A Consistency Check Method for Trusted Hesitant Fuzzy Sets with Confidence Levels Based on a Distance Measure

Abstract EN

This paper proposes a consistency check method for hesitant fuzzy sets with confidence levels by employing a distance measure.

Firstly, we analyze the difference between each fuzzy element and its corresponding attribute comprehensive decision value and then obtain a comprehensive distance measure for each attribute.

Subsequently, by taking the relative credibility as the weight, we assess the consistency of hesitant fuzzy sets.

Finally, numerical examples are put forward to verify the effectiveness and reliability of the proposed method.
