A mathematical approach to medical diagnosis via Pythagorean fuzzy soft TOPSIS, VIKOR and generalized aggregation operators

Abstract Hepatitis is a therapeutic disorder caused by the inflammation/infection of liver and regarded as existence cells causing inflammation in tissues body parts. deliberated lethal disease worldwide, especially developing countries mainly due to contaminated drinking water, unhygienic sanitary conditions careless blood transfusion. This infection basically considered viral even though this sort can also take place autoimmune, toxin, medications, unprotected physical relations, drugs alcohol. Many approaches identifying hepatitis have been sought so for, which include inspection, function tests (LFTs), surgery (biopsy), imaging studies such sonogram or CT scan, ultrasound, tests, serology panel, DNA test, antibody testing. In article, we propose mathematical analysis types using Pythagorean fuzzy soft sets (PFSSs) via TOPSIS (Technique for Order Preference Similarity Ideal Solution), VIKOR (Vise Kriterijumska Optimizacija Kompromisno Resenje) generalized aggregation operators models show that all three techniques render same optimal choice. We present commentary yielding comparison between considering their structure evaluation.
