针对当前建筑施工现场安全管理存在的问题,通过对施工现场的风险源的辨识,构建基于现场物和施工人员的建筑施工风险评价指标体系,通过改进的层次分析法结合模糊综合评价,即网络层次分析-模糊综合评价(ANP-FUZZY)实时评价施工现场施工状态的安全状态,并设计出了一套基于物联网的建筑现场施工风险因素智能监测系统.施工现场ANP-FUZZY风险评价模型改善了传统关联分析中主观性强的缺陷,使评价结果更具客观性和科学性; 以施工现场脚手架为例,在施工现场30组小样本实验中,ANP-FUZZY算法风险识别率100%,状态误判率7%,而在60组小样本实验中,风险识别率为100%,状态误判率降低至1.7%,验证了建筑施工风险评价模型的可行性和准确性.
Aiming at the problems existing in the construction site safety management for construction, the construction site risk source is identified. Based on scaffolding and construction personnel of construction risk evaluation index system, are improved analytic hierarchy process(AHP)is combined with FUZZY comprehensive evaluation. The network hierarchy analysis and FUZZY comprehensive evaluation(ANP - FUZZY)real-time evaluation of construction site construction safety state is carriedout, and a set of construction site construction risk factors are defined based on Internet of things intelligent monitoring system. The construction site ANP-FUZZY risk evaluation model can improve the defects of strong subjectivity in the traditional correlation analysis and make the evaluation results more objective and scientific. Take scaffolding as an example, in 30 groups of small sample experiments on the construction site, the scaffold risk identification rate of ANP-Fuzzy algorithm is 100% and the state misjudgment rate is 7%, while in 60 groups of small sample experiments, the scaffold risk identification rate is 100% and the state misjudgment rate is reduced to 1.7%, which verifies the feasibility and accuracy of the construction risk evaluation model.
