摘要

Based on the principle of multi-variable non-equidistant systematic grey prediction, a discrete grey model of systematic prediction is constructed in this paper. This model mainly transforms the original model's identical deformation into linear equations and then get the solution. It can simulate and predicte the data directly. The simulation and prediction accuracy is proved to be higher in the non-equidistant multi-variabl model than the original one according to an application. The proposed model is suitable for not only the equidistant model but also the non-equidistant model, thus, non-equidistant model has broad applying value.
