改进的离散灰色模型及其应用

Improved Discrete Grey Model and Its Application

在文献研究的基础上,对离散灰色模型作了进一步改进,给出一种预测的新方法.该方法将离散灰色模型中的已知条件作了适当的拓广,从而使新模型具有更高的精度.通过变压器油中溶解气体预测的实例分析验证了该方法的有效性.

On the basis of the research results published in existing relevant references, the discrete grey model is further improved and a new method is given. In this method the known condition of the discrete grey model is expanded properly, which provides the new model with higher precision. The actual case of dissolved gas prediction in power transformer oil is employed to demonstrate the validity of the proposed approach.
