Abstract: Pump scheduling is a key element in water distribution systems operation. Modeling this problem requires a mixed integer nonlinear program (MINLP) formulation. Even linearization schemes of mixed integer linear programs ...

Abstract: In water distribution systems, pumps are used for supplying water from low points to elevated tanks that supply the network’s demands. The pumps are operated in different ways that could be distinguished by the complexity ...

Abstract: The events of September 11, 2001 in the United States have brought to the fore the problem of drinking water distribution systems security. As a water distribution system is spatially diverse, limiting physical access to ...

Abstract: Deliberate contamination is generally viewed as the most serious potential terrorist threat to water systems. Chemical or biological agents could spread throughout a distribution system and result in sickness or death among ...

Abstract: A method for near-optimal real-time on-line operation of urban water distribution system is presented and demonstrated. It uses a reduced model (RM) of the network which reproduces its performance over time with high ...

Abstract: Red team–blue team exercises are methods of evaluating security by creating a “game” where one team (the red team) attempts to “attack” a target and the other team (the blue team) tries to defend it. This paper describes ...

Abstract: Looped water distribution system (WDS) repartitioning to district metering areas (DMAs) gained popularity as an effective technique to manage the system and detect and reduce system leakages. However, to apply this method ...

Abstract: The multiobjective optimization model described in this study is aimed at exploring the tradeoff between cost and resiliency for water distribution systems optimal design. Many have dealt previously with minimizing cost ...

Abstract: This work presents a model for the inclusion of chemical water stability in optimizing the operation of water distribution systems. When desalinated water is mixed with surface water and/or groundwater, the blend can become ...
