    • A predicting system configured to predict an inflow volume of rainwater includes a rainfall volume measuring unit for measuring a rainfall volume that has fallen by a present time, a rainfall volume predicting unit for predicting a rainfall volume in a future, and an inflow-volume measuring unit for measuring an inflow volume of rainwater that has flown into an objective facility by the present time. The system also includes a model identification unit, which has a non-linear model having a Neural-Network model for calculating an inflow volume of rainwater from a rainfall volume, and which has a parameter determining part for determining a degree and coefficient parameters of the non-linear model, based on the rainfall volume that has fallen by the present time measured by the rainfall volume measuring unit and the inflow volume of rainwater that has flown into the objective facility by the present time measured by the inflow-volume measuring unit. An inflow-volume predicting unit is adapted to predict an inflow volume of rainwater flowing into the objective facility in the future, based on the rainfall volume in the future predicted by the rainfall volume predicting unit, according to the non-linear model determined by the model identification unit. Thus, the inflow volume of rainwater flowing into the objective facility can be predicted more accurately even if there is a non-linear relationship between the rainfall volume and the inflow volume of rainwater.
    • 配置为预测雨水流入量的预测系统包括:用于测量目前下降的降雨量的降雨量测量单元,用于预测未来降雨量的降雨量预测单元和流入量测量 用于测量当前流入目标设施的雨水的流入量的单元。 该系统还包括模型识别单元,其具有非线性模型,具有用于从降雨量计算雨水的流入量的神经网络模型,并且具有用于确定雨水的程度和系数参数的参数确定部 基于由流量测量单元测量的当前由降雨量测量单元测量的当前时间的降雨量和已经流入目标设施的雨水流入量的当前时间的非线性模型。 流入量预测单元根据由降雨量预测单元预测的将来的降雨量,根据由下式确定的非线性模型,预测未来流入目标设备的雨水的流入量 型号识别单元。 因此,即使降雨量与雨水流入量之间存在非线性关系,也可以更准确地预测流入目标设施的雨水的流入量。
