TEVA-SPOT_user_manual_2.5.2.pdf Initial commit Jul 24, 2019


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. TEVA-SPOT allows a user to specify a wide range of modeling inputs and performance objectives for contamination warning system design. Further, TEVA-SPOT 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 the CWS, (4) planning utility response to sensor detection, and (5) identifying feasible sensor locations.

The capabilities of TEVA-SPOT can be accessed either with a GUI or from command-line tools. This software is the TEVA-SPOT Toolkit, which contains these command-line tools. The TEVA-SPOT Toolkit can be used within either a MS Windows DOS shell or any standard Unix shell (e.g. the Bash shell).

TEVA-SPOT was developed between 2005 and 2011. The repository is no longer under active development. Version 2.5.2 is the final release. Related projects include:


TEVA-SPOT 2.5.2 can be installed using the zip file.
