Optimal And Objective Placement Of Sensors In Water Distribution Systems Using Information Theory, Mohammad S. Khorshidi, Mohammad Reza Nikoo, Mojtaba Sadegh

Civil Engineering Faculty Publications and Presentations

Optimization-based deployment of contamination warning system in water distribution systems has been widely used in the literature, due to their superior performance compared to rule- and opinion-based approaches. However, optimization techniques impose an excessive computational burden, which in turn is compensated for by shrinking the problem’s decision space and/or using faster optimization algorithms with less accuracy. This imposes subjectivity in interpretation of the system and associated risks, and undermines model’s accuracy by not exploring the entire feasible space. We propose a framework that uses information theoretic techniques, including value of information and transinformation entropy, for optimal sensor placement. This can …
