| Abstract: | An improved GM (1, 1) called metabolic GM (1, 1) model is proposed in order to improve prediction accuracy. In traditional GM (1, 1), initial conditions and identifying parameters no longer change once they are confirmed. However, it is not fit for dynamic and long data prediction. This model which can choose the best initialization conditions and dynamically confirm identifying parameters like a metabolism process is introduced. This metabolic GM (1, 1) model is applied to predict time-displacement data for a Health Intelligent Monitoring System for Large-Scale Roof Lattice Structure of Shenzhen Civil Center and achieves good results. |
