基于熵权法和集对分析法的预制构件安全风险评价

Evaluation of Safety Risks of Prefabricated Components Based on Entropy Weight Method and Set Pair Analysis Method

装配式建筑的施工过程是一个复杂而严谨的过程。为了保障装配式建筑的质量安全,降低装配式建筑安全事故的发生概率,针对影响装配式建筑安全的重要因素,确立人员、物料、机械、技术、资金、环境和管理等7个一级安全风险指标及25个二级指标,以此构建预制构件安全风险指标体系,再结合熵权法客观确定预制构件安全风险指标权重,利用集对分析法建立预制构件安全风险评价模型,对预制构件的安全风险进行分析,为预制构件的安全风险评价提供一种新方法。

The construction process of a prefabricated building is a complex and rigorous process.It can ensure the quality and safety of the prefabricated building,and reduce the probability of accidents in the prefabricated building.According to one of the important factors affecting the safety of prefabricated buildings,seven first-level safety risk indicators and 25 second-level indicators such as personnel,materials,machinery,technology,capital,environment and management are established to analyze the safety risks of prefabricated components.In this way,the safety risk index system of prefabricated components is constructed.Then the entropy weight method is used to objectively determine the weight of prefabricated component safety risk indicators.The set pair analysis method is used to establish the prefabricated component safety risk assessment model,which provides a new method for the safety risk assessment of prefabricated components.
