Conclusion
In-Service Support and Obsolescence Management - A necessary symbiosis

The shortage of electronic components and, more broadly, of materials, and the obsolescence of software, technologies, regulations and national or international standards, present all players in the value chain with serious challenges. This can automatically lead to reduced availability of major civil and military infrastructures, assets (manufacturing plants, power stations...) or equipment/systems (aircraft, trains, vehicles...) through the impossibility of maintaining systems. Repeated crises and various instabilities amplify the unavailability of systems and fleets of systems.

It is in this sense that, today more than ever, the links that can exist between the management of shortages and obsolescence and the technical and logistical support activities of operational maintenance are modeled and argued in this article.
