摘要
介绍了粗糙集理论的基本原理及粗集不协调率的概念、计算公式及其意义 ,指出应用粗糙集不协调率可以精确地进行敏感度分析 ,并对影响地下硐室稳定性的诸多因素进行敏感度分析 ,并取得了明显的效果 ,从而为诸多因素进行比较、权衡轻重又开辟了一条新的途径 。
Introducing the viewpoint of Classfication and Approach of Rough Sets,putting forward the conception of non?correspond ratio and the calculation expression,analyzing the sensitivity of the affecting factors in underground grottos through using the non?correspond ratio of rough sets,and finding the main factors, which represent and simplify knowledge as a tool in Decison Support System(DSS).
