The Expert Interface software program aids the novice user in choosing
the correct release scenario and specifying the inputs required by th
e EPA Industrial Source Complex (ISC) air dispersion model. This innov
ative system provides a framework so that users follow consistent meth
odologies for modeling various release scenarios. This is achieved thr
ough the use of a graphical interface that includes a query methodolog
y enabling the program to identify the release scenario and ask approp
riate questions for more details. In this paper we describe the design
, implementation, capabilities and use of the Expert Interface for Sup
erfund applications. The Expert Interface program is written in Micros
oft Visual C++ for the Windows environment. For illustration purposes,
this phase of the development considers two source categories. The ge
neric source category consists of a point source, while the Superfund
category includes a lagoon source. For each source type the program qu
eries the relevant variables from the user. In addition, the Expert In
terface asks questions regarding control options, receptors, meteorolo
gy and output formats. The Expert Interface then creates the input fil
e required by the ISC dispersion model. Finally, the Expert Interface
enables the user to run the ISC model and browse the results file.
