Abstract: In practical multiple-attribute decision making problems, sometimes there are correlations between attributes, and attribute values are given in the form of uncertain language. In order to solve the multiple-attribute decision making problems with correlations between attributes in uncertain linguistic environment, the uncertain linguistic generalized weighted Heronian mean(ULGWHM)operator is given, and its properties are studied, including idempotency, boundedness, monotonicity, permutation and limit properties. Then a multiple-attribute decision making method based on this operator is presented. Finally, the feasibility of multiple-attribute decision making method based on ULGWHM operator is illustrated by an example.

Key words: multiple-attribute decision making, attribute association, Heronian mean, uncertain linguistic generalized weighted Heronian mean
