Contrasting Correlation Coefficient with Distance Measure in Interval Valued Intuitionistic Trapezoidal Fuzzy MAGDM Problems

Robinson, John P. - In: International Journal of Fuzzy System Applications (IJFSA) 5 (2016) 4, pp. 16-51

In this paper, Multiple Attribute Group Decision Making (MAGDM) problems in which the data is of the form of Interval Valued Intuitionistic Trapezoidal Fuzzy Numbers (IVITzFNs) is presented. Some operational laws of IVITzFNs are introduced. Then some new aggregation operators including interval...

A GENERALIZED MODEL OF JUDGMENT AND PREFERENCE AGGREGATION

Beg, Ismat; Rashid, Tabasam - In: Fuzzy Economic Review XVIII (2013) 1, pp. 9-27

Some basic notions of fuzzy logic for trapezoidal fuzzy numbers are extended. Purpose of these extensions is to give a generalized model of judgment and preference aggregation by using trapezoidal fuzzy numbers. Examples are given to illustrate the proposed technique to optimize the problem by...

SIGNED DISTANCED-BASED TOPSIS METHOD FOR MULTIPLE CRITERIA DECISION ANALYSIS BASED ON GENERALIZED INTERVAL-VALUED FUZZY NUMBERS

CHEN, TING-YU - In: International Journal of Information Technology & … 10 (2011) 06, pp. 1131-1159

The theory of interval valued fuzzy sets is very valuable for modeling impressions of decision makers. In addition, it gives ability to quantify the ambiguous nature of subjective judgments in an easy way. In this paper, by extending the technique for order preference by similarity to ideal...
