Case study: Application of evolving architecture frameworks for heavy rail asset management and safety assurance
A heavy rail system is a complex system of systems that has specific challenges for asset management. The introduction of modern digital systems into existing rail systems adds further to this complexity. The Asset Standards Authority of Transport for New South Wales in Australia is introducing model-based systems engineering through the use of an architecture framework populated using the Systems Modeling Language (SysML), referred to hereafter as the Transport Network Architecture Framework (TNAF). The TNAF is intended initially to be used to act as a structure that will assist procurement through the depiction of the minimum standards to be met when specifying new systems to be acquired and integrated into the network. This article describes how architecture framework tools can be used for management of the various configurations.
