基于灰色系統(tǒng)理論的高速公路價值分析
[Abstract]:In order to quantify and predict the value of expressway, determine the main influencing factors of the value of expressway, and ensure the maintenance and increase of value of expressway, a grey forecasting model is established to predict the value of expressway. And through the residual test to verify the accuracy of the model; grey correlation analysis method to find the main factors of value, determine the linkage between the factors, and Fokienia high speed as an empirical analysis object, Empirical analysis of the model is carried out. The results show that with the residual value of 0.642 0, the value of FokienExpressway in the next 3 years is 4.70218 billion yuan, and the net cash flow and maintenance business cost, operating income, levying business cost, land rent of Fokien-based high speed value are 4.70218 billion yuan in the next three years. The correlation degree of the related factors such as road administration expenditure, monitoring business cost, road production depreciation and so on is 0.98 / 0. 94 / 0.90 / 0.90 / 0.80 / 0.87 / 0.83. Among the influencing factors, the correlation coefficient between operating income and levying business cost is 0.96, which is higher than that of other influencing factors. The correlation coefficient between road production depreciation and monitoring business cost is 0.94, the correlation degree is high, the correlation coefficient between highway expenditure and monitoring business is 0.99, the correlation degree is high, the model can be used to forecast the value of expressway. The grey correlation analysis can be used as an effective method to find out the main cause of value influence and to determine the linkage relationship between the influencing factors. The results can provide the basis for the implementation of value management in expressway.
