Fuzzy multicriteria decision making in medical diagnosis using an advanced distance measure on linguistic Pythagorean fuzzy sets

Decision making is becoming one of the most vast research fields in medical science. Since last few years, the role of distance measure utilizing fuzzy sets in decision science has been significantly increased. A lot of studies have been carried out form the field of fuzzy decision making using distance measures. In this paper, Linguistic Pythagorean fuzzy sets have been utilized medical diagnosis problem. In addition, a novel distance measure on Linguistic Pythagorean fuzzy sets has been introduced and utilized in a fuzzy MCDM approach. Also, a case study is carried out in real data sets to show the usability and reliability of our proposed distance measure
