City water supply system daily plan scheduling decision-making method

The invention discloses a city water supply system daily plan scheduling decision-making method, comprising: first, constructing a scheduling associated data set with a historic daily water requirement sequence, a control point pressure sequence and a daily scheduling scheme as a basic scheduling associated data unit; second, removing the data units of irregular condition days according to an associated preprocessing method; third, employing a water requirement sequence as a characteristic attribute to classify the set into a plurality of subsets, and sequentially removing the statistically unreasonable data units in the subsets through a statistics examination method; and finally, employing a predicted daily water requirement sequence as a characteristic attribute to predict a category, and providing a reasonable predicted daily plan scheduling scheme. The method eliminates simple artificial experiences, makes scheduling decisions more scientific and reasonable, and provides technical ideas suitable for the real-time scheduling decision-making of a water supply system.
