【Abstract】 On the basis of the characters of coal mine Input-Output Model,A regres-sive-Autoregressive neural networks for modifing and forecasting direct consuming coefficients (DCCs) is proposed. Combined with the practical study works,some examples for modifing and forecasting DCCs is gived. It’ s a new method to modify and forecast DCCs.更多还原
