| 摘 要： | 从图论的角度,研究粗糙集模型及决策表相对正域和决策规则.方法：将关系和集合用图表示,通过求图的子图以及两图是否相交来求解集合上、下近似；通过求带权图的子图求取决策表相对正域,以及决策规则.基于图论的粗糙集模型更形象更直观.本文提供了一个研究粗糙集模型的新方法.

| Abstract: | Purpose - From the view of graphics,this paper studies Rough set and decision table relative posi-tive region and decision rule. Methodology/approach - it explores the relation and set with graphics, through seeking the subgraphics of graphics and whether two graphics is intersection to resolve set lower approximation, upper approximation; by seeking the subgraphics of weighted graphics, to solve decision table relative positive region, and the decision nile. Result - Rough Set based on Graphics is much more visual and intuitionistic. Conclusion - this paper provides a new method of studying Rough set and decision table. |
