可调式灰色GM(1,1)模型

灰色模型是灰色系统理论的重要内容，灰色预测、灰色决策、灰色评估等许多理论都是通过建立灰色模型来处理的，由于离散函数的导数不存在，因此，如何处理导数信号，是建立灰色模型的关键。本文根据灰色ＧＭ（１，１）模型的建模机理，指出现行建立模型方法的不确定切之处，给出处理导数信号即背景值的方法，由此导出可调节灰色ＧＭ（１，１）模型。

Adjustable Grey GM(1,1) Model

WT5BZ]Grey model is the important content in grey system theory, many problems such as grey forecasting, grey policymaking and grey estimating are solved by setting up grey model. The derivative of dispersed function doesn't exist, so that, how to deal with the derivative is the key to set up grey model. From the building mechanism of grey model, we have pointed out the undefinitude of the current method to building grey model and given the method to handling derivative, from this, the adjusting grey model has been produced.
