摘要
为了加强对建筑安全事故历史案例经验的利用,提高建筑安全事故应急管理的信息化水平,对如何利用智能化技术制定事故应急措施进行研究。将规则推理引入案例推理中,建立了建筑安全事故应急措施推理模型。通过计算综合相似度,在案例库中检索出相似案例的基础上,根据关键属性运用规则推理对相似案例的应急措施进行适用性修改。计算特征属性权重时,利用灰色关联分析法对传统粗糙集方法进行改进,对冗余属性提出了灰色重要度的概念,避免了冗余属性权重为0的情况。选取基坑事故案例对模型进行实例分析,结果表明:建筑安全事故应急措施推理模型具有普遍适用性,可应用于事故应急管理。
In order to strengthen the utilization of historical case experience about construction safety accidents and improve the informatization level of emergency management on construction safety accidents,the research on how to use intelligent technology to develop accident emergency measures was carried out. The rule- based reasoning was introduced into case-based reasoning,and a reasoning model on emergency measures of construction safety accident was established. Based on retrieving the similar cases in case library by calculating the comprehensive similarity,the emergency measures of similar cases were modified for applicability by using rule- based reasoning according to the key attributes. In the calculation of weights for characteristic attributes,the traditional rough set method was improved by using grey relational analysis method,and the concept of grey importance was proposed for redundant attributes,which avoids the situation that the weight of redundant attribute is 0. The case study was conducted on the model by selecting a case of foundation pit accident,and the results showed that the reasoning model on emergency measures of construction safety accident has universal applicability,and it can be widely popularized in the field of emergency management on safety accidents.
