基于贝叶斯网络的通用桥式起重机结构安全评价

阐述了通用桥式起重机结构安全评价对于减少起重机事故的重要意义,在对国内外相关研究进行分析和比较的基础上,构建了用于起重机结构安全性评价的指标体系。利用贝叶斯网络所具有的表达不确定性知识和进行不确定性知识推理的能力,提出了基于贝叶斯网络的安全评价模型。该模型能够处理复杂的逻辑关系,很好地表达变量间的不确定性关系,可灵活方便地对系统进行预测及诊断分析,将该方法应用于评估起重机结构的安全等级,以说明其合理性。

Bayesian Network-based general overhead traveling crane structure safety asses sment

Structure safety assessment of general overhead trave li ng crane is necessary for reducing the crane accidents.An index system for stru cture safety assessment is presented according to the related domestic and forei gn studies.In addition,a method for structure safety measurement using Bayesia n network,which has excellent abilities of expressing and reasoning knowledge u nder uncertain environment,is proposed to build the safety assessment model.Th e assessment model is able to deal with complicated rela...
