A tool system for knowledge-based on-line diagnosis in industrial automation

Abstract

A tool system which supports the development of expert systems for use in the field of industrial automation is presented. The knowledge representation language provided by the tool system supports different aspects of knowledge which are important in this domain: the representation of declarative and procedural knowledge; the representation of temporal knowledge; and the representation of knowledge about real-time behavior. As a further part of the tool system, an expert system compiler with the ability to transform expert systems into a conventional procedural program (realized in C) is described. This method allows a simple integration of knowledge-based techniques into conventional software systems.<>
