A new outranking method for multicriteria decision making with complex Pythagorean fuzzy information

Abstract This article contributes to the advancement and evolution of outranking decision-making methodologies, with a novel essay on ELimination Choice Translating REality (ELECTRE) family methods. Its primary target is unfold constituents expound implementation ELECTRE II method for group decision making in complex Pythagorean fuzzy framework. results method. By inception, it intrinsically superior models using one-dimensional data. It designed perform pairwise comparisons alternatives core notions concordance, discordance indifferent sets, which then followed by construction concordance matrices. Further, strong weak relations are developed comparison indices levels. Later, forward, reverse average rankings computed dint graphs. methodology supported case study selection wastewater treatment process, numerical example best cloud solution big data project. consistency confirmed an effectiveness test analysis I
