Abstract: The aim of this paper is to develop an interactive approach for multiple attribute decision making with incomplete weight information under uncertain linguistic environment.Some of the concepts are defined,such as the distance between two uncertain linguistic variables.This paper also defines the expectation level of alternative,the uncertain linguistic negative point,the achievement scale,the alternative comprehensive scale under uncertain linguistic environment.Based on these concepts,some linear programming models are established,through which the decision maker interacts with the analyst.Furthermore,a practical interactive approach is given for selecting the most desirable alternative(s).The interactive process can be realized by giving and revising the achievement scale and comprehensive scale of alternatives till the achievement scale and the comprehensive scale are achieved to the decision maker’s request.Finally,an illustrative example is also given.
