Selection of solar tracking system using extended TOPSIS technique with interval type-2 pythagorean fuzzy numbers

Abstract The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is considered among the most frequently used techniques deal with multi-criteria group decision-making (MCGDM) conflicts. In this article, we have presented an extended TOPSIS technique in framework of interval type-2 trapezoidal Pythagorean fuzzy numbers (IT2TrPFN). We first projected a novel approach evaluate distance between them using ordered weighted averaging operator and $$(\alpha ,\beta )$$ ( α , β ) -cut. Subsequently, widen concept method formed on IT2TrPFNs applied it MCGDM dilemma considering attitudes perspectives decision-makers. Lastly, application solar tracking system numerous contrasts other existing are express practicality feasibility our approach.
