摘要
本文从ＧＭ（１，１）建模特点出发，提出了一种置零建模的新方法（简记为ＧＭ０（１，１）法）．该方法用于灰色预测时，可使ｎ维非负序列预测所需的观测数据个数从ｎ个减少为ｎ－１个，从而使采样和ＧＭ（１，１）化［１］过程得到优化。
Based on the characteristic Of GM(1,l) modelling, the paperPresents a new method Of zero setting modelling (labeled GM(1,1) method).Whell applied to grey fore￣ing, it can decrease obserVatioll data needed forestablishing a forecasting model of n-dimenSion non-negative seqience fromn to n-1, thus enaviing the Process of Sampling and GM(1,1) tranSformationto be optimized. This method is of practical value.
