Vague soft set relations and functions

Journal of Intelligent & Fuzzy Systems, 2015
Molodtsov introduced the theory of soft sets as a generalized tool for modelling complex systems involving uncertain or not clearly defined objects. In this paper the concepts of vague soft set relations are introduced as a sub-vague soft set of the Cartesian product of the vague soft sets and related concepts such as equivalent vague soft set relation,

Relations between complex vague soft sets

Applied Soft Computing, 2016
Display Omitted Complex vague soft sets (CVSSs for short) are a hybrid model of complex fuzzy sets and vague soft sets and the study of CVSSs was initiated by Selvachandran et al. (2016).In this paper, the Cartesian product and the composition of CVSSs are defined and these are used to introduce the relations between CVSSs.This relations are then ...

Vague soft expert set theory

AIP Conference Proceedings, 2013
The concept of fuzzy soft expert set theory and its operations were reviewed. The concept of vague soft expert set theory is introduced. Its operations such as equal, subset, complement, union and intersection are defined. Illustrative examples of vague soft expert set are then given.

Einstein-operations on vague soft set

AIP Conference Proceedings, 2017
We define Einstein product and Einstein sum of vague soft sets and using these operations, we introduce an adjustable approach to vague soft set based decision-making, for solving decision-making in uncertain situation. The feasibility of our proposed vague soft set based decision-making procedure in practical application is shown by some numerical ...

Vague Soft Hemirings

Computers and Mathematics With Applications, 2011
Xu et al. introduced the concept of vague soft sets, which is an extension to the soft set and the vague set. In this paper, we apply the concept of vague soft sets to hemiring theory.

Characterization of vague hyper soft alpha open sets.

J. Intell. Fuzzy Syst., 2022
In our work, we defined new operations in a new way in connection with vague hyper soft sets. These operations are vague hyper soft sets, vague hyper soft subsets, vague hyper soft complements, vague hyper soft null sets, vague hyper soft absolute sets, vague hyper soft union and vague hyper soft intersection. On the basis of these new operations vague

Complex vague soft sets and its distance measures

Journal of Intelligent & Fuzzy Systems, 2016
In this paper, we propose the concept of complex vague soft sets which are vague soft sets defined in a complex setting. Based on this new concept we define some concepts related to this notion as well as some basic operations namely the complement, union, intersection, AND and OR.

Vague parameterized vague soft set theory and its decision making

Journal of Intelligent & Fuzzy Systems, 2017
In this paper, we first define vague parameterized vague soft sets (vpvs-sets) and study some of their properties. We then introduce vpvs-aggregation operator to form vpvs-decision making method that allows constructing more efficient decision processes.

Generalized vague soft expert set theory

AIP Conference Proceedings, 2013
The concept of generalized vague soft expert set and its operations are studied. Also, the multi-opinion of generalized vague soft expert set in a decision making problem with uncertainty is introduced. The basic operations of generalized vague soft expert set theory, namely, complement, subset, union, intersection, “AND” and “OR” operations are ...

Decision making based on similarity measure of vague soft sets

Journal of Intelligent & Fuzzy Systems, 2013
In this paper the notion of similarity between vague soft sets have been introduced. Two types of measures of similarity have been introduced which are based on Hausdorff metric and set theoretic approach respectively. Some properties of these measures have also been studied.
