Aplikacja in Smart Water Networks: From Theory to Practice

Smart water networks rely on a dense layer of instrumentation: pressure transducers, flow meters, water quality sensors, and smart meters at consumer points. This data beed into hydraulic models that simulate water flow, pressure distribution, and conditiant transport. The optimization problem then integrates models with coss functions and performance metrics.

Pareto- Based Methods vs. Scalarization

Pareto-based methods (like NSGA- II) directly find a set of non-dominated solutions. In contrast, scalarization methods convert the multi- objective problem into a single objectiva by combination the objectives with with waxts (np., waxted sum) or by limiting all but on e objectiva (epsilon- objective methods).
