Homomorphisms on the monoid of fuzzy implications and the iterative functional equation I(x,I(x,y))=I(x,y) [PDF]

open access: yes, 2015
Recently, Vemuri and Jayaram proposed a novel method of generating fuzzy implications, called the ⊛⊛-composition, from a given pair of fuzzy implications [Representations through a Monoid on the set of Fuzzy Implications, Fuzzy Sets and Systems, 247, 51 ...

A democratic preference aggregation model

open access: yes, 2013
We propose a democratic preference aggregation function using trapezoidal fuzzy numbers. Examples are constructed to illustrate the proposed technique to optimize the problem by avoiding paradoxical outcomes without the fear of indecision.2010 ...

On the property of T-distributivity

open access: yes, 2013
In this paper, we introduce the notion of T-distributivity for any t-norm on a bounded lattice. We determine a relation between the t-norms T and T′, where T′ is a T-distributive t-norm. Also, for an arbitrary t-norm T, we give a necessary and sufficient

Fuzziness and Funds Allocation in Portfolio Optimization [PDF]

open access: yes, 2002
Each individual investor is different, with different financial goals, different levels of risk tolerance and different personal preferences. From the point of view of investment management, these characteristics are often defined as objectives and ...

Interval valued $(\in,\ivq)$-fuzzy filters of pseudo $BL$-algebras

open access: yes, 2008
We introduce the concept of quasi-coincidence of a fuzzy interval value with an interval valued fuzzy set. By using this new idea, we introduce the notions of interval valued $(\in,\ivq)$-fuzzy filters of pseudo $BL$-algebras and investigate some of ...

A new type of soft multi rough sets

open access: yesDemonstratio Mathematica
Soft multi rough sets which are a hybrid model combining rough sets with soft multisets are defined by using soft multi rough approximation operators. Soft multi rough sets can be seen as a generalized rough set model based on soft multisets.

A first approach to an axiomatic model of multi-measures [PDF]

open access: yes, 2011
We establish an axiomatic model of multi-measures, capturing some classes of measures studied in the fuzzy sets literature, where they are applied to only one or two ...

Circular n,m-rung orthopair fuzzy sets and their applications in multicriteria decision-making

open access: yesDemonstratio Mathematica
The circular Pythagorean fuzzy set is an expansion of the circular intuitionistic fuzzy set (CIFS), in which each component is represented by a circle.
