Achieving consensus in interval valued intuitionistic fuzzy environment

In this work we combine classical distance metrics (Hamming and Euclidean), interval valued intuitionistic aggregation operators and different starting points to achieve consensus in a group decision making situation. Optimality is achieved by minimizing weighed incoherencies between each opinion, described by interval valued intuitionistic fuzzy sets (IVIFS), and the consensus in an iterative scheme. An example illustrating the different...
