基于WBS-RBS与组合权重的装配式建筑施工HSE风险评价

为了准确评价装配式建筑在施工过程中的风险等级,以"健康、安全和环境(HSE)"作为准则层,收集和分析了装配式建筑在施工过程中可能存在的风险因素,构建了施工风险评价指标体系;基于作业分解结构-风险分解结构(WBS-RBS)对项目进行分解,利用层次分析法和熵权法对指标进行组合赋权;通过计算各作业单元综合权重和风险度确定风险...

HSE Risk Assessment for Prefabricated Building Based onWBS-RBS and Combined Weight

To accurately evaluate the risk level of prefabricated buildings during the construction process， taking "health， safety, andenvironment（ HSE） " as the criterion layer， the potential risk factors during the construction process of prefabricated buildings werecollected and analyzed， and a construction risk evaluation index system was constructed. The project was decomposed based on workbreakdown structure-risk breakdown structure（ WBS-RBS）， and the risk indexes were weighted by analytic hierarchy process andentropy weight method. Finally， by calculating the comprehensive weight and the risk degree of each operation unit to determine therisk level， Lanzhou city was taken as an example to verify it. The results show that the construction risk level of the componentinstallation stage of model residential district project is 7.514， belonging to the medium risk， and the evaluation results are basicallyconsistent with the actual project.
