TEVA-SPOT Toolkit

The Threat Ensemble Vulnerability Assessment and Sensor Placement Optimization Tool (TEVA-SPOT) has been developed by the U. S. Environmental Protection Agency, Sandia National Laboratories, Argonne National Laboratory, and the University of Cincinnati to support the design of contamination warning systems. The TEVA-SPOT Toolkit provides command-line interfaces to computational tools that compute impacts for contamination incidents and optimize sensor locations in a water distribution system. The TEVA-SPOT Toolkit supports a flexible decision framework for sensor placement that involves two major steps: a modeling process and a decision-making process. The modeling process includes (1) describing sensor characteristics, (2) defining the design basis threat, (3) selecting impact measures for design, (4) planning utility response to sensor detection, and (5) identifying feasible sensor locations.
