灰色系统SCGM(1,h)_c模型的拓广

On the Extensions of the Grey Forecasting Model SCGM(1, h ) c

对于一类贫信息耦合多因子系统，建立了灰色系统ＳＣＧＭ（１，ｈ）ｃ模型的三种拓广模型，即ＳＣＧＭ（２，ｈ）ｃ模型、ＳＳＣＧＭ（１，ｈ）ｃ模型、带有时滞的ＳＣＧＭ（１，ｈ）ｃ模型。

Forecasting models are very important in the grey system theory. For an information poor system with correlated multifactors, SCGM (1, h ) c forecasting model is presented that imply dynamic characteristics. The forecasting model has been applied to some forecasting and planning. SCGM (1, h ) c-the grey forecasting model is extended to three cases, i.e., SCGM (2, h ) c model, model with time SSCGM (1, h ) c model, and SCGM (1, h ) c model with time relay, and the formula of parameter identification and solutions for these models are given.
