基于理想点的三角模糊数多指标决策法

Method for triangular fuzzy number multiple attribute decision making based on ideal solution

研究了属性权重和属性值均以三角模糊数形式给出的模糊多指标决策问题,定义了三角模糊数正理想方案和负理想方案,由此给出了三角模糊数多指标决策问题的理想点法。该方法简单实用,所需信息小.最后用该方法分析了一个实际问题。

The fuzzy multi-attribute decision-making problem that the attribute weights and the attribute values are both in the forms of triangular fuzzy numbers is studied. The positive ideal scheme and negative ideal scheme for triangular fuzzy numbers are defined. A method based on ideal solution to fuzzy multi-attribute decision-making problem of triangular fuzzy numbers is presented. This method is simple, practical and demands less information. Finally, a concrete problem method is analyzed with this.
