ABSTRACT
The status quo of control in water distribution networks (WDN) relies on simple, rule-based control strategies to operate pumps and valves. For example, pumps are switched on/off if a tank's water level---a local measurement---is below/above a certain threshold. As an alternative to localized, rule-based control, network-driven control that utilize WDN topology and measurements can be beneficial.
Unfortunately, network-driven control of WDNs is very difficult as hydraulic models are nonconvex, valve and pump models form non-trivial, combinatorial logic, and water demand patterns are uncertain. Prior research on control of WDNs addressed major research challenges, yet mostly adopted simplified hydraulic models, WDN topologies, and rudimentary valve/pump modeling. This Work-in-Progress showcases the potential of network-driven control of WDNs. The proposed approach amounts to solving a series of convex optimization problems that graciously scale to large networks. Simple case studies are included showcasing early results, and applications of the proposed optimization methods to other WDN applications are discussed.

ICBBB '18: Proceedings of the 2018 8th International Conference on Bioscience, Biochemistry and BioinformaticsSea is the estuary of rivers on land. In the sea all kind of pollutions carried by the river flow will be accumuated, which make the sea water quality worse than the river itself. Comal river and Garang river is two of the few river that flows into the ...
