Development of Markov Chain Grey Regression Model to Forecast the Annual Natural Gas Consumption
Accurate forecasting of annual gas consumption of the country plays an important role in energy supply strategies and policy making in this area. Markov chain grey regression model is considered to be a superior model for analyzing and forecasting annual gas consumption. This model Markov is a combination of the Markov chain and grey regression models. According to this model, the residual er...
متن کاملThe Application of the Grey Disaster Model to Forecast Epidemic Peaks of Typhoid and Paratyphoid Fever in China
OBJECTIVE The objectives of this study were to forecast epidemic peaks of typhoid and paratyphoid fever in China using the grey disaster model, to evaluate its feasibility of predicting the epidemic tendency of notifiable diseases. METHODS According to epidemiological features, the GM(1,1) model and DGM model were used to build the grey disaster model based on the incidence data of typhoid an...
متن کاملApplication of a Hybrid Method Combining Grey Model and Back Propagation Artificial Neural Networks to Forecast Hepatitis B in China
Accurate incidence forecasting of infectious disease provides potentially valuable insights in its own right. It is critical for early prevention and may contribute to health services management and syndrome surveillance. This study investigates the use of a hybrid algorithm combining grey model (GM) and back propagation artificial neural networks (BP-ANN) to forecast hepatitis B in China based...
متن کاملApplication of Grey System Theory to Forecast the Growth of Larch
In this paper, based on grey system theory, the general GM(1,1) forecasting model for the growth of Japanese Larch in Liaoning Province was set up and it has been proof-tested in model precision.Verified by use of the dates of the Japanese Larch with age of 21 and 22, it has been proved that the model was effective in practice. The relative error of GM(11) model for mean DBH was 2.4%and 3.69%, ...
