A New Method for Solving Discrete Nonhomogeneous Power Model
摘要
The discrete model of the inhomogeneous GM(1,1) power model is obtained by changing the inhomogeneous GM(1,1) power model. According to the discrete model, the time response formula with any term as the initial value is derived, and the general term formula is obtained by deformation treatment. Then, under the objective function with the minimum average relative error, the parameters in the general term formula are optimized at the same time to obtain the optimal parameter value, and summarize the modeling steps. At last, different models are established through examples, and the simulation accuracy is compared to verify the operability and superiority of the model in this paper.
