灰色动态模型建模判据及模型改进

Criterion for Construction Model and Improvement Model of Grey Dynamical Model

本文讨论了单序列一阶线性灰色动态模型预测方法在时间序列分析预测中的使网范围问题,提出对哪一类时序问题可直接使用该预测法的判定定理,以及如何根据判定定理对该灰色动态模型预测方法进行改进,扩大其预测范围的具体的新建模方法.

The problem of using range for the simple sequences,first-orderliner grey dynamical model prediction in the time series analysis projec-tion was discussed in this paper.We gave the decision theorem of using the director way about pred-iction for the same parts of the time series problem.And according tothe theorem how it hasimproved the grey dynamical model prediction way.The way of the newconstruction model was explained in the range ofprediction.
