应用于化工事故推理的案例库系统

The System of Case Database for Chemical Accident Reasoning

针对化工事故的推理,开发了化工事故案例库系统,为HAZOP等依赖人工推理的方法提供可靠性依据。介绍了应用于化工事故推理的案例库的系统结构、案例表达方法以及案例库的检索系统设计。其中,案例属性的表达是依据对化工事故的分类思想,案例检索采用了局部属性与全局属性相结合的方法,并着重研究了数字属性和语义属性的匹配以及相似度的算法。实际案例的应用结果表明本系统有效地提高了事故推理的自动化程度,具有很高的实际意义。

Aiming at chemical accident reasoning, a system of case database for chemical accident reasoning is developed, which provides reliable basis for HAZOP depending on artificial reasoning. This paper briefly introduces the frame of the system, the representation of accident property and the design of the search system. The representation of accident property is based on classifying thought. The matching algorithm and similarity measurement of numerical and semantic properties are emphatically studied. The practical case study demonstrates that this system of case database for chemical accident reasoning improves the level of automation in accident reasoning with high practical significance.
