Abstract

Improving the smooth degree of modeling data series is key factor of grey model’s precision. According to function transformation theory and grey system modeling theory, elementary study on GM(1,1) model based on function ransformation is given, and the methods of linear function transformation and compound function transformation against modeling data series are put forward to improve model’s precision in the paper. It has been proved that the smooth degree of modeling data series after the two new transformations can be improved. The result of practical application demonstrates use of the two new methods.
