Threat Ensemble Vulnerability Assessment - Sensor Placement Optimization Tool (TEVA-SPOT) Graphical User Interface


U.S. EPA. Threat Ensemble Vulnerability Assessment - Sensor Placement Optimization Tool (TEVA-SPOT) Graphical User Interface. U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-13/014, 2013.


TEVA-SPOT is used by water utilities to optimize the number and location of contamination detection sensors so that economic and/or public health consequences are minimized. TEVA-SPOT is interactive, allowing a user to specify the minimization objective (e.g., the number of people exposed, the time to detection, or the extent of pipe length contaminated). It also allows a user to specify constraints. For example, a TEVA-SPOT user can employ expert knowledge during the design process by identifying either existing or unfeasible sensor locations. Installation and maintenance costs for sensor placement can also be factored into the analysis. Python and Java are required to run TEVA-SPOT
