| Abstract: | The optimization of the grey model GM(1,1) is made by combining the conventional grey model GM(1,1) with the fuzzy regression model,and the advantage of limited modeling data and the forecasting capability of the grey model GM(1,1) are kept.The solving method for the optimized grey model GM(1,1) based on the fuzzy regression theory is obtained by defining the left distance formula,the middle distance formula and the right distance formula of triangular fuzzy numbers. |
