- In the last two decades, water consumption in Germany has been decreasing, which
causes the water tanks and pipes in water distribution systems to work inefficiently.
This paper proposes a method that supports the planning process for tanks in water
distribution systems. The method uses a combination of network reduction, mathematical
optimization and hydraulic simulation. The mathematical optimization model is
a non-convex Mixed Integer Quadratically Constrained Program (MIQCP) that is solved
by a piecewise linearization. As this may lead to many binary variables and therefore
high computing times, the size of the water distribution system model is reduced
before building the optimization model. After applying several network reduction
techniques and using a piecewise approximation of the original model, there may
be some hydraulic differences between the original network model and the reduced
network model. To make sure that the solution obtained in the optimization process
is feasible in the original water distribution system model, the solution is verified
by a hydraulic simulation. If the solution is not feasible, the reduced model
has to be modified and solved again until the hydraulic simulation verifies a
solution as feasible. In this paper, each of these processes is described and
the results indicate the usefulness of each of them.@eng
