The Optimization Solution of GM(1,1) Model and Its Arithmetic

摘要

This paper put forward several kinds of new optimization solution method of GM (1, .1) model. In order to deal with the limitation of optimization model based on the least squared method (LSM). Based on minimizing the average relative error, this paper has put forward the accurate optimization arithmetic of GM (1, 1) model and provided the mathematic proofs. It solved the consistency problem of optimization goal function and tested the method of model accuracy. An example indicates the optimized model put forward in this paper has much higher simulation accuracy.
