BlueM.MPC is a software for the simulation of model predictive control (MPC) in sewer networks. MPC is an online strategy for real time control (RTC). Control decisions are calculated during operation with a process model and optimization algorithms. This feature distinguishes MPC from off-line control strategies, in which the control decisions are calculated during the design phase. These control decisions are usually stored in a database (rule-based control) and are available during operation without delay. BlueM.MPC implements SWMM5 for process modelling and BlueM.Opt for optimization.
