针对影响公路建设施工现场安全的因素具有模糊、不确定性的特点,综合模糊综合分析方法与集对分析方法的优点,提出了基于模糊-集对分析的评价模型。根据公路施工的特点,构建了公路施工现场安全评价指标体系,应用层次分析法确定了各评价指标的权重,计算了集对联系度,得出了参评公路施工现场安全状况发展趋势与不确定性排序。研究结果表明:该模型能够同时考虑安全评价中信息的确定性与不确定性,用于公路施工现场的安全评价能够得到较好的评价结果。
According to the characteristics of fuzzy and uncertainty in the factors that affect the safety of highway construction site, this paper puts forward the evaluation model based on fuzzy-set pair analysis combining the advantages of fuzzy comprehensive analysis and set pair analysis. According to the characteristics of highway construction, the highway construction site safety evaluation index system is established. The analytic hierarchy process is adopted to determine the weight of each evaluation index. The set-pair connection degree is calculated. The development trend and uncertainty of the highway construction site safety status are obtained Sort. The results show that the model can consider the certainty and uncertainty of the information in the safety evaluation at the same time, and can be used to evaluate the safety evaluation of the highway construction site well.
