摘要
本文在文献[1]中GM(1,N)模型的建模机理上,讨论了在贫信息情况下GM(1,N)模型的建模方法,并用广义逆的方法导出了问题的范数最小解的显式表达式.用一个实际例子对新的建模方法进行了说明。
Based on the modeling principle of GM(I ,N) modlel which was introduced in pre. [1],a modeling method for GM(I ,N) model with insufficient information was discused. The minimum norm solution of the problem was derived by means of generalized inverse. A practical example was given to illustrate the new modeling method.
