基于改进TOPSIS的装配式建筑施工安全评价研究

Construction Safety Evaluation of Prefabricated Construction on the Basis of the Improved TOPSIS

为了有效地对装配式建筑项目施工安全进行评价,分析了影响装配式建筑施工安全的主要因素,构建了一套装配式建筑施工安全评价指标体系。基于G1法和熵权的组合赋权改进了优劣解距离法(Technique for Order Preference by Similarity to an Ideal Solution,TOPSIS),构建了装配式建筑项目安全评价体系模型。并通过实例分析,证实了该模型在装配式建筑项目施工安全评价中具有较好的实用性和可行性,从而为企业实施装配式建筑施工安全评价研究提供了一定的参考依据。

In order to effectively evaluate the construction safety of prefabricated construction projects,the main factors influencing prefabricated constructions are analyzed,and a set of safety assessment index system is constructed.Based on the combination between G1 method and entropy weight,TOPSIS(Technique for Order Preference by Similarity to an Ideal Solution,TOPSIS)is improved and the safety evaluation system model of the prefabricated construction project is constructed.Combined with the specific case,it is proved that the model has good practicability and feasibility in the construction safety assessment of the prefabricated construction project,which provides references for the enterprise to implement the safety evaluation of the prefabricated construction.
