基于灰色关联度的电缆排管工程施工质量评价

Evaluation on Construction Quality of Cable Conduit Project Based on Grey Correlation

将灰色关联分析及层次分析法引入电缆排管工程施工质量的评价中,建立了灰色关联分析综合评价模型。从分项工程的角度提炼了31个评价指标,利用灰色关联分析计算各指标的关联系数,并用层次分析法确定各指标的权重系数,然后通过权重系数矩阵与灰色关联系数矩阵相乘得出灰色关联度,以关联度的大小评价质量的优劣。最后通过实际算例表明该方法评价结果符合实际,有益于施工单位改善薄弱环节,提高施工水平。

The grey correlation analysis and the hierarchy analysis method were introduced to evaluate the construction quality of the cable conduit project.The grey correlation analysis comprehensive evaluation model was established.Thirty-one evaluation indexes were refined in the view of subentry projects.The correlation coefficients of the indexes were calculated according to the grey correlation analysis,and the weight coefficients were determined through the hierarchy analysis method.By multiplying the weight coefficients matrix with the grey correlation coefficients matrix,the grey correlation was then obtained.The construction quality can be evaluated based on the correlation value.Finally,the practical calculation example showed that the results conformed to the reality.The contribution in this study was beneficial for the contraction unit to find the weaknesses and to improve the construction level.
