基于AHP-Fuzzy的高处坠落危险性评价研究

高处坠落事故在建筑安全生产事故中所占的比率最大。预防和控制高处坠落事故始终是建筑业应解决的重要问题,高处坠落危险性评价是预防与控制高处坠落事故的重要手段。以高处坠落风险为研究对象,通过对高处作业＂人—机—环境—管理＂复杂系统进行分析,建立生产人员素质因素、生产设备因素、环境条件因素、安全管理因素等4个大类和23个小类的危险性评价指标体系。在层次分析法和模糊综合评价法等研究基础上,构建了高处坠落风险的AHP-Fuzzy评价模型,确定了各层次的权重集。对给出的实例进行评价,评价结果符合实际情况。结果表明,基于AHP-Fuzzy的高处坠落危险性评价方法是可靠与实用的,并对高处坠落危险性的评判有指导意义。

Research and application on risk assessment of high falling based on AHP-Fuzzy

In all the construction accidents,the high falling accident occupied the highest proportion.It had been an important problem for people in construction industry to prevent and control.Risk assessment of high falling accident evolution is an important measure to prevent and control high falling accidents.Based on ＂human-machine-environment-Management＂ complex system,the risk assessment index system about 4 major categories and 23 sub-categories,include the quality of factors of production personnel and the production equipment factors and the environmental conditions factors and the safety management factors were established.The AHP-Fuzzy evaluation model of risk assessment of high falling risk and weight sets were established based on AHP and fuzzy comprehensive evaluation method.The risk assessment example was given and the results were conformed to reality.The results showed that the risk assessment method of high building based on AHP-Fuzzy was reliable and practical,which possesses guiding significance for evaluating the risk of high falling.
