Based on the convolution transformation having the characteristic of enhancing the smooth of the transformation sequence and the Accumulated Generating Operation(AGO) theory,the grey model GM(1,1,t) with linear time term was developed by the convolution transformation with linear sequences to modeling sequences in this paper,which improved the AGO and the grey model GM(1,1) in grey modeling.
根据卷积变换可提高变换序列光滑度的特性和累加生成的机理,对灰色建模中的序列生成方式和GM(1,1)模型加以改进,用线性序列对建模序列作卷积变换,建立带线性时间项的灰色模型GM(1,1,t),实例计算结果表明GM(1,1,t)模型的模拟精度较GM(1,1)模型有较大提高且适用范围更广。
