A new grey buffer operator and its application

What is it about?

The prediction of shock disturbed systems is always a major challenge in the field of grey prediction. Considering the characteristics of grey buffer operator, this paper proposes a new grey buffer operator based on inverse accumulation, new information priority and logarithmic function to cope with the prediction challenge. In addition, some relevant properties of the new grey buffer operator are discussed in this paper, including adjustment intensity and smoothness. The new grey buffer operator is used to process monotonically increasing sequences, monotonically decreasing sequences and oscillating sequences, respectively. Experimental results show that the proposed buffer operator can effectively improve prediction accuracy.
