| 摘 要： | 结合运用组合函数法，尤其是对数函数和幂函数在进行原始数据列转换后能提高数据列的光滑度和预测精度的优点，提出了基于组合函数法的灰色预测模型，利用此模型实例预测某油田的年产量，并利用相对误差法将预测值与实际值进行精度检验，取得了较好的结果。

| Abstract: | According to the use of composite function method,especially the logarithmic function and power function,the smoothness and precision degree of column data format are improved by transforming the original data.In this paper,a Grey Model based on composite function method is proposed in combination with that merit and the Model is taken to predict the annual output of a certain oil field.By relative error method,the predicted values are compared with the actual ones for accuracy test.The results show that th... |
