摘要
Based on the basic model of grey systematic. prediction., this paper presents a kind of direct solution, which does not need to consider the selected order of variables, thus overcoming the limitations of the original nested solution. The original forecasting model., through the equivalent transformation, is changed into linear equations, and then transforming its augmented matrix into an upper triangular matrix by the row elementary transformation, so we could obtain the predicted values. It can be seen from the simulation and forecasting results of a group of approximate standard exponential series in this paper, that the new solution has a very high simulation and prediction precision; moreover, it is easily calculated by MATLAB. An instance also shows that the new solution has a higher simulation precision and more reasonable forecasting values than the original nested solution.
