Gray prediction is an important branch of the gray system theory. Six aspects were summarized for the existing research of gray prediction. These are the property research of GM(1,1) model, improvement and optimization of GM(1,1) model, parameter estimation method, optimiza- tion of initial condition, extension and application researches of GM (1,1) model, and research on power model. Finally, two suggestions are made for the future study of gray prediction models.
