摘要
以粗糙集理论为基础,设计了专家系统的知识获取和知识过滤模块,构建了围岩稳定性评价专家系统。运用粗糙集理论的数据挖掘技术,对数据进行分析,从实测的数据中删去大量对决策无效的冗余数据,实现了对知识库的精简,形成了决策规则。解决了专家系统开发过程中的知识获取、知识处理和知识运用的核心难题。将基于粗糙集理论的专家系统应用于围岩稳定性评价,为围岩稳定性评价提供了一种新方法。
The knowledge acquisition and knowledge filter module of the expert system is designed, and the surrounding rock evaluating expert system is also established based on the rough set theory. Rough set theory is a data mining approach that deals with vagueness and can be used to discover hidden decision rules from vast amount of monitoring data. It provides a new method to evaluate the stability of surrounding rock with rough set applied to expert system.
