micro-UNIXPERT : Ein wissensbasiertes System zur Behandlung von Problemen bei UNIX-Druckauftraegen

Abstract

micro-UNIXPERT (UNIX^ - PERiphery - Tester) is an interactive, knowledge-based diagnosis system for the treatment of printer hardware faults and of other problems which can appear in connection with printing (user errors and software faults). If possible, the system both generates diagnoses and gives proposals for clearing. The entire knowledge of micro-UNIXPERT consists of a set of PROLOG-like facts and rules. The system is implemented in LISPLOG, a LISP/PROLOG integration running in FRANZ LISP under the UNIX 4.2 BSD operating system on a VAX 11/750. After a general introduction into the problems of diagnosis systems and a discussion of the most important micro-UNIXPERT features (knowledge acquisition, positive and negative facts, user acceptance, inference mechanism), the method of operation of the system is explained by giving full details of the LISPLOG implementation. -------------- ^ UNIX is a registered trade-mark of Bell Laboratories
