插入值方法的灰色建模

Grey Modeling of Inserting Value

分析了“电视机问题”中GM(1,1)模型不准确的原因 ,提出了插入值的GM (1,1)建模思想 ,运用分段建模思想和新陈代谢建模思想 ,重新解答“电视机问题” ,并给出了建模方法。计算结果表明 ,这 2种方法明显提高了建模精度 ,具有重要的理论与实践意义。

The reason of the uncertainty of the GM(1,1) model in TV problem is analysed and the GM(1,1) modelling method of inserted value is put forward. The television predicate problem is reinterpreted with the subsection modelling idea and metabolism modelling idea and the method of modelling is also put forward. The result of practice showed that these two methods improved the modelling accuracy greatly and had important sense of theory and practice.
