Abstract
This paper describes an attempt to develop a structural maintenance support expert system using videotex. Graphic data needed for maintenance support are much too diversified and further, the way to utilize them differs from user to user, so a prototype system permitting each user to utilize graphic data in his own respective way was developed in an attempt to establish the methodology. It was made clear that the NAPLPS videotex system seems to be one of the most favorable candidates for this purpose since it is easily accessed by a network and a large reduction of computer memory is attainable, which will enable the use of a microcomputer. Thus, the integration of videotex and an expert system will provide a maintenance engineer with a most flexible and versatile graphic data base.
