Forecasting the yield of natural gas in China.

The exponential smoothing methods with the grey model and the generalized Wengshi model have been introduced in the present article. Two new methods for forecasting the yield of natural gas in China have also pointed out based on the exponential smoothing method with the grey model and the generalized Wengshi model. The experimental results show that both models can predict the yield of natural gas in China and the experimental data are in agreement with the quantitatively analytical conclusions drawn from the calculated data. This proves that two types of new models can be used to forecast the yield of natural gas. It results in good economic and social benefits in China. [ABSTRACT FROM PUBLISHER]
