Description
Summary:In the process of transportation construction, the developping trend of government financial investment to transportation engineering is a key that enterprises need to grasp accurately. On the basis of the existing study results of GM(1,1) model, this paper presents a novel procedure unifying improved initial condition value and optimized background value of GM(1,1) model, constructs a novel GM(1,1), and compares original GM(1,1) model with this novel GM(1,1) model in modeling precision through an example about the prediction of government transportation engineering investment. The findings indicate the superiority of this novel GM(1,1) model in forecasting modeling.
