一种基于差异度变权的多属性决策方法

A Multi-attribute Decision Method Based on Deviation Degree Variable Weights

针对属性权重信息完全未知的多属性决策问题,通过引入属性值的差异度、基于差异度的变权等概念,提出了基于差异度变权的多属性决策方法.利用差异度客观地确定了属性的权重,并以此为常权,借助状态变权,实现了属性值之间的均衡.最后通过具体实例,说明该决策方法的可行性和有效性.

The multi-attribute decision which information on attribute weights is unknown completely,we define the deviation degree of the attribute values.And then we propose a multi-attribute dicision method based on it.The proposed method can determine the weights of attributes objectively.Based on deviation degree,we utility the state weights vector,realize the balance of the attribute values.Finally,an example is given to illustrate the feasibility and effectiveness of the method.
