灰色模型GM(1,1)直接优化建模
Grey model GM(1,1) direct optimization modeling
摘要
Abstract
The gray model GM(1,1) is a commonly used model in prediction,but it has rather big errors some-times,because its basic form (used to estimate parameters) is not consistent with that of whitenization equation (used for prediction). In order to improve prediction accuracy of models,this paper started with whitenization equation and optimized its solution (time response function ) directly according to some criteria ,such as the mini-mum criterion of average absolute relative errors. This paper selected three-harmony and three-point methods to optimize the initial value of functions. The examples indicate that the directly optimized gray model GM (1,1) has very high accuracy in modeling.关键词
