Title Decision Analysis of General Linguistic Interval Valued Intuitionistic Fuzzy Soft Expert Sets

Author(s) Tasaduq Mehmood

Abstract The 2-Dimensional Linguistic Intuitionistic Fuzzy Variables (2-DLIFVs) add a subjective estimation of the trustworthiness of the evaluated results provided by experts, so 2-Dimensional Linguistic Intuitionistic Fuzzy Variables (2-DLIFVs) are very valuable instruments for describing uncertain or fuzzy information. This work extends the notion of 2-DLIVs by introducing General Linguistic Interval-Valued Intuitionistic Fuzzy Soft Expert Sets (GLIVIFSESs) in which the two terms are contained, the first term describes the subjective estimation of the objects under observation or discussions, second term describes the subjective evaluations of the reliability of the valuated results provided by experts. In this thesis we construct few operations on the structure (GLIVIFSESs) and then defines operational laws, scores, and accuracy functions for GLIVIFSESs. We illustrate some examples for the described operations. Further, we progress some arithmetical and geometrical aggregation operators for aggregating GLIVIFSE information and prove so many important properties related with them.
