区间型多属性决策的一种新方法

New method for interval multi-attribute decision-making

定义了区间型理想点以及决策方案在区间型理想点上的投影等概念 .对于属性值以区间数形式给出的区间型多属性决策问题 ,提出了一种新的决策方法 .该法无需对区间数进行比较和排序 ,具有简洁、直观、易于计算等特点 .

The concepts of interval ideal point and projection of each alternative on the interval ideal point, etc., are defined. A new method is proposed for interval multi-attribute decision-making, in which the attribute values are in the form of interval numbers. The method can avoid comparing and ranking interval numbers. It is straightforward and can be performed on computer easily. Finally, an illustrative example is given to demonstrate the feasibility and practicability of the proposed method.
