基于熵权—集对分析模型的建筑安全管理评价

Evaluation of construction safety management based on entropy weight-set pair analysis

针对建筑安全管理评价中各评价指标的模糊性和不确定性,将熵值和集对分析理论应用于建筑安全管理评价中,依据评价指标和评价标准界限值的关系,对建筑企业安全管理状况进行同一、差异和对立的集对分析,计算各评价指标联系度,并采用熵权赋值法,确定了各评价指标的权重,计算各建筑企业的综合联系度,经实例分析表明,基于熵权集对分析模型的评价结果合理。

In view of the fuzziness and uncertainty of evaluation indicators for construction safety evaluation,the theory of entropy and set pair analysis is adopted. The connection degree of each index value to the classification standard is calculated through the identity,difference and antagonism set pair analysis. Then,the weight of each index is determined by information entropy weight method. After that,the comprehensive connection degree of the safety management performance of construction are calculated. The application result of this model to an example shows that the result based on entropy weight-set pair analysis is reasonable.
