Oriented Fuzzy Numbers vs. Fuzzy Numbers

open access: yesMathematics, 2021
A formal model of an imprecise number can be given as, inter alia, a fuzzy number or oriented fuzzy numbers. Are they formally equivalent models? Our main goal is to seek formal differences between fuzzy numbers and oriented fuzzy numbers.

Chromatic Number of Resultant of Fuzzy Graphs

open access: yesFuzzy Information and Engineering, 2016
Fuzzy graph coloring techniques are used to solve many complex real world problems. The chromatic number of complement of fuzzy graph is obtained and compared with the chromatic number of the corresponding fuzzy graph.

An efficient parallel greedy algorithm for fuzzy hybrid flow shop scheduling with setup time and lot size: a case study in apparel process [PDF]

open access: yesJournal of Fuzzy Extension and Applications, 2022
This paper deals with the Fuzzy Hybrid Flow Shop (FHFS) scheduling inspired by a real apparel process. A Parallel Greedy (PG) algorithm is proposed to solve the FHFS problems with Setup Time (ST) and Lot Size (LS).

Mathematics in the context of fuzzy sets: basic ideas, concepts, and some remarks on the history and recent trends of development

open access: yesMathematical Modelling and Analysis, 2011
The main aim of this paper is to discuss the basic ideas and concepts of the so called ‘Fuzzy Mathematics’ and to give a brief survey of the history and of some trends in recent development of mathematics and its applications in the context of fuzzy sets.

Prioritised fuzzy constraint satisfaction problems: axioms, instantiation and validation [PDF]

open access: yes, 2003
This paper identifies a generic axiom framework for prioritised fuzzy constraint satisfaction problems (PFCSPs), and proposes methods to instantiate it (i.e., to construct specific schemes which obey the generic axiom framework).

Approach to solve multi-criteria group decision-making problems by exponential operational law in generalised spherical fuzzy environment

open access: yesCAAI Transactions on Intelligence Technology, 2020
The construction of generalised spherical fuzzy number (GSFN) is a reliable philosophy to design and understanding of vagueness and impreciseness. In this study, at first, the authors have defined the generalised spherical fuzzy set and discussed its ...

Gauss-Seidel and Sor Methods for Solving Intuitionistic Fuzzy System of Linear Equations

open access: yesComputer Sciences & Mathematics Forum, 2023
Solving various real-life problems ultimately requires solving systems of linear equations. However, the parameters involved in such real-life problems may be pervaded with uncertainty, which results in fuzzy parameters rather than crisp parameters ...

FUZZY NUMBERS IN VALUATION OF REAL INVESTMENT PROFITABILITY [PDF]

open access: yesFinancial Internet Quarterly
In response to the weakness of traditional efficiency assessment methods taking risk into account, the modification of the Certainty Equivalent method is proposed in this paper. The possibility of connecting solutions from different fields provides for the elaboration of a more effective tool to illustrate and indicate the accurate level of risk in the
