Abstract

This paper formulates the security problem in critical water infrastructure systems for diagnosing quality faults. The proposed scheme is based on the discretized equations of advection and reaction of contaminant concentrations in pipes and tanks, expressed in a state-space form. Faults are signals affecting the states, and their impact is measured based on certain epidemiological dynamics. A multi-objective optimization problem is formulated for minimizing various risk-related objectives.
