A New Ranking on Hexagonal Fuzzy Numbers

A New Ranking on Hexagonal Fuzzy Numbers

The objective of this paper is to introduce a fuzzy linear programming problem with hexagonal fuzzy numbers. Here the parameters are hexagonal fuzzy numbers and Simplex method is used to arrive an optimal solution by a new method compared to the earlier existing method. This procedure is illustrated with numerical example. This will further help the decision makers to come out with a feasible a...

FUZZY RISK ANALYSIS BASED ON A NEW METHOD FOR RANKING GENERALIZED FUZZY NUMBERS

Fuzzy risk analysis, as a powerful tool to address uncertain information, can provide an appropriate method for risk analysis. However, the previous fuzzy risk analysis methods still have some weaknesses. To overcome the weaknesses of existing fuzzy risk analysis methods, a novel method for ranking generalized fuzzy numbers is proposed for addressing fuzzy risk analysis problems. In the propose...

A new approach for ranking fuzzy numbers

In this paper, we propose a novel approach for constructing a preference fuzzy distance measure. For this purpose, we propose a new and effective preference ordering based on the Abbasbandy and Hajjari’s approach [2].

A new parametric method for ranking fuzzy numbers based on positive and negative ideal solutions

Extend a ranking method of trapezoidal fuzzy numbers to all fuzzy numbers by a weighting functions

Recently Abbasbandy and Hajjari (Computers and Mathematics with Applications57 (2009) 413-419) have introduced a ranking method for the trapezoidalfuzzy numbers. This paper extends theirs method to all fuzzy numbers,which uses from a defuzzication of fuzzy numbers and a general weightingfunction. Extended method is interesting for ranking all fuzzy numbers, and itcan be applied for solving and ...
