Intuitionistic fuzzy geometric Heronian mean aggregation operators

Applied Soft Computing, 2013
In this paper, the multi-criteria decision making problem with the assumption that the criteria are correlative is studied under intuitionistic fuzzy environment. Some new aggregation operators for intuitionistic fuzzy information are proposed, including the intuitionistic fuzzy geometric Heronian mean (IFGHM) operator and the intuitionistic fuzzy ...

Further inequalities involving the weighted geometric operator mean and the Heinz operator mean

Linear and Multilinear Algebra, 2021
In this paper, we first investigate some inequalities involving the p-weighted geometric operator mean A ♯ p B = A 1 / 2 ( A − 1 / 2 B A − 1 / 2 ) p A 1 / 2 ,  where p ∈ [ 0 , 1 ] is a real number ...

Uncertain Linguistic Hybrid Geometric Mean Operator

Fourth International Conference on Fuzzy Systems and Knowledge Discovery (FSKD 2007), 2007
With respect to multiple attribute group decision making problem with uncertain linguistic information, in which the attribute weights and expert weights take the form of real numbers, and the attribute preference values take the form of uncertain linguistic variables, an uncertain linguistic aggregation operator called uncertain linguistic hybrid ...

Dynamic Uncertain Linguistic Weighted Geometric Mean Operator

2008 Fifth International Conference on Fuzzy Systems and Knowledge Discovery, 2008
With respect to multiple periods multiple attribute decision making problems with uncertain multiplicative linguistic preference relations. Definition and some operational laws of uncertain linguistic variables are introduced, and two new operators called dynamic uncertain linguistic geometric mean (DULGM) operator and dynamic uncertain linguistic ...

Following the Trail of the Operator Geometric Mean

2020
This paper traces the development of the theory of the matrix geometric mean in the cone of positive definite matrices and the closely related operator geometric mean in the positive cone of a unital C∗-algebra. The story begins with the two-variable matrix geometric mean, moves to the n-variable matrix setting, then to the extension to the positive ...
