摘 要:随着近年来电网投资的不断增长,控制工程造价投资价格的必要性日益突出。不断涌现的新技术以及新方案的应用,导致传统的输电线路工程造价指标已不能准确的反映工程造价水平。针对这一问题,运用灰色关联理论的GM(1,1)模型,收集不同年份的输电线路工程数据,以影响工程造价的主要材料价格占整体工程投资的比例作为研究对象进行预测,根据预测结果对未来材料价格进行合理调整管控,以达到工程结余率降低的目的。With the continuous increase of power grid investment in recent years,the necessity of controlling project cost investment is becoming more and more prominent.With the application of new technologies and new schemes,the traditional cost index of transmission line project can not accurately reflect the level of project cost.In order to solve this problem,we apply the GM(1,1)model of grey correlation theory,and collect different years of transmission line proj‐ect data.We make a prediction that the main material price to influence the project cost accounts for the proportion of the whole project investment as the research object.We make the rational adjustment,according to the results of predic‐tion for the future material price controls,in order to achieve the purpose of project balance ratio decreased.
