摘要
在乐观的多覆盖模糊粗糙集的基础上,建立了悲观的多覆盖模糊粗糙集模型.分别讨论了悲观多覆盖模糊粗糙集、基于交的覆盖模糊粗糙集、覆盖模糊粗糙集和乐观多覆盖模糊粗糙集之间的关系.该模型的建立和得到的诸多性质丰富了粗糙集理论.
In this article, based on the optimistic multi-covering fuzzy rough sets, the model of pessimistic multi-covering fuzzy rough sets is developed.Furthermore, relationships among optimistic multi-covering fuzzy rough sets, covering fuzzy rough sets based on intersection,covering fuzzy rough sets and pessimistic multi-covering fuzzy rough sets have been studied.All of these results enrich the fuzzy rough set theory.
