摘要
针对模糊环境下的多属性决策中属性权重信息未知且属性值是区间数的情况,利用粗糙集理论将区间数排序问题转化为实数域上的排序问题,得到基于变精度粗糙集的一种新的区间数排序方法.
Aimed at the fuzzy condition in multiple attribute decision-making which attribute weight information is unknown and the attribute value is interval number, makes use of rough sets theory to change the problem of interval number ranking into the problem of real number region ranking. Obtains a new interval number ranking method based on variable precision rough set.
