Abstract

The field of Reliability, Availability, Maintainability, and Safety (RAMS) analysis traditionally adheres to principles established mainly for space-based systems. However, in the pursuit of optimizing RAMS for our specific system, Phasing and Diagnostic Station (PDS), developed for ESO-ELT, it has become imperative to introduce deliberate deviations from these conventions. This presentation aims to elucidate the practicality and underlying rationale for these strategic deviations, shedding light on the advantageous outcomes they yield for our system's performance. The primary focus will be on redefining RAMS requirements tailored to our system's unique characteristics and operational challenges. We intend to engage in a constructive dialogue with the audience, emphasizing the importance of optimizing these requirements to align seamlessly with the distinctive needs of our system. Furthermore, we will delve into the critical aspect of obsolescence planning, which directly stems from the concepts of availability and maintainability within RAMS. This planning is crucial for ensuring our system's longevity and continued operational excellence.
