摘要
介绍了向量间的投影,并分别针对三角模糊数序列、区间数和三角模糊数混合序列提出了其投影算子,并证明了投影算子满足线性变换性质,为不同数值类型无法排序的问题提供了解决办法。实例表明了其实际性和可行性。
This paper introduces projection for vector,and discusses the problem of index sequences of triangle fuzzy numbers,including both interval numbers and triangle fuzzy numbers respectively.Based on the optimal sequence,the ranking of alternatives can be expressed by projection values,and the linear characteristics of projection are proved.This method solves the ranking problems of sequences containing different number types.And the method's practicality and feasibility is proved by example.
