摘要
提出多变量灰色模型（ｍｕｌｔｉ－ｖａｒｉａｂｌｅｇｒｅｙｍｏｄｅｌ）—ＭＧＭ（１，ｎ）模型，它是单变量的ＧＭ（１，１）模型在多变量（ｎ元变量）情况下的自然推广。通过对国有建筑施工企业就业人数和城镇集体建筑施工企业就业人数的建模和预测，表明ＭＧＭ（１，ｎ）模型的精度高于分别单独使用的ＧＭ（１。
In this paper, a multi-variable grey model (MGM(1,n)) is presented, which generalizes the univariable GM(1,1) model to the multi-variable system.A practice example is given about the total employees of national operated and urban collective architectural enterprises, in which a comparison about the modeling and prediction results is made between two cases:using the MGM(1,n) model only and using the GM(1,1) seperately. It is shown the MGM(1,n) model has a higher accuracy.
