基于信息量的不确定型多属性决策方法

Information Content Based Method of Uncertain Multi-attribute Decision-making

针对属性值为区间数的不确定型多属性决策问题进行了研究,给出了属性值满意度的概念和考虑风险系数的满意度评价函数计算方法;重定义了公理设计理论的信息量概念,提出了基于信息量的不确定多属性决策方案排序方法,为解决不确定型多属性决策问题提供了一种简单实用的方法。最后利用实例计算了验证了方法的有效性和可行性。

With regard to the uncertain multi-attribute decision-making problems in which attribute values are in the form of interval number,the concept of the satisfactory degree of the attribute value and the satisfactory degree function considering the risk modulus are presented.The concept of the information content is redefined and the ranking method based on the information content of alternatives is presented,which is a simple and pragmatic method to resolve much uncertain multi-attribute decision-making problems.Finally,an example is presented to confirm the validity and the feasibility of the method.
