Abstract
This paper describes an application developed for a major British Steel plant. It combines expert systems for process supervision with the on-line data acquisition system of the plant. The data from the plant is in a form of analogue and digital values. The diagnostics must reason about faults indicated by these values. A most important factor is that the faults are indicated by a time history, rather than immediate measurements. As a result, extensive facilities have been developed to abstract the time histories of these numeric values into a qualitative form usable by the expert system. This abstraction process from numerical histories to qualitative states is one of the essential activities in combining numeric and qualitative reasoning. The paper gives a description of the application and the numeric time history abstraction functionality.
