摘要
为了解决多属性决策问题,采用三角模糊数的三角函数表达式进行多属性决策,从概率统计的角度提出均值与方差也是三角模糊数特征参数,用二元联系数表示三角模糊数的特征参数,并映射到D—u空间。不仅结果可信,而且能直观地看出三角模糊数不确定性对方案排序稳定性的影响。
In order to solve the problem associated with multipal attributes decision making,the trigonometry function with triangular fuzzy number is used for multiple attributes decision making. The mean and variance are also considered as the parameters for triangular fuzzy function based on statististical probability theory. The binary connection number is used to describe the the feature parameter of triangular fuzzy number and map it into the D-u space. The result is valid and useful for the direct obersvation on the impact of uncertainty of triangular fuzzy number on the stability of plan permutation.
