摘要
近年来 ,人们提出许多描述不确定性的方法。本文将给出粗糙集和模糊集的比较。粗糙集理论是描述模糊性和不确定性的一种新的数学工具。由于大家对模糊集的熟悉 。
Many different ways of reasoning about uncertainty have been developed in recent years. In this paper, we review two of these theories: Rough Sets, Fuzzy Sets. The Rough Set theory is a new mathematical tool to reason about vagueness and uncertainty. Because we are all familiar with Fuzzy Sets, we will not give the concept of Fuzzy Sets in this paper.
