摘要
针对目前电网生产项目重技术、轻经济的现状,建立针对生产项目的投入与产出定量关联性测算模型,以实现精准投资.首先,提出一套流程框架分析了生产项目指标之间的关联性.其次,对生产项目进行了分类与规模化处理,筛选了适用于该项目的评价指标体系.再次,基于灰色关联法构建了电网生产项目评价指标的关联度测算模型.最后,对某区域的生产项目开展实证分析,以验证所提模型方法的准确性与有效性.
Abstract
In response to the current situation where power grid production projects prioritize technology over economy,a quantitative correlation calculation model between input and output for production projects is established to achieve precise investment.Firstly,propose a process framework to analyze the correlation between production project indicators.Secondly,the production projects were classified and scaled,and the evaluation index system for the project was screened.Once again,a correlation degree calculation model for the evaluation indicators of power grid production projects was constructed based on the grey correlation method.Finally,conduct empirical analysis on production projects in a certain region to verify the accuracy and effectiveness of the proposed model method.
