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

Power series of fuzzy numbers with real or fuzzy coefficients

open access: yesFilomat, 2012
Following Talo and Ba?ar [Determination of the duals of classical sets of sequences of fuzzy numbers and related matrix transformations, Comput. Math. Appl. 58 (2009) 717-733], we essentially deal with the power series of fuzzy numbers. We give two examples on the geometric series of fuzzy numbers and by using the four different cases of ...

A new model for solving fuzzy linear fractional programming problem with ranking function

open access: yesJournal of Applied Research on Industrial Engineering, 2017
In this paper, we studied fuzzy linear fractional programming (FLFP) problems with trapezoidal fuzzy numbers where the objective functions are fuzzy numbers and the constraints are real numbers.

Ranking fuzzy numbers by volume of solid of revolution of membership function about axis of support [PDF]

open access: yesDecision Science Letters, 2023
It is admissible that fuzzy numbers (FNs) are apt for representing imprecise or vague data in real-world problems. While using FNs in decision-making problems, selecting the best alternative among available alternatives is challenging, and ...

A Novel Definition of Fuzzy Difference on Non-increasing Fuzzy Real Numbers

open access: yesJournal of Physics: Conference Series, 2023
Abstract In this paper, firstly, a novel definition of a fuzzy difference based on non-increasing fuzzy real numbers is introduced, which is different from the previous definitions by using fuzzy interval-numbers and Zadeh’s extension principle.

A Direct Method to Compare Bipolar LR Fuzzy Numbers

open access: yesAdvances in Fuzzy Systems, 2018
We propose a new method for ordering bipolar fuzzy numbers. In this method, for comparison of bipolar LR fuzzy numbers, we use an extension of Kerre’s method being used in ordering of unipolar fuzzy numbers.

Best proximation of fuzzy real numbers

open access: yesJournal of Fuzzy Set Valued Analysis, 2014
Fuzzy appear as the most popular family of fuzzy sets useful both for theoretical considerations as well as diverse practical applications. In this note we show that the set of fuzzy numbers is a closed and convex set of $L^p$, and therefore is a Chebyshev set.

An additive decomposition of fuzzy numbers [PDF]

open access: yes, 2003
summary:Hong and Do[4] improved Mareš[7] result about additive decomposition of fuzzy quantities concerning an equivalence relation. But there still exists an open question which is the limitation to fuzzy quantities on R (the set of real numbers) with ...

An approach to multiple attribute group decision making with interval intuitionistic trapezoidal fuzzy information

open access: yesTechnological and Economic Development of Economy, 2012
In this paper, we investigate the multiple attribute group decision making (MAGDM) problems in which both the attribute weights and the expert weights take the form of real numbers, attribute values take the form of interval intuitionistic trapezoidal ...

A Novel Approach to Solve Fully Fuzzy Linear Programming Problems with Modified Triangular Fuzzy Numbers

open access: yesMathematics, 2021
Recently, new methods have been recommended to solve fully fuzzy linear programming (FFLP) issues. Likewise, the present study examines a new approach to solve FFLP issues through fuzzy decision parameters and variables using triangular fuzzy numbers ...
