Global competition has been leading to more complex production systems, in which satisfactory maintenance is crucial for the operations. The ability to properly forecast failures, provided by Intelligent Maintenance Systems (IMS) can avoid downtimes and provide a competitive advantage. Moreover, it can also enable more precise demand planning in Spare Parts Supply Chain (SPSC), resulting in the availability of parts and services when they are necessary in shop floor, avoiding breakdowns and production interruptions. The proper integration of IMS and SPSC is of utmost importance to achieve these results. Some of the challenges related to this integration refer to semantic differences between these areas with diverse concepts and vocabulary. This work intends to propose the building of an ontology to overcome these difficulties by providing a common vocabulary and proper semantic integration of the areas, as a basis for the construction of a future integration information system to integrate IMS and SPSC.
