摘    要:为了拓广离散GM(1,1)模型的应用范围,建立了近似非齐次指数序列的离散GM(1,1)模型,NDGM(1,1)模型和直接离散GM(1,1)模型,即DDGM(1,1)模型,证明了其可以完全拟合非齐次指数序列,最后将两类离散GM(1,1)对软件进行缺陷预测建模,结果显示,DDGM(1,1)模型具有较高预测精度,可以对后续软件开发中缺陷的存在情况做出相应预测.

关 键 词:GM(1,1)模型  NDGM(1,1)模型  DDGM(1,1)模型  软件缺陷

Abstract:To expand the applied range of discrete GM ( 1, 1 ) model, the non-homogenous discrete GM ( 1, 1 ) model ( NDGM ( 1, 1 ) model) and the direct discrete GM ( 1, 1 ) model ( DDGM ( 1, 1 ) model) were put forward, and it was proved that the models completely fit a non-homogenous exponential sequence. The defect fore- casting modeling results on two types of discrete GM ( 1, 1 ) demonstrated that the forecast precision of DDGM ( 1, 1 ) model is great and the model can forecast the defect of follow-up software development.
Keywords:GM( 1  1 )model  NDGM( 1  1 ) model  DDGM( 1  1 ) model  software defect
