摘　　要：本文探讨并解决了微分动态模型GM(1,1)的严格微分拟合问题,给出了GM(1,1)的严格微分拟合建模法。本文所给建模方法,彻底根除了现有灰色微分拟合法存在的固有误差,拓广了GM(1,1)的应用范围,且计算方法简单,计算工作量小于灰色微分拟合法。文后应用实例表明,本文提出的建模方法具有明显的优点。This paper tries to discuss and solve the problem of the striets fitting of the differential dynamic model GM(1,1), and give a strict fitting method for building GM(1, 1)model. This modelling method completely removes the intrinstic errors of existing grey differential fitting methods, and expands the application range of GM(1,1) Moreover, its computational method is simple, and its computational effort is less than that of the grey differential fitting method. The application examples given in the end of this paper show that the modelling method has obvious advantages.
