摘要
由于变电工程造价的影响因素众多,造价数据离散程度大,给造价分析与控制工作带来很大困难。本文对变电工程造价影响因素进行了定性识别,分别采用主成分分析、多元线性回归和通径分析法,借助于SPSS软件的数据分析功能,筛选出110kv变电工程造价的关键影响因素,并对其影响程度排序。
As transmission and transformation projects′factors are numerous and the discrete degree of cost data is large,it′s difficult to analyze and control the cost.This paper qualitatively identifies the influence factors of power transformation projects cost.Data models of principal component analysis,multiple linear regression analysis and path analysis are successively used to select and rank the key influence factors of 110 kv power transformation projects cost with the aid of the SPSS data analysis software.
