Do Obsolescence and Shortages have an impact on Reliability, Maintainability and Availability?

Year: 2024

Type: article

Abstract: The classic concepts of reliability, maintainability and availability (RAM) are well established, but their link with obsolescence and shortages in today’s industrial context remains poorly explored. This paper proposes an exploratory study to model the standard definitions of RAM and relate them to obsolescence and shortages, extending their scope beyond the usual physical and software components. Our initial results suggest that failure to take these phenomena into account systematically leads to an overestimate of availability. Research avenues are presented to quantify these overestimates.
