Formalization of a Product-Process-Resource Model within Aircraft Component Maintenance, Repair, and Overhaul

Maintenance, Repair and Overhaul (MRO) of aircraft components is a complex and critical process with high product and process variability. To ensure the safety and reliability of aircraft, it is crucial to have accurate and up-todate information about components throughout their lifecycle. However, this information is often scattered across various systems and stakeholders, resulting in data fragmentation and inconsistency. Data integration is needed to create a unified and comprehensive view of the components lifecycle. The Product-Process-Resource (PPR) modeling framework is a cross-industry framework that provides a comprehensive view of the various dimensions involved. The framework is applied to the MRO service provider domain. This paper explores the use of standards and norms to formalize an information model based on the PPR approach to improve data integration and ensure a high level of reuse. The proposed model integrates several community-maintained standards such as VDI/VDE 3682, EASA Part 145, EASA Part M, DIN 13306, DIN EN 61512, and IATA's ONE Record to provide a standardized and consistent representation of component MRO data.
