摘  要:
The grey model GM(1,1) with a differential format was converted into a difference one to extend GM and then the extended GM model was optimized. The optimal parameter ω * was determined by the fuzzy grey system method to predict the accuracy of GM model. To have a solid theoretical fundamental and a practical value, the method was not only theoretically derived and analyzed, but also verified by a practical application.
