Atanassov presented the dominant notion of intuitionistic fuzzy sets which brought revolution in different fields science since their inception. The operations t-norm and t-conorm introduced by Dombi were known as operational parameter possesses natural flexibility with resilience variability. advantage is very important to express experts’ attitude decision-making. This study aims propose roug...

Aggregation operators perform a valuable and significant role in various decision-making processes. Averaging geometric aggregation are both used for capturing the interrelationships of aggregated preferences, even if preferences independent. The purpose this paper is to analyze theory complex linguistic fuzzy (CLF) sets their important laws, such as algebraic score values, accuracy describe re...

With respect to multiple criteria group decision-making (MCGDM) problems in which both the weights and expert take form of crisp numbers attribute values interval-valued picture fuzzy uncertain linguistic numbers, some new analysis methods are developed. Firstly, operational laws, expected value, accuracy function introduced. Then, an averaging geometric aggregation operators Furthermore, desir...

We analyze different types of aggregation operators. We focus on the generalized OWA (GOWA) operator and the Quasi-OWA operator which generalize a wide range of aggregation operators. We also analyze a recent approach that unifies the weighted average and the OWA operator in the same formulation called ordered weighted averaging – weighted averaging (OWAWA) operator. We introduce the fuzzy gene...

The objective of this paper is to introduce some new logarithm operational laws for intuitionistic fuzzy sets. Some structure properties have been developed and based on these, various aggregation operators, namely confidence logarithmic Einstein weighted geometric (CLIFEWG) operator, ordered (CLIFEOWG) hybrid (CLIFEHG) averaging (CLIFEWA) (CLIFEOWA) (CLIFEHA) operator presented. To show the va...

Methods for aggregating intuitionistic trapezoidal fuzzy information are investigated. Some operational laws of intuitionistic trapezoidal fuzzy numbers are introduced. Based on these operational laws, some aggregation operators, including intuitionistic trapezoidal fuzzy ordered weighted averaging (ITFOWA) operator and intuitionistic trapezoidal fuzzy hybrid aggregation (ITFHA) operator, are p...

The first aim to this paper is introduce the notions of bipolar fuzzy soft metric space and (D-)metric space. In order define these concepts, concept points has been brought literature have examined in detail. Moreover, sequences cauchy were defined some their properties examined. addition all this, many examples are given better understand concepts features studied contribute a understanding p...
