基于案例推理的煤矿应急预案管理系统设计

Design of emergency plan management system of coal mine based on case-based reasoning

针对文本形式的静态预案管理方式对事故发生时救援工作的指导不够精确、难以制定切实可行的救援方案的问题,设计了基于案例推理的煤矿应急预案管理系统。针对实际案例与历史案例的特征属性不匹配问题,提出差异相似度算法,该算法与案例推理中的最近相邻算法结合,能够从预案库中检索出相似度最高的历史案例,从而提高救援方案生成的效率。针对由于案例库不断增大导致查找对应预案变难的问题,给出了分级检索策略。实际应用结果表明,与传统的煤矿应急预案管理方式相比,基于案例推理的煤矿应急预案管理系统更能满足煤矿企业应急救援的及时性和针对性要求。

In view of problem that static plan management method in text-form is not accurate enough to guide rescue work when coal mine accident happened,and it is hard to formulate emergency plan feasibly,a emergency plan management system of coal mine based on case-based reasoning was designed.According to problems of mismatch of feature attribution between actual cases and history cases,differences similarity algorithm was proposed which was combined with nearest neighborhood matching method in case-based reasoning.This algorithm can retrieve the highest similarity historical cases from library plans,and then improve the efficiency of rescue program generating.For the problem that corresponding plan becomes difficult to find since the case base growing,a hierarchical search strategy was presented.The practical application results show that the emergency plan management system of coal mine based on case-based reasoning is better to meet requirements of timeliness and pertinence of coal mine emergency rescue compared with the traditional coal mine emergency plan.
