Q-rung orthopair fuzzy sets and their some aggregation operators

This thesis consists of seven sections. In Section 1, detailed literature review and aim of the thesis are explained. In Section 2, definitions of fuzzy set, intuitionistic fuzzy set, Pythagorean fuzzy set and q-rung orthopair fuzzy sets, and operations between the q-rung orthopair fuzzy numbers are presented with their examples. In Section 3, definitions of q-Rung orthopair fuzzy weighted averaging and weighted geometric operators and their properties are presented. Also, for every formula and properties, examples are given. In Section 4, q-rung orthopair fuzzy Bonferroni mean and q-rung orthopair weighted Bonferroni mean operators are given and their properties are presented with their examples. In Section 5, q-rung orthopair fuzzy Heronian mean and q-rung orthopair weighted Heronian mean operators are given and their properties are presented with their examples. In Section 6, q-rung orthopair fuzzy Maclaurin symmetric mean and q-rung orthopair weighted Maclaurin symmetric mean operators are given and their properties are presented with their examples. In Section 7, some explanations are made about the results of the thesis.
