| 摘 要： | 多粒度是利用粗糙集方法处理分布式数据的一种有效手段。为了使得多粒度方法能够用于模糊目标的近似逼近,提出了一种多粒度粗糙区间模糊集方法,分别包括乐观和悲观两种不同的模型。不仅对这两种多粒度粗糙区间模糊集的基本性质进行了讨论,而且通过实例分析表明了新提出的模型用于处理区间模糊问题的有效性。

| Abstract: | Multigranulation was an effective approach for dealing with distributed data by rough set. To approximate the fuzzy target by multigranulation approach, a multigranulation rough interval-valued fuzzy approach was proposed, which included optimistic and pessimistic models. Not only the basic properties of such two different multigranulation rough interval-valued fuzzy sets were discussed, but also an illustrative example was analyzed to show the effectiveness of the proposed models. |
