【Abstract】 Based on the grey system, a grey developments model GM(1, N ) is put forward with optimization of the context value and coefficient of model. This model overcomes the deficiency and extends the extension of existing GM (1, N ). It has high precision and it is easy to use. Some examples of line drawing processing with GM(1,2) and GM(1,3) model are given. The results from the examples show that the model is simple and practical, and have a generalizing value in the field of CAD.更多还原
