分数阶累加多变量灰色模型FMGM(1,n)及应用
Multivariable grey model FMGM(1,n) with fractional order accumulation and its application
摘要
Abstract
After analyzing the fractional order AGO and IAGO of single variable, formula of multivariable fractional order AGO was deduced; the multivariable grey model FMGM(1,n) with fractional order accumulation was established; the model parameter estimation based on least square method was derived. By taking fractional order and minimum average relative error as design variable and object function, the optimal model was established and the solution program based in Matlab was written. As natural promotion of single variable model FGM(1,1), multivariable grey model FMGM(1,n) with fractional order accumulation reflected the interaction of variables. At last, the numerical example was given to indicate correctness and effectiveness of the model.关键词
