1. A distributed water flow predicting device for predicting an hourly distributed water flow rate for a day to be distributed from a purification plant or a service reservior of a water-supply facility, the device comprising:

  • actual seasonal weather data processing means for processing actual seasonal weather data, based on stored past actual weather data, and information of a weekday or a holiday;

    seasonal distributed water flow data processing means for processing actual seasonal distributed water flows, based on actual hourly distributed water flows for every day;

    seasonal prediction model learning means for learning weight coefficients of a neural network model by back propagation over a prediction model for predicting daily distributed water flows and specific characters of an hourly distributed water flow pattern for a season, based on processed data supplied by the seasonal actual weather data processing means and the seasonal distributed water flow data processing means, so as to identify the prediction model; and

    seasonal distributed water flow predicting means for predicting daily distributed water flows and specific characters of an hourly distributed water flow pattern for a required season by using the prediction model, based on inputted information about the weather, temperature, a weekday or a holiday, for comparing the specific characters of an hourly distributed water flow pattern given by the prediction model with specific characters of past actual distributed water flow patterns stored in the seasonal distributed water flow data processing means so as to retrieve a most similar hourly distributed flow pattern from the past actual distributed water flow patterns, giving the retrieved pattern as a predicted hourly distributed water flow pattern, and for multiplying the predicted daily distributed water flow by the predicted hourly distributed water flow pattern to predict an hourly distributed water flow.
