Research on Intelligent Construction Site Evaluation Indicators Based on Decision Laboratory Analysis and Ordered Weighted Average Operator

为综合评估目前智慧工地建设情况,结合决策实验室分析法和有序加权平均算子构建智慧工地建设评价模型。首先,利用文献法和专家法构建智慧工地评价指标体系,其次,通过DEMATEL计算综合影响矩阵,分析各指标之间的影响关系,找出原因指标与结果指标,最后,计算基于OWA算子的指标权重,进而计算各指标综合权重。结果表明:智慧工地建设影响指标之间有着强烈的关联影响作用,其中安全管理、人员安全管理综合影响作用最大,研究验证了模型的可行性与有效性。

In order to comprehensively evaluate the current situation of smart construction site construction,a smart construction site construction evaluation model is constructed by combining decision laboratory analysis method and ordered weighted average operator.Firstly,a smart construction site evaluation index system is constructed by using literature methods and expert methods.Secondly,a comprehensive impact matrix is calculated by using DEMATEL to analyze the impact relationship between various indicators,identify the cause indicators and outcome indicators.Finally,the weight of indicators based on the OWA operator is calculated,and the comprehensive weight of each indicator is calculated.The results indicate that there is a strong correlation between the impact indicators of smart construction site construction,in which the comprehensive impact of safety management and personnel safety management is the largest.The research has verified the feasibility and effectiveness of the model.
