ABSTRACT
In the interval Pythagorean fuzzy environment, the existing score function ignores the influence of interval hesitation on decision-making, and there are problems of many calculation steps and small difference between calculated values. Aiming at this situation, the existing score function of interval Pythagorean fuzzy sets is deeply analyzed, an improved new score function is defined, and its related theorems and properties are proved.

Robustness of interval-valued fuzzy inference
Since interval-valued fuzzy set intuitively addresses not only vagueness (lack of sharp class boundaries) but also a feature of uncertainty (lack of information), interval-valued fuzzy reasoning plays a vital role in intelligent systems including fuzzy ...
Interval-valued intuitionistic fuzzy generators: Application to edge detection
In this paper, a method for edge detection in digital images based on the interval-valued intuitionistic fuzzy concepts is presented. We propose a novel method to generate the Interval-Valued Intuitionistic Fuzzy Sets (IVIFS) from Interval-Valued Fuzzy ...
A bipolar-valued fuzzy set is an intersected interval-valued fuzzy set
AbstractThis paper shows that a bipolar-valued fuzzy set and a special interval-valued fuzzy set, whose cut-off point of left and right ends of the interval-valued membership is λ ( 0 < λ < 1 ), are identical from a mathematical point of view. All ...
