Abstract:
The forecasting model of exponential smoothing is a valid method in forecasting and decision-making.Based on the practical datas and according to the characteristic(linearity trend) of the fact coal wastage in Chongqing(recently),the forecasting model of twice exponential smoothing model is set up and the model is applied to forecast the caol wastage in Chongqing.The forecast results show that the errors between the forecast values and the fact values error little and the model may be well applied on the forecast of the coal wastage in Chongqing.It also shows that the decision-making can based on the result well.
