基于信息挖掘的相对优势度的直觉模糊数排序

摘要

考虑到两数在不同的待排序数组中的大小比较程度是不同的，通过挖掘待排序数所蕴含的信息，给出一种新的区间数优势度定义、得出其相应性质，然后把区间数相对优势度的定义推广到直觉模糊数，并在此基础上对直觉模糊数进行排序，提高了最后评价的客观性和合理性。%Given that two numbers in different ranking groups are different in comparing degree, firstly, the paper mines some information from ranking numbers, gives a new definition of relative superiority describing big or small interval number. And, the properties from the definition are studied. Then, the definition of relative superi-ority of interval numbers was extended to intuitionistic fuzzy numbers. On the basis of this, the paper gives a meth-od for ranking intuitionistic fuzzy numbers. By this method, objectivity and rationality on synthetic reviews can be improved.
