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。
In order to make effective control of the risks of hoisting machinery safety accidents,safety risk evaluation methods of hoisting machinery are proposed on basis of Rough Set Theory. According to site investigation on main bridge project for two bridges of Wuhu Yangtze River Road,the paper constructs one set of risk evaluation index system which can reflect overall potential safety hazards and safety situation of various hoisting machinery from three aspects as machinery, human and environment based on research methods like literature search,cases summary of hoisting machinery safety accidents and expert interviews etc. With Rough Set Theory,it makes attribute reduction and deletes redundant indexes for risk evaluation indicators,calculates weighted value of risk evaluation indicators,efficaciously avoids the problems of index weight determined by subjectivity,objectively mirrors the impact on hoisting machinery safety by various risk factors,and offers reference to risk decision for the staff. Finally,the results show that the weight of two main risk factors as human and machinery of the project occupies more proportion,and it shall strengthen risk control of these two aspects in safety management of hoisting machinery.
