施工安全教育培训关键管理因素分析

Analysis of Key Management Factors of Construction Safety Education and Training

采用模糊故障树分析方法,构建施工安全教育培训系统的故障树模型。采用上行法求解故障树顶事件的最小割集,利用德尔菲法结合模糊集理论合理确定底事件发生概率,计算得到故障树顶事件发生概率和底事件的关键重要度。结合各底事件在实际施工中的发生频率,找出系统中的关键管理因素,并提出相应的改进措施。

This paper uses fuzzy fault tree analysis method to build a fault tree model for construction safety education and training system.Then,uses the ascending method to find minimum cut sets of top events and reasonably determines the occurrence rate of bottom events with Delphi method and fuzzy theory.Finally,calculates the occurrence rate of the top events and the critical importance of the bottom events in fault tree,identifies key management factors combined with the actual occurrence frequency of each bottom event,and proposes the corresponding improvement measures.
