Dynamic Programming Example Analysis of a Pump Station

For a pump station supplying water, this paper is analyzing the real situation of the station considering all the real existing factors related to set a mathematic model, in the goal of reducing the cost thru adjusting the water flow in different time sections. The dynamic programming model method with detailed analyses is induced illustrated by an example of optimizing the cost of a single unit in a single day with a fixed water-supply amount in the paper. More interesting, a special case of this model is illustrated to proof that non-stop pump working is more power saving than intermittent working given the unchangeable electricity price.
