CAD线图数据处理的GM(1,N)模型与方法

Method and Grey GM(1,N) Model of Line-drawing Data Processing in Computer Aided Design

运用灰色系统理论 ,通过优化模型系数与背景取值建立了灰色多因素灰色动态 GM(1,N )模型。该模型克服了现有 GM(1,N )模型的不足 ,扩宽了 GM(1,N )模型的应用范围。运用该模型的 GM(1,2 )、GM(1,3)线图处理实例表明该方法简单实用 。

Based on the grey system, a grey developments model GM(1, N ) is put forward with optimization of the context value and coefficient of model. This model overcomes the deficiency and extends the extension of existing GM (1, N ). It has high precision and it is easy to use. Some examples of line drawing processing with GM(1,2) and GM(1,3) model are given. The results from the examples show that the model is simple and practical, and have a generalizing value in the field of CAD.
