基于云模型的装配式建筑施工安全综合评价

Comprehensive Evaluation of Construction Safety of Prefabricated Building Based on Cloud Model

针对装配式建筑在施工作业过程中存在的安全问题,考虑其模糊性和随机性的特点,建立基于云模型的装配式建筑安全综合评价模型。首先,建立人的因素、物的因素、管理因素、环境因素的评价指标体系,采用C-OWA算子法和熵权法确定组合权重;其次,由安全评价等级和评估数据分别确定标准云和综合云的数字特征,通过计算两者的相似度得到评价等级结果;最后,以某项目为例,按照上述方法进行装配式建筑施工安全综合评价。

Considering the fuzziness and randomness of prefabricated building in the construction process, this paper establishes a comprehensive evaluation model of prefabricated building safety based on cloud model. Firstly,establishes the evaluation index system of human factor,material factor,management factor and environment factor,and determines the combined weight by C-OWA operator method and entropy weight method. Secondly,determines the digital features of standard cloud and synthetic cloud from the security evaluation level and the evaluation data,and obtains the evaluation level by calculating the similarity between the two. Finally, taking a project as an example,carries out the comprehensive evaluation of construction safety of prefabricated buildings according to the above method,and the evaluation result is very safe.
