Abstract :
Increasing the smooth degree of data series is key factor in grey modeling. In this paper, a method to enhance smooth degree by means of x -xm (m>0) transformation is put forward. Theoretically it has been proved that the smooth degree of data series can be enhanced greatly by using this transformation, and practical application shows the effectiveness of the approach proposed in this paper
