摘要/Abstract

摘要： 为提高装配式建筑施工安全水平,准确判断吊装作业安全状况,建立基于相关向量机(RVM)的预警模型。根据装配式建筑吊装作业特点,对比传统施工模式,分析致使吊装事故发生的主要因素,按人-机-料-法-环(4M1E)5要素确定预警指标体系,并通过粗糙集(RS)属性约简算法确定模型安全预警因子;选用混合核函数构建RVM预警模型,并通过改进粒子群算法(IPSO)寻优确定核参数,给出计算方法及模型流程;以华中地区5个项目的相关数据完成模型学习训练和预警仿真。结果表明:用该模型所得结果与实际情况基本一致,判定正确率为94%、平均相对误差为3.667%,预警分析效果良好,较其他3种机器学习方法泛化拟合能力更强、效率更高。

Abstract: To improve the safety level of construction and get accurate prediction of the safe operation condition of the hoisting operation for fabricated building project, a pre-warning model based on RVM was developed. According to the features of the hoisting operation for fabricated building project, major factors causing frequent accidents were discussed in comparison with the traditional mode, and a early warning index system was established according to 4M1E. The early warning factor was ascertained by attribute reduction algorithm in rough set(RS). A mixed kernel function was introduced and an RVM model was built, whose kernel parameters were determined by IPSO optimization. The model was applied to 5 projects as an example. The data on these projects were input for training and simulation. As the case study shows, the results obtained by using the model are basically consistent with the actual situation.The fitting accuracy, generalization ability and efficiency of the model are better than those of the three other machine learning algorithms.
