Abstract: A method and system is disclosed for maintaining a database of configurations of mechanical equipment. A functional configuration database is established to store functional information about an end item and internal components of the end item. A logical configuration database is established that corresponds to the functional configuration database. A physical configuration database is established to store physical information about the end item. An operational configuration database is established to store operational information about the end item. The database of configurations of mechanical equipment is maintained in accordance with the functional configuration database, the logical configuration database, the physical configuration database and the operational configuration database.

Abstract: A data processing system stores a first database of component data on components of an equipment. The data processing system stores a second database of maintenance personnel associated with corresponding qualifications. The data processing system associates at least one predictive maintenance factor (for a component) with the corresponding component data. A scheduler schedules maintenance for a maintenance time period for at least one of the components based on the first database, the second database, the associated predictive maintenance factor, and an elapsed time with respect to an installation date of at least one component. The predictive maintenance factor may be defined by one or more of the following: a longevity estimate, a probability of failure, a financial estimate on maintenance of a component.
