    Correlation coefficients of interval-valued intuitionistic hesitant fuzzy sets and their application to clustering analysis
    (UMT Lahore, 2019-07-15) ADINA ASIM
    In this study, we inspect the group decision making uncertainties present in interval-valued intuitionistic hesitant fuzzy sets. Firstly, we extended the correlation coefficient formulas of intuitionistic hesitant fuzzy sets to interval-valued intuitionistic hesitant sets, to pile up the interval-valued intuitionistic hesitant fuzzy set values. Then, these values are represented in the form of a decision matrix. After which, we have performed the composition of a matrix to establish the given data within the several clusters. Then grade the choices in line according to the correlation coefficients between interval-valued intuitionistic hesitant fuzzy values and choose the most desirable one. Finally, two real world examples are utilized to elaborate the necessity of the presented approach.
