不相容决策系统中的规则提取方法研究
Research on Rule Extraction Method in Inconsistent Decision System
摘要
Abstract
The current rules extraction methods mostly only extract rules in consistent decision system, and the extracted rules redundant degree is high, it is not easy to understand for users. Aiming at this problem, this paper puts forward a rule extraction method based on cover object set. It divides object set into corresponding equivalence class by using rough set theory, produces effectiveness rules according to the consistency of the similarity degree, and solves inconsistent decision system rules extraction through the equivalence partitioning and object set cover. Numerical example analysis result proves the validity and reliability of the method, and it has good robustness.关键词
