On Aggregating uncertain information by Type-2 OWA operators for soft decision making.
(John Wiley and Sons, 2010)
A Statistical Comparative Study of Different Similarity Measures of Consensus in Group Decision Making
An essential aim in group decision making (GDM) problems is to achieve a high level of consensus among experts. Consensus is defined as general or widespread agreement, and it is usually modelled mathematically via a ...
The Optimization Ordering Model for Intuitionistic Fuzzy Preference Relations with Utility Functions
Intuitionistic fuzzy sets describe information from the three aspects of membership degree, non-membership degree and hesitation degree, which has more practical significance when uncertainty pervades qualitative decision ...
Type-2 defuzzification: Two contrasting approaches.
A social network analysis trust-consensus based approach to group decision-making problems with interval-valued fuzzy reciprocal preference relations
A social network analysis (SNA) trust-consensus based group decision making model with intervalvalued fuzzy reciprocal preference relation (IFRPR) is investigated. The main novelty of this model is that it determines the ...
The Structure of the Type-Reduced Set of a Continuous Type-2 Fuzzy Set
(Atlantis Press, 2013-08)
This paper is concerned with the structure of the type-reduced set (TRS) of the continuous type-2 fuzzy set, in both its interval and generalised forms. In each case the TRS structure is approached by first investigating ...
Challenges and Open Questions in Soft Consensus Models
In group decision making problems, given the importance of obtaining an accepted solution by the whole group, the consensus has attained a great attention and it is virtually a major goal of these problems. Consensus, as ...
Fuzzy in 3-D: Contrasting Complex Fuzzy Sets with Type-2 Fuzzy Sets
Complex fuzzy sets come in two forms, the standard form, postulated in 2002 by Ramot et al., and the 2011 innovation of pure complex fuzzy sets, proposed by Tamir et al.. In this paper we compare and contrast both forms ...
