Sulfur dioxide is an important source of atmospheric pollution. It is harmful to ecosystems, buildings and humans. Many countries are developing policies to reduce sulfur dioxide emissions. In this paper, prediction of China's sulfur dioxide emissions is studied by discrete grey model with fractional operators. The forecast result shows that the amount of sulfur dioxide emissions is steadily decreasing...
To reveal the change law of the simulation error of grey model GM(1,1) with translation transformation applying on the original sequence, in this paper, the experiments based on 55 real world data sequences have been conducted to study how the translation transformation influences the grey models' error characteristics. The results show that a larger translation transformation can make the total error...
It is very important to forecast the number of urban migrant workers in a city, but various traditional prediction models cannot tackle such situation effectively. To solve this problem, this paper builds a novel grey prediction model based on kernel and information field of interval grey number. Then this proposed model is applied to establish the prediction model of the number of urban migrant worker...
According to Guangxi agriculture Industrialization, modern agricultural Industrialization competitiveness model is established based on the Grey systems theory, which evaluates and predicts the modern agricultural industrialization competitiveness in Guangxi Beibu Bay Economic Zone. Moreover, modern agricultural Industrialization development process in Yulin City is effectively analyzed referring...
