Multicriteria Fuzzy Decision Making Method by Using Approximate Reasoning Based on Vague Set
基于Vague集模糊推理的多评价指标模糊决策方法

At present in the area of intelligence it is more and more widely and deeply to research Vague set. Vague set is being used into decision making. Some scholars have researched multicriteria fuzzy decision making methods by using Vague set theory.But the result does not be gotten by them in some conditions. Hence, we propose a multicriteria fuzzy decision making method by using approximate reasoning based on vague set. The fuzzy decision making is treated in the view of approximate reasoning based on vague set. The relation between multicriteria and alternative are represented to a group of reasoning rules, requirements of decision maker are represented to a vague set. Through approximate reasoning and some other procedures we can get best choice from the alternatives. And then an example is also presented to illustrate the application of the proposed multicriteria fuzzy decision making method by using approximate reasoning based on vague set. This multicriteria fuzzy decision making method by using approximate reasoning based on vague set provides a useful tool for multicriteria fuzzy decision making system.
