基于模糊-集对分析模型的公路建设施工安全评价研究

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。

Research on Highway Construction Safety Evaluation Based on Fuzzy-Set Pair Analysis Model

In the light of factors influencing highway construction safety has characteristics of fuzziness and uncertainty,an evaluation model based on fuzzy-set pair analysis is put forward,which combines advantages of fuzzy comprehensive analysis method and set pair analysis method.According to characteristics of highway construction,the construction safety evaluation index system is constructed,the weight of each index is determined by Analytic Hierarchy Process(AHP)and connection degree is calculated,so the safety condition development and uncertainty rank of evaluated highway construction sites are calculated.It is shown that the model can deal with certainty and uncertainty of information in safety evaluation at the same time,thus good results can be reached through application of the model.
