| 摘 要： | 安全评价与隐患处理是铁路行车安全管理工作的重点。针对安全信息的多源、模糊特性,基于Vague集理论建立安全评价信息提取模型;为实现安全隐患信息数据库的知识提取,运用粗糙集方法提取安全隐患的特征规则,并对安全隐患信息数据库进行高效约简。算例表明,安全评价信息提取模型能够对行车安全状况进行合理评价,安全隐患信息提取方法能够高效提取隐患的特征规则。该方法可用于铁路行车安全评价与安全信息提取,为铁路行车安全管理工作提供决策支持。

| Abstract: | Safety evaluation and hidden danger treatment are the key points of management of railway service safety.In view of the multi-source and fuzzy characteristics of safety information,the safety evaluation information extraction model was built by the Vague set theory.In order to extract mass data of safety hidden danger information,the feature rules of safety hidden danger information were extracted by the rough set theory and the historical database reduction was realized effectively.Case study proves that t... |
