摘要
定义了正态分布的区间粗糙数,补充联系数的运算法则。利用集对分析的不确定性理论,建立了区间粗糙数的均值-方差联系数模型,针对属性值为区间粗糙数且权重已知的区间粗糙数多属性决策问题,提出了一种基于联系数的区间粗糙数多属性决策方法,并给出了决策的步骤。最后,通过实例分析,表明该方法的有效性和实用性,且计算简单易行。
The definition of interval rough number,obeying the normal distribution,is given and the connection numberalgorithms are added.A connection number model is transformated by establishing interval rough number mean-varianceand using the uncertainty theory of the set pair analysis.For the attribute values are interval rough number and attributeweights are known,a multiple attribute decision making method based on connection number is proposed.Then the decision-making steps are given.Finally,a numerical example is given to show this approach is effective,practical and simple.
