【摘要】：为准确评价装配式建筑项目安全绩效等级,考虑到评价的模糊性和随机性,在专家打分的基础上,提出一种装配式建筑项目安全绩效云模型评价方法。首先,根据装配式建筑作业空间并行多维的特点,按人-机-料-法-环(4M1E)5要素确定评价指标体系,采用层次分析法(AHP)和熵权法计算指标组合权重;其次,确定安全绩效考核等级标准云与项目综合评价云,通过计算两者的云相似度确定项目安全绩效等级;最后,以某市试点项目为例,按照该方法确定项目安全绩效等级。结果表明:该试点项目安全绩效等级为优,符合实际情况;与其他常规综合评价方法相比,结果更加客观、准确。
[Abstract]:In order to accurately evaluate the safety performance grade of prefabricated construction projects and considering the fuzziness and randomness of evaluation, a cloud model evaluation method for the safety performance of prefabricated construction projects is proposed on the basis of experts' scoring. Firstly, according to the characteristics of parallelism and multi-dimension of prefabricated construction operation space, the evaluation index system is determined according to the factors of man-machine-material-method-ring 4M1EN5, and the combined weight of indexes is calculated by AHP (Analytic hierarchy process) and entropy weight method. Determine the safety performance evaluation standard cloud and project comprehensive evaluation cloud, by calculating the cloud similarity between the two to determine the project security performance grade; finally, take a city pilot project as an example, according to this method to determine the project security performance grade. The results show that the safety performance grade of the pilot project is superior and accords with the actual situation, and compared with other conventional comprehensive evaluation methods, the results are more objective and accurate.
