In grey forecasting model, there are two unsolved problem, the theoretical basis of transformation from discrete form to continuous form and the forecasting stability, which puzzled those who are absorbed in grey theory. Many scholars used all kinds of methods to revise the model, and they have made some progress, but they didn't solve it absolutely in principle. To solve these two problem and on the basis of the angle from discrete to discrete, discrete grey forecasting model(which is called DGM(1,1)) is c...
