the purpose of this paper is to develop a methodology for solving a new type of matrix games in which payoffs are expressed with triangular intuitionistic fuzzy numbers (tifns). in this methodology, the concept of solutions for matrix games with payoffs of tifns is introduced. a pair of auxiliary intuitionistic fuzzy programming models for players are established to determine optimal strategies...

Single-minute exchange of dies (SMED) is one the most significant lean tools which reduces required time for setup operations. The consideration appropriate ergonomic interferences during SMED implementation improves working conditions, productivity, and flexibility. literature has an opportunity expansion with assessment. Moreover, assessment studies have various limitations in terms a broad h...

In this paper, we introduce  the notions of   interval-valued and $(in,ivq)$-interval-valued fuzzy ($p$-,$q$- and $a$-) ideals    of   BCI algebras   and investigate some of their properties.   We then derive characterization theorems for these generalized interval-valued fuzzy ideals  and discuss their relationship.

The linguistic interval-valued Pythagorean fuzzy (LIVPF) sets, which absorb the advantages of terms set and can efficiently describe decision makers’ evaluation information in multi-attribute group decision-making (MAGDM) problems. When investigating aggregation operators information, we have to consider two important issues, viz. operational rules LIVPF numbers functions. classical Archimedean...

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...
