This report describes an expert system, ASSISTANT, that is written in Lisp and runs on a Symbolics 3610 but invokes numerical codes written in FORTRAN on a MicroVAX II. It is the result of a project whose purpose was to investigate and develop an expert system that can reduce the amount of the human expert's time required to process sensor data and that can be used to determine a more optimal sensor system. The focus was on the concept of a hybrid expert system. An expert system is a well known technique from the field of artificial intelligence that tries to capture human expertise in computer software. The term hybrid is used to imply the coupling of this technique to direct the more traditional numerical techniques of signal analysis. An exemplary task, the evaluation of seismic array data to determine optimal array configurations for nuclear test ban treaty applications, was selected in order to develop this concept. The array configurations analysis proved to be a very appropriate application and has lead to a powerful concept for an expert system that manages and assists in the parametric analysis of numerical databases. 11 refs., 5 figs.
