Uncertain linguistic aggregation operators based approach to multiple attribute group decision making under uncertain linguistic environment

In this paper, two uncertain linguistic aggregation operators called uncertain linguistic ordered weighted averaging (ULOWA) operator and uncertain linguistic hybrid aggregation (ULHA) operator are proposed. An approach to multiple attribute group decision making with uncertain linguistic information is developed based oil the ULOWA and the ULHA operators. Finally, a practical application of the developed approach to the problem of evaluating university faculty for tenure and promotion is given. (C) 2004 Elsevier Inc. All rights reserved.
