Abstract
The reliability of industrial systems is challenged by the increasing use of digital technology. One of these challenges is the
reliability of digital technology (IT) in combination with physical assets (OT) - so-called ‘IT/OT’ converged systems or digitized
systems. To ensure the reliability of physical assets, RAMS (Reliability, Availability, Maintainability, and Safety) methodology
has become a widely accepted approach for designing and evaluating their performance. Unfortunately, the RAMS method is
less common and evaluated in the context of digitized systems. This research discusses the application of a five-step RAMS
method within the context of digitized systems. The outcomes of this RAMS method on a traditional system and a digitized
system are compared using a real case study carried out with the main Dutch railway operator. The case study shows that the
current RAMS application processes should be adapted for use on digitized systems. Several design principles are presented
which can guide the better application of RAMS within a digitized environment.
