Convex and Concave Sets Based on Soft Sets and Fuzzy Soft Sets

Journal of New Theory, 2019
In this study, after given somebasic definitions of soft sets and fuzzy soft sets we firstly defineconvex-concave soft sets. Then, we investigate their properties and give somerelations between convex and concave soft sets.

ON SOFT EXPERT SETS

Journal of New Theory, 2015
Alkhazaleh and Salleh defined the concept of soft expert sets [Advances in Decision Sciences, Article ID 757868, 2011]. In this paper, we make some modification to the soft expert sets. On the modified soft expert sets we then construct a decision making

A New Operation on Soft Sets: Extended Difference of Soft Sets

Journal of New Theory, 2019
Soft Set Theory, which has been considered as an adequate mathematical device, was proposed by Molodtsov to deal with ambiguities and uncertainties. Several operations on soft sets were defined in many soft set papers.

Neutrosophic soft matrices and its application in medical diagnosis [PDF]

Journal of Fuzzy Extension and Applications, 2021
In real life situations, there are many issues in which we face uncertainties, vagueness, complexities and unpredictability. Neutrosophic sets are a mathematical tool to address some issues which cannot be met using the existing methods.

Soft Rω-Open Sets and the Soft Topology of Soft δ_ω-Open Sets

Axioms, 2022
The author devotes this paper to defining a new class of soft open sets, namely soft Rω-open sets, and investigating their main features. With the help of examples, we show that the class of soft Rω-open sets lies strictly between the classes of soft ...

Soft Expert Sets [PDF]

Advances in Decision Sciences, 2011
In 1999, Molodtsov introduced the concept of soft set theory as a general mathematical tool for dealing with uncertainty. Many researchers have studied this theory, and they created some models to solve problems in decision making and medical diagnosis, but most of these models deal only with one expert.

The Bijective N-soft set decision system

AIMS Mathematics, 2023
The characteristics of many decision-making problems in an N-soft set environment are that the parameters consist of condition and decision parameters of which each alternative is only related to one parameter, and the union of partition by parameter ...

Possibility Fuzzy Soft Set [PDF]

Advances in Decision Sciences, 2011
We introduce the concept of possibility fuzzy soft set and its operation and study some of its properties. We give applications of this theory in solving a decision-making problem. We also introduce a similarity measure of two possibility fuzzy soft sets and discuss their application in a medical diagnosis problem.

On Fuzzy Soft Sets [PDF]

Advances in Fuzzy Systems, 2009
We further contribute to the properties of fuzzy soft sets as defined and studied in the work of Maji et al. ( 2001), Roy and Maji (2007), and Yang et al. (2007) and support them with examples and counterexamples. We improve Proposition 3.3 by Maji et al., (2001).
