Based on the optimum segment of historical data,the equivalent dimensions additional grey correct model is proposed,so it is a good solution to this problem.

To improve the accuracy of electricity price forecasting, the paper presents a optimal weighted geometric combined forecasting method, which makes use of the information of second-index flatness, adaptive neuron-fuzzy inference system and grey model of modification comprehensively.

This paper develops grey model,and offers modified grey model,and uses it to embankment settlement research.
