Abstract The linguistic Pythagorean fuzzy sets (LPFSs), which employ terms to express membership and non-membership degrees, can effectively deal with decision makers’ complicated evaluation values in the process of multiple attribute group decision-making (MAGDM). To improve ability LPFSs depicting information, this paper generalized cubic (CLPFSs) studied CLPFSs-based MAGDM method. First, def...

The Pythagorean fuzzy soft set (PFSS) is the most proficient and manipulative leeway of (PFS), which contracts with parameterized values alternatives. It a generalized form intuitionistic (IFSS), provides healthier more accurate evaluations through decision-making (DM). main determination this research to prolong idea Einstein’s aggregation operators for PFSS. We introduce Einstein operational ...

In Suichang gold mine, the altered rock type deposits were cut by faults and joint fissures, leading to complex resource endowment characteristics, large changes in occurrence, a serious of ore vein branches great difficulty mining. order select suitable mining method for such difficult complicated orebody, multi-factor multi-index comprehensive evaluation system involving benefits, costs, safe...

in this paper, a new definition of fuzzy bounded sets and totallyfuzzy bounded sets is introduced and properties of such sets are studied. thena relation between totally fuzzy bounded sets and n-compactness is discussed.finally, a geometric characterization for fuzzy totally bounded sets in i- topologicalvector spaces is derived.

Interval-valued Pythagorean fuzzy sets (IVPFSs) as enhanced type of (PFSs) improve the expression degrees membership, non-membership and hesitancy in comparison with intuitionistic (IFSs). In this paper, to use advantages IVPFSs a new group decision-making method is introduced based on linear assignment (LAM). approach, subjective objective weights criteria are taken into account. Moreover, app...

The aim of this paper was to explore decision-making using Pythagorean fuzzy sets with an acronym in Portuguese for Interactive multi-criteria decision making (TODIM) approach. We propose a novel model that TODIM integrates the technique order preference by similarity ideal solution (TOPSIS) and concepts solve problems related core alternatives facing innovative companies under bullwhip effect ...
