| Research Abstract |
Recently, torrential rains are observed all over Japan and urban areas often suffer from floods. The effective use of current equipments is expected to cope with these floods. The purpose of this study is to propose a method for making plans for operating the pumps of storm water pump stations only from easily accessible data. The water level and outflow data are already measured in many pump stations and the rain prediction data will be obtained from Nowcast data, which are publicly provided by Japan Meteorological Agency. In this study, a linear ARX model was used for predicting the future water level and the parameters of the model were recursively identified. The optimization problem was formulated and the program for calculating the optimal plan of operating water pumps was constructed. The proposed method was evaluated in numerical simulations by using actually measured data.
