Abstract

As Expert Systems (ES) migrate from prototype to operational use, the tightly coupled issues of system maintenance and domain expansion become more significant. The manner in which an ES architecture and organization can support such key elements of domain expansion (and maintenance) as knowledge acquisition, representation, addition and modification are highlighted and illustrated using the Fault Isolation Expert System for TDRSS Applications (FIESTA). The paper focuses on domain expansion as applied to a diagnostic expert system, and considers implications for ongoing system maintenance, which encompasses automated end-user support.
