Strengthening mathematical models for pump scheduling in water distribution
Résumé
Pump scheduling is a reputed demand-response tool for drinking water distribution. It is also a notorious difficult optimization problem. Mathematical programming is a privileged resolution approach, but efficiency highly depends on the strength of the considered mathematical models. This paper presents bound tightening and cut generation techniques to strengthen pump scheduling models. Numeric evaluations on both approximate and exact models show the benefit, if not the necessity, of such preprocessing
