Abstract :
Most real world problems contain complex and various constraints, and this goes for the sewerage system control problem, our target. For handling them, the penalty depending on the degree of violation is often used. However, additive penalty method (APM) often leads the fatal compromise to a local optimum, in this paper we introduce independent constraint satisfaction (ICS). Another difficulty of this problem is the inaccuracy of inflow forecasting, we show the eager re-scheduling is superior to the lazy one.
