摘要
针对客观世界中的不确定性知识,利用模糊元素迁移的概念,将静态的区间值模糊集推广到动态的情形,得到了S-区间值模糊集.并在此基础上提出了双向S-区间值模糊集,讨论了其相关性质.
In the light of uncertain knowledge in people＇s life,using the concept of fuzzy elementary transfers,a static interval-valued fuzzy set was generalized to a dynamic interval-valued fuzzy sets,then a two-direction S-interval-valued fuzzy set.Based on this,a two-direction S-rough interval-valued fuzzy set was put forward,and the properties of a two-direction S-rough interval-valued fuzzy set was proposed.
