Abstract:	ESPM is an Expert System for Preventive Maintenance that provides the framework for application-specific equipment maintenance tools. The expert system for preventive maintenance and diagnosis was developed for the Aluminum Extrusion Press and Related Equipment. The system is built in VP-Expert and is implemented on a personal computer. The expert system includes many characteristics of an expert system cell because it can be expanded easily by adding new information to its knowledge base or by changing the existing information. The expert system can be connected directly with a PC system through a VP-Expert software package and can interact with C language, dBASE III plus and VP-Planner worksheet. The basic ideas behind this expert system are to provide a non-expert with the necessary information and correct machine parts location. The system then leads the non-expert through periodical maintenance in a very friendly enviroment. The main task of the expert system is to replace human expertise in maintenance processing and the preventive maintenance manuals of machine equipment with a very user-friendly personal computer enviroment. In addition, the system can take advantage of the user's accumulated experience to expand and modify the knowledge base of the expert system itself.
