Modeling Method of Grey System GM (1.1) Model Based Information Reused and It's Application

Objective: To Find a new method that set up grey system GM(1.1) model. Methods: On the Professor DENG Ju-long′s modeling GM(1.1) model method,we set up a modeling method of grey system GM(1.1) model based information reused. Result: The GM(1.1) model that the modeling method of grey system GM(1.1) model based information reused set up not only has better precision than the GM(1.1) model that the traditional method set up,but also has better precision than the GM(1.1) models that other methods set up. Conclusion: The GM(1.1) model that the modeling method of grey system GM(1.1) model based information reused set up not only has simple modeling procedure,but also has better precision than the GM(1.1) models that other methods set up,so the new method has wide-ranging use value.
