The large observatories maintenance management: tools and strategies for maintenance manuals preparation

Large Observatories require enormous efforts in preparing the Maintenance Manuals. The possibility to adopt a standardised system, associated to centralized data base and software tools is investigated. This strategy implies a revolution of Maintenance Manuals: from information collection (paper-based), to a modular approach where data modules are used. The initial efforts associated to data modules preparation is compensated by several benefits (time savings for end-users, reduced training requirements, reduced equipment down-time). Moreover, cost savings in the preparation process, even for different equipment, is also possible. Finally, this standardised strategy will assure compatibility between different programs or partners.
