【摘要】：为有效控制起重机械安全事故的风险,提出基于粗糙集的起重机械安全风险评价方法。本文在芜湖长江公路二桥主桥项目现场调研基础上,通过文献研究、起重机械安全事故案例总结、专家访谈等研究方法,从机械、人、环境三个方面,构建出一套反映该项目各类起重机械整体安全隐患和安全状态的风险评价指标体系。运用粗糙集理论对风险评价指标进行属性约简删除冗余指标,并对风险评价指标的权重值进行计算,有效地避免了主观确定指标权重的问题,客观地反映出各个风险因素对起重机械安全的影响程度,为工作人员风险决策提供参考依据。最后结果表明该项目人和机械这两大风险因素权重所占的比重较大,在起重机械的安全管理中应加强对这两个方面的风险控制。
[Abstract]:In order to effectively control the risk of crane safety accidents, a rough set based risk assessment method for crane safety is proposed. Based on the field investigation of the main bridge project of Wuhu Yangtze River Highway Bridge, this paper makes a literature study. Crane safety accident case summary, expert interviews and other research methods, from the machinery, human, environmental three aspects. Set up a set of risk evaluation index system which reflects the whole safety hidden trouble and safety state of all kinds of hoisting machinery in this project, and use rough set theory to reduce the risk evaluation index and delete redundant index. The weight value of the risk evaluation index is calculated, which effectively avoids the subjective problem of determining the index weight, and objectively reflects the impact of various risk factors on the safety of hoisting machinery. The final results show that the weight of the two major risk factors of the project and machinery account for a large proportion. The risk control of these two aspects should be strengthened in the safety management of lifting machinery.
