基于组合赋权和理想解法-灰色关联的公路工程施工安全评价

为了改善公路工程施工安全评价水平,有效减少施工安全事故的发生,建立了基于理想解(technique for order prefer-enceby similarity to ideal solution,TOPSIS)法-灰色关联的公路工程施工安全评价模型.通过组合赋权方法求得组合权系数,赋予评价指标权重,以充分利用评价指标信息;结合TOPSIS法和灰色关联分析可以分别对评价对象位置关系和态势变化进行分析的优势,引入偏好系数对欧式距离和灰色关联度进行综合,求得相对贴近度,从而实现对各个评价对象的综合评价.实例应用分析表明,求得的最终评价结果合理可靠,说明该模型具有一定的科学性和实用性.

Construction safety evaluation of highway engineering based on combination weighting and TOPSIS-Grey correlation

In order to improve the level of highway construction safety evaluation and effectively reduce the frequency of construction safety accidents, a highway construction safety evaluation model based on TOPSIS-Gray correlation was established. The combination weight coefficient is obtained by the combination weight method, and the weight of evaluation index is given to make full use of the evaluation index information. Combined with TOPSIS method and gray correlation analysis, the advantages of analyzing the position relationship and situation change of the evaluation objects can be analyzed respectively. The preference coefficient is introduced to comprehensively combine the Euclidean-type distance and gray correlation degree, so as to obtain the relative closeness degree, so as to realize the comprehensive evaluation of each evaluation object. The results show that the final evaluation result is reasonable and reliable, which indicates that the model is scientific and practical.
