“…Since systems consist of interdependent components, the quantification of the impact of component-level decision making on the sustainability performance of systems is not an easy task. RAM analysis based on Monte Carlo simulation has been applied in different domains to convert component-level indicators to systemlevel indicators in order to support maintenance decision making (e.g., railways [36], manufacturing [37], data centers [38], and electromechanical systems [39], amongst others). In RAM analysis, the reliability and maintainability of components are utilized to assess the system availability [40].…”

Maintenance is becoming an increasingly green process, aiming to simultaneously minimize the impact of assets on the economy, society, and the surrounding environment while also mitigating any adverse consequences arising from maintenance activities. To manage maintenance from a sustainable perspective, appropriate indices able to represent environmental assessment results in an aggregated and synthetic way are necessary, along with rational decision-making tools able to simulate different maintenance alternatives considering various sustainability dimensions. In response to this challenge, a methodology rooted in sustainability indices and RAM analysis is proposed to support decision making with respect to sustainable maintenance practices. By applying the proposed methodology to a proof of concept we demonstrate that the approach enables the evaluation of both the environmental and economic impacts of different maintenance activities. Furthermore, the methodology facilitates the identification of specific environmental dimensions that need improvement, in addition to discerning the distinct contributions of individual components to the environmental and economic impacts at the system level. These insights offer valuable information to support informed decision making regarding the allocation of internal resources for impact mitigation. The obtained results underscore the potential applicability of this approach to industrial systems, signifying its contribution to the goal of achieving sustainable maintenance practices.

“…Furthermore, a literature review by Pirbhulal (2021) shows, that for RAMS there is a need to develop tools or methods for RAMS in specific applications in line with this Muhammed Nor et al (2022) state that a widely applicable RAMS methodology for the railway industry is currently missing.…”

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.
