| Abstract: | The grey model (GM) can be used to predict the future data. But sometimes, the precision of forecasted value is not satisfactorys In order to improve the precision of the grey model and make the forecasting result more accurate and rational, this paper presents a new method which is called the minimum method (mini-method). It's principle is first introduced, and it is demonstrated by an example. Finally, the effectiveness of the new method is verified with the grey relational degree (GRD). |
