EMADVANTAGE supports hazard modeling. The architecture integrates hazard models with GIS displays. It also assists in making a protective action decision that is based on the time a potential hazard may impact a response zone or designated facility. Current models include heavy gas dispersion, jet fire, pool fire, flash fire, explosion (with overpressure and debris estimates), and water-borne spills. An example of how site-defined models may be integrated into EMADVANTAGE is provided in Figures 1 and 2.

Figure 2. Model Integration: GIS

In order to integrate a new model into EMADVANTAGE, we work with the client to identify the model, the user-oriented interface needed to provide inputs, how the model will graphically and textually display results, and finally how the model will be used in the clients decision making process.

The result of modeling is a Threat Area, which is a geographic region depicting the area that will likely be impacted by the potential hazard.

EMADVANTAGE's general hazard component allows a user to loosely-couple a model with its architecture by a direct link to the model from the EMADVANTAGE interface.
