Multicriteria Optimization in Wastewater Management
In this chapter we consider the goals and objectives arising in wastewater management in the context of a multiobjective analysis. This allows, among others, the individual consideration of (1) the overflow volume (i.e., the total amount of released water), (2) the pollution load in the released water, and (3) the cost of the generated control. Given a specific sewage network and data of typical inflow scenarios, a multiobjective offline analysis of the problem and, in particular, of the trade-off between the different goals provides the decision maker with valuable information of the problem characteristics. This information can then be used to specify a suitable scalarized, single-objective optimization problem for the real-time optimal control that represents the decision makers preferences in a best possible way. If an efficient solver for such scalarizations is available (which is the case for the problems considered here), this leads to an efficient online procedure that is justified by an extensive offline problem analysis.
Even though the methods presented in this chapter were tailored for wastewater management problems, they are also applicable in the context of the other applications mentioned in this volume.
