| Summary: | 碩士 === 國立高雄科技大學 === 工業工程與管理系 === 107 === In the process of decision making, decision makers express opinions through preference relationships, but decision makers may not be able to accurately give preference to alternatives, therefore must verify consistency. We verify the additive consistency and multiplicative consistency of fuzzy preference relations, interval fuzzy preference relations and intuitionistic fuzzy preference relations through existing models, and found out the rules that meet the consistency preference value when there are three alternatives, we also provide code using Mathematica software. Finally, compare the differences of three preference relationships under different consistency conditions, The analysis results show that the fuzzy preference relationship and the other two preference relationships may be the same or different in the priority weight and the program ranking, while the interval fuzzy preference relationship and the intuitionistic fuzzy preference relationship are the same.
