Research of Enhancing Smooth Degree of Sequence Based on Multiplex Transformation and Its Application
In this paper, the method of improving GM (1,1) model is put forward based on multiplex transformation. First, the necessary and sufficient condition of smooth sequence is given. It is proved that smooth degree of sequence can be enhanced under some conditions. Secondly, the new concept of multiplex transformation is proposed because the enhancing smooth degree of sequence is limited by adopting unitary transformation. Thirdly, the mechanism of enhancing smooth degree of sequence based on multiplex transformation is studied and the steps of improving GM (1,1) model based on multiplex transformation is presented.Finally, the method is applied in building the model of per-capita power quantity and the results show the method presented in this paper is effective.
