数据处理的序列弱化逐步优化直接模型

Serial Weakening Step by Step Optimization GM(1,1) Modeling & Method to Data Processing

分析数据处理的现状后 ,运用灰色系统理论 ,建立了数据处理的序列弱化逐步优化直接GM(1,1)模型 ,给出了精度检验方法 ;编制Matlab程序 ,给出了线图处理实例 ,并与各种灰色模型进行比较 .该模型不需要累加生成和累减生成 ,不仅适合于等间距建模 ,也适合于非等间距建模 ,具有精度高。

Based on Grey system,an serial weakening step by step optimization direct modeling GM(1,1) and method to data processing in engineering field is put forward,the method of precision inspection is introduced.Then,the programming is authorized with Matlab 6.1 language.Two examples are given,their results are compared with the results of other Grey models,respectively.With this model,the data don′t need to be preprocessed and the generations of accumulation plus and subtract don′t need to be made.The method can be used for model establishing at equal interval,as well as at non-interval.It has high precision and is easy to use.The model is simple and practical,and has a generalizing value in the field of CAD.
