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 ...

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 ...

On the Fuzzy Convergence

open access: yesJournal of Applied Mathematics, 2011
The aim of this paper is to introduce and study the fuzzy neighborhood, the limit fuzzy number, the convergent fuzzy sequence, the bounded fuzzy sequence, and the Cauchy fuzzy sequence on the base which is adopted by Abdul Hameed (every real number r is ...

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.

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.

Fuzzy Similar Priority Method for Mixed Attributes

open access: yesJournal of Applied Mathematics, 2014
Fuzzy similar priority ratio method is to select the most suitable one to the specific object from feasible alternatives. However, this method considering only the index values of real number has its disadvantages of inaccuracy in result and complexity ...

Ranking efficient DMUs using the Tchebycheff norm with fuzzy data in DEA [PDF]

open access: yesInternational Journal of Research in Industrial Engineering, 2019
In many real applications, the data of production processes cannot be precisely measured. Hence the input and output of Decision Making Units (DMUs) in Data Envelopment Analysis (DEA) may be imprecise or fuzzy-numbered. In original DEA models, inputs and

Project scheduling under uncertainty using fuzzy modelling and solving techniques [PDF]

open access: yes, 2013
In the real world, projects are subject to numerous uncertainties at different levels of planning. Fuzzy project scheduling is one of the approaches that deal with uncertainties in project scheduling problem.

CONSTRUCTION OF THE MEMBERSHIP FUNCTION OF NORMAL FUZZY NUMBERS [PDF]

open access: yesJournal of Process Management and New Technologies, 2013
A fuzzy real number [α, β, γ] is an interval around the real number β with the elements in the interval being partially present. Partial presence of an element in a fuzzy set is defined by the name membership function.

Sequence Spaces of Fuzzy Real Numbers Using Fuzzy Metric

open access: yesKyungpook mathematical journal, 2014
The sequence spaces c F (M ), c F (M ) and l F (M ) of fuzzy real numbers with fuzzy metric are introduced. Some properties of these sequence spaces like solidness, sym- metricity, convergence-free etc. are studied. We obtain some inclusion relations involving these sequence spaces.
