The Novel Triangle MGM(1,m,N)Model and Its Applications
文献摘要：
The MGM(1,m,N)model is an effective grey multi-variate forecasting model that consid-ers multiple system characteristic sequences affected by multiple factors.Nevertheless,it is regularly inaccurate in the application.This is because the model requires a strong correlation between the system characteristic sequences.That reduces the applicability of the model.To solve this problem,this paper proposes a novel multi-variate grey model.This model does not require a certain correlation between system characteristic sequences and has higher applicability.Through numerical integration,a two-point trapezoidal formula,and a recursive method,the time-response expressions of the two model forms are obtained.Some properties of the proposed model are further discussed.Finally,the validity of the proposed model is evaluated by using two real cases related to China's invention patent development.The results show that the novel models outperform other models in both simulation and prediction applications.
