Resumen
The article discusses issues related to the national standards of the digital railway in the UK. Digital railway technologies require higher levels of integration in railway systems and railway operations, as well as between real-time management systems and IT business systems. Unlike conventional signaling systems, digital signaling systems are deployed on rolling stock, track infrastructure and operational centers associated with scheduling systems, which necessitates new ways of working that are not currently implemented by the UK railways. The ontological approach of the system of systems, which changes the accepted standards, becomes the central link in the creation and operation of this new digital railway. A system of systems is a set of targets or dedicated systems that combine their resources and capabilities together to create a new, more complex system that offers more functionality and performance than just the sum of composite systems. At present, systems of systems are a critical research and practical discipline for which reference systems, thought processes, quantitative analysis, tools, and design methods are incomplete. The methodology for identifying, abstracting, modeling, and analyzing system problems is commonly called a system design system.
