| Abstract: | Through the studies on current grey correlation models, the correlation coefficients are calculated based on relative slope difference between two adjacent samples point of the corresponding curves, the weights of correlation coefficients of each indicator are calculated based on deviation maximization and maximum entropy principle ,therefore, an improved grey correlation model is set up. Example tests show that the results from this method are consistent with the results of quantitative analysis, this method has better analytic effect and has higher reliability and practicability |
