Abstract
The major objectives were to: Build a computerized testbed for simulating the operation of a water distribution system over a variable time and, Develop control methods for on-line operation which minimize operating costs and pump cycling while maintaining satisfactory customer service. The objectives required the development of: Daily system demand model from real operating data; Standard network model; Regression model, from operating data; Control models for turning pumps on/off; Energy/cost model to evaluate a control model; and Dynamic capability for operating the regression or network models over a variable time.
