基于加权主成分分析的公路工程质量综合评价研究

Study on Quality Comprehensive Evaluation of Highway Engineering based on Weighted Principal Component Analysis

提出采用加权主成分分析的公路工程质量综合评价的思想。采用系统分析方法,通过目标分解建立包括各分部分项工程在内的公路工程质量评价综合体系,采用灰色关联度法确定评价指标权重,建立基于加权主成分分析方法的综合评价模型。工程实例表明,该方法有效地利用样本数据对不同方案进行客观评价,显示出其可行性。

The thought was proposed to evaluate comprehensively highway engineering quality using weighted principal component analysis（WPCA）.The comprehensive evaluation systems of highway engineering quality were established including all processes by using systems analysis methods and goal resolvability methods.The weights of evaluation indexes were determined by using grey correlation grade method.And the comprehensive evaluation model of highway engineering quality was established by using WPCA.The concrete engineering example demonstrates that the method can utilize effectively the data of samples to evaluate objectively the different projects which demonstrate the feasibility of the proposed method.
