Multi-Attribute Group Decision Making Using Fuzzy Numbers at Arithmetic Intervals for Determining Thesis Examination

In general, thesis examiners have opposing viewpoints. Despite the fact that the assessment parameters are the same, each examiner can provide a different standard of evaluation. Group decision making can be used to solve problems in the assessment of thesis exams involving a large number of examiners. Group decision making can be used to solve problems in the assessment of thesis exams involving a large number of examiners. In the group's decision-making process, this paper provided fuzzy numbers at the arithmetic interval. Decisions that generally give a vague knowledge of decision-making information and cannot estimate their decision-making information with exact numerical values are used to determine the thesis exam. According to the case study, the fuzzy approach is used to solve the problem, and evaluation alternatives are used to determine the thesis exam. According to the results of the triangular fuzzy approach, the option to repeat the exam (A2) has the highest value and recommended to be a decision.
