Area ranking of fuzzy numbers based on positive and negative ideal points

open access: yesComputers and Mathematics With Applications, 2009
The maximizing set and minimizing set method is a popular ranking approach for fuzzy numbers, which ranks them based on their left, right and total utilities. This paper presents an alternative ranking approach for fuzzy numbers called area ranking based

On $\left( \in ,\in \vee q_{k}\right) $-Fuzzy KU-ideals of KU-algebras

Acta Universitatis Apulensis, 2014
In current paper we have defined \(\left( \mathbf {\alpha ,\beta }\right) \)-fuzzy KU-ideals of KU-algebras and then some useful characterizations have provided. Finally we have introduced the concept of \(\left( \mathbf {\alpha ,\beta }\right) \)-fuzzy KU-relation and then by the use of this notion we have proved some more interesting results.

Generalized approximations of $$\left( \in ,\in \vee q\right) $$ ∈ , ∈ ∨ q -fuzzy ideals in quantales

Computational and Applied Mathematics, 2018
Theory of rough sets is an important tool in data mining, algebraic systems, graph theory, partially ordered sets, etc. In the present paper, we are starting the investigation of roughness in $$(\in ,\in \vee q)$$

Some characterizations of ternary semigroups by the properties of their $\left( \in _{\gamma },\in _{\gamma }\vee q_{\delta }\right)$-fuzzy ideals

Journal of Intelligent & Fuzzy Systems, 2014
This paper is the continuation of our previous work “Some kinds of $\left( \in _{\gamma },\in _{\gamma }\vee q_{\delta }\right)$-fuzzy ideals of ternary semigroups” (N. Rehman and M. Shabir, Some kinds of $\left( \in _{\gamma },\in _{\gamma }\vee q_{\delta }\right)$-fuzzy ideals of ternary semigroups, Iranian Journal of Science and Technology Trans A ...

Welfare and immigration regimes: A fuzzy set ideal type analysis of immigrants’ social rights and responsibilities in 27 OECD countries

Asian Social Work and Policy Review, 2020
AbstractThis article studies the social rights and responsibilities of immigrants in an international comparative perspective, focusing on two main institutions underpinning immigrants’ social rights and responsibilities (i.e., the welfare regime and immigration regime of the host state). Drawing on literature about both welfare and immigration regimes,
