基于SEM的建筑施工现场安全模糊综合评价研究
首发时间:2016-07-26
摘要:针对建筑施工现场安全评价问题,构建基于结构方程模型(SEM)与模糊综合评价法(FCEM)结合的安全评价模型。首先,设计由人、物、环境和管理四个因素组成的安全评价指标体系。然后,通过发放调查问卷来获取数据,运用结构方程路径分析确定安全评价指标权重,避免了采用人为打分的方法来确定指标权重,降低了评价的主观性。最后,运用模糊综合评价法对实际工程进行安全评价,掌握了整体安全状况并挖掘了隐患存在的原因,同时提出了整改建议。结果表明,用SEM-FCEM模型评价建筑施工现场安全具有可行性和有效性。

Study on safety fuzzy comprehensive evaluation method of building site based on SEM
Abstract:Based on the integration of the SEM and the fuzzy comprehensive evaluation method,this paper puts forward a model to evaluate the safety performance at the construction site.Firstly,designed safety evaluation indexsystem consists of people, goods, environment and management.Then, obtain data through questionnaires,use path analysis of structural equation modeling to determine the safety evaluation index weights,avoid using artificial scoring method to determine the index weight, reduce the subjectivity of evaluation.Finally, usefuzzy comprehensive evaluation method to evaluated safety of building site, grasp the overall security situation and the reasons forhazards exist, and proposed corrective recommendations.The results showed that, SEM-FSEM model used in safety evaluation of building site is feasible and effective.
