摘要
把模糊理论引入大坝观测领域,提出建立预报模型的一种新方法。新模型的优点是预报不受子样资料区间的限制,并且当因变量与自变量呈非线性关系时仍然适用。虽然模糊模型需要的"训练"数据较多,且计算结果显示其精度较通常的线性回归方法略有降低,但弥补了线性回归方法的缺陷,具有一定的实用意义。
Being involved in the dam ovservation field,the fuzzy theory helps establishing a new method of forecasting model.The fuzzy forecasting model is not limited by the subsystem. In addition,the new model can also be fit when the independent valiables are nonlinear with the valiable and self-variable.Though the fuzzy model needs more training data,and the accuracy of the new method is a bit worse than the traditional linear regression method, but it can remedy the defect of traaditional method and it is valuable in practice.
