本文在深入研究递减曲线类型特点的基础上,应用现代控制论的方法,提出了一种递减曲线的多功能预测模型。该模型对任何一种递减类型具有普遍的适应性,因此无须再去判别递减类型。通过计算实例证明了该模型预报结果的可靠性和模型的多功能性。此外,该方法也比较简单,易于掌握。 On the basis of deeply studying the characteristics of the decreasing curve type, this paper proposes a multifunctional prediction model of decreasing curve by applying the modern control theory. The model has universal adaptability to any of the decreasing types, so there is no need to discriminate the decreasing type. The reliability of the model forecasting results and the versatility of the model are proved by calculation examples. In addition, the method is relatively simple and easy to grasp.
