水电工程高危作业安全管理风险评价

Fuzzy comprehensive assessment on safety management of high-risk construction in hydroelectric project

为准确评价水电工程高危作业安全管理风险,提出基于层次分析法(AHP)-熵权法(Entropy)的安全管理风险模糊综合评价法。在前人研究和调查反馈的基础上,结合水电工程高危作业安全管理特点,构建了水电工程高危作业安全管理风险评价指标体系;通过AHP与Entropy算出综合权重,再运用模糊综合评价法计算综合评价得分,预测风险等级,为项目决策者提供依据。运用该方法对某个水电工程的高危作业进行了分析,结果显示其安全管理风险介于一般和较好之间,更接近于一般,说明该项目存在较大的风险隐患。研究表明该方法具有可行性和有效性,可为水电工程高危作业风险控制提供有益的理论支撑。

In order to accurately assess the safety management risks in high-risk constructions of hydroelectric project,fuzzy comprehensive assessment method based on AHP-Entropy is put forward. According to the previous studies and investigation feedbacks,and combining the characteristics of safety management in the high-risk constructions of hydroelectric project,an assessment index system is constructed. After the weights calculation by AHP-Entropy method,the comprehensive assessment scores are obtained using fuzzy comprehensive assessment method to predict the level of riskiness for providing reference for the decision-makers. The method is applied to analyze the high-risk constructions in a hydropower project,and the results show that its safety management is rather mediocre,indicating the project is exposed to high risk level. The fuzzy comprehensive assessment method is proved to be feasible and effective.
