A Method Based on Similarity Scale for Multiple Attribute with Interval-Valued Intuitionistic Fuzzy Information

摘要

In this paper, a new method for the multiple attribute decision making problems with intervalvalued intuitionistic fuzzy information is presented. The concepts of interval-valued intuitionistic fuzzy positive ideal point and interval-valued intuitionistic fuzzy negative ideal point are defined. The formula for measuring the similarity between interval-valued intuitionistic fuzzy number is given. The method proposed here can provide a useful way to efficiently help the decision-maker to make his decision. Finally, an illustrative example is given.
