建立了地铁工程项目质量、成本、进度、安全指标体系,将工程项目管理中的质量、成本、进度、安全4大控制目标纳入集成动态体系中.利用多元统计方法中的PCA法,将影响4大控制目标的17个因素进行降维处理,得到4个主成分,根据4个主成分的特征向量,对主成分进行归类重组.通过对比重新定义后的4个主成分的得分排名和综合评价得分排名,进行地铁工程目标集成化动态分析,最终运算分析的结果表明,结论符合实际地铁工程项目管理的可能情况.%This paper establish the index system of metro project which included four control targets of the engineering project management that is quality,cost,construction period,safety into integrated dynamic system.We realized the PCA dimension of the 17 indexes in the set and got four principal components by using PCA of multivariate statistical methods.According to the feature vector of four main components,the main ingredients are classified and reorganized.By comparing the scores ranking of four redefined main components and evaluation scores ranking,we conduct integrated dynamic analysis of metro project objectives.Finally,the results of case study shows the conclusion is in line with the possible situations of the metro project management.
