Characterization of the Ranking Indices of Triangular Fuzzy Numbers
2014We find necessary and sufficient conditions for a ranking index defined on the set of triangular fuzzy numbers as a linear combination of its components to rank effectively. Then, based on this result, we characterize the class of ranking indices which generates orderings on triangular fuzzy numbers satisfying the basic requirements by Wang and Kerre ...

PROJECT CHARACTERISTICS WITH TRIANGULAR FUZZY NUMBER
2023The Critical Path Method (CPM) is required to plan, organize, and arrange for major project networks. A clear estimate of the time duration will help in the successful execution of the CPM. However, the time duration cannot be precisely specified in real life.

Ranking Triangular Fuzzy Numbers Using Fuzzy Set Inclusion Index
2013In this paper, an original ranking operator is introduced for Triangular Fuzzy Numbers. The purpose is to elaborate fast and efficient algorithms dealing with complicated operations and big data in fuzzy decision-making. The proposed ranking operator takes advantage of the topological relationship of two triangles, besides the Inclusion Index concept —

New Pareto Approach for Ranking Triangular Fuzzy Numbers
2014Ranking fuzzy numbers is an important aspect in dealing with fuzzy optimization problems in many areas. Although so far, many fuzzy ranking methods have been discussed. This paper proposes a new Pareto approach over triangular fuzzy numbers. The approach is composed of two dominance stages.

Hermite Interpolation with Triangular Fuzzy Numbers
International Journal of Fuzzy Mathematical Archive, 2017In this paper the polynomial interpolation of triangular fuzzy number is discussed. First general form of the polynomial with fuzzy coefficients is proposed. The hermite interpolation method is studied with triangular fuzzy number an example is provided to illustrate the algorithm.

A Fuzzy C-means Type Clustering Algorithm on Triangular Fuzzy Numbers
2009 Sixth International Conference on Fuzzy Systems and Knowledge Discovery, 2009Fuzzy number type data is a typical class of fuzzy data, and it can be regarded as a general form of the interval data and the crisp data. This paper studies fuzzy clustering algorithm for triangular fuzzy numbers. First of all, we give a novel distance between triangular fuzzy numbers by using three parameters interval number, and prove that the ...

Fully fuzzy linear systems of triangular fuzzy numbers (a,b,c)
International Journal of Intelligent Computing and Cybernetics, 2013PurposeThe purpose of this paper is to study a nascent theory and an emerging concept of solving a fully fuzzy linear system (FFLS) with no non negative restrictions on the triangular fuzzy numbers chosen as parameters. Two new simplified computational methods are proposed to solve a FFLS without any sign restrictions.

Brief note on distributivity of triangular fuzzy numbers
Kybernetika, 1995Summary: The general results summarized by \textit{D. Dubois} and \textit{H. Prade} [``Fuzzy numbers: An overview'', in: J. C. Bezdek (ed.), Analysis of fuzzy information, Vol. 1, Math. logic, 3-39 (1987)] and the author [Int. J. Gen. Syst. 20, No. 1, 59-65 (1991; Zbl 0739.90074)] show that fuzzy quantities and more especially fuzzy numbers do not ...
