Multicriteria Decision Making Based on Interval-Valued Intuitionistic Fuzzy Sets with a New Kind of Accuracy Function

摘要

In this paper,we propose a newaccuracy function based on interval-valued intuitionistic fuzzy sets, then use this new accuracy function to multicriteria decision making method. By comparing the new accuracy function with other accuracy function, some examples are given. While aggregating fuzzy information, we use the interval-valued intuitionistic fuzzy weighted aggregation operators, and rank the fuzzy information by the proposed accuracy function, which overcomes some difficulties arising in some existing accuracy functions for determining rank of intervalvalued intuitionistic fuzzy information. Finally, the effectiveness and practicability of the proposed method are illustrated by examples.
