| Abstract: | In this paper, a graphic method for grey system model GM(1, 1) is presented. All parameters in the basic solution form of GM(1, 1) can be determined with this method. The result shows that the graphic method is simple and reliable for solving GM(1, 1) model. The comparison between the graphic method and analytic method shows that the former is close to the latter in accuracy. |
