RAM4S (Reliability, Availability, Maintainability, Safety, Security, Supportability and Sustainability) characteristics for a railway system can be described as the confidence with which it can guarantee the achievement of an agreed volume of traffic with defined quality in a given period. With increase in performance demands from governments, infrastructure managers and train operators are under pressure, to enhance the RAMS characteristics of their operating systems. As a result, during the last 10 years, RAMS issues have become critical for competitiveness and economic viability of the railway systems all over the world.
Currently, JVTC is engaged in projects which have direct or indirect focus on RAMS analysis. Some of these projects are within the framework EU H2020 Program and JVTC is one of the key players for the analysis of RAMS of railway systems.
