| Abstract: | 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. |
