【Abstract】 Through taking pumping station’s annual min im um cost as the objective function and the number of pumps as optimization variab le, and considering variation process of water supply discharge with time, the o ptimization model for selection of pump type was proposed in this paper. In view of the characteristics of pump type selection, the genetic algorithm was adopte d to solve the model of pump type optimal selection. The method can not only imp rove the calculating efficiency, but also get optimum pump combination scheme in a large solution range, and the annual cost of pumping station can be minimized .更多还原
