采用基于灰色系统理论的GM(m,n)模型所进行的预测,称为灰色预测。灰色预测可分为数列预测、灾害预测、季节性灾变预测、拓朴预测、系统综合预测。其中,对表示系统行为的序列进行外推预测。称为数列预测。如农业生产中,粮食、生猪、水产品等产量的预测;工业生产中,汽车产量、煤炭产量等的预测;财政金融预测中,货币流通量的预测;医疗卫生预测中,发病率、 Prediction using GM (m, n) model based on gray system theory is called gray prediction. Gray prediction can be divided into sequence prediction, disaster prediction, seasonal catastrophe prediction, topological prediction and system comprehensive prediction. Among them, the sequence of systems that represent the behavior of extrapolation prediction. Known as the sequence prediction. Such as the prediction of the output of grain, pigs and aquatic products in agricultural production; the forecast of industrial output, automobile output and coal output; the prediction of the currency circulation in the financial and financial forecast; the forecast of morbidity,
