to demonstrate its practicality and effectiveness. |
