Abstract
AbstractThe replacement of the signalling and control systems on Sydney's critical heavy‐rail network infrastructure is envisaged to take years and affect many systems across the operational railway. Systems Engineering has been adopted early in the system lifecycle to manage the complexity and risks in a rigorous and consistent manner. This paper aims to document the real‐life application of a Model‐Based Systems Engineering (MBSE) methodology in the conceptual design stage on Transport for New South Wales’ Digital Systems Program. It illustrates how this methodology was applied to capture the operational and maintenance concepts, derive the architecture and interfaces and guide resulting requirements. It provides valuable lessons‐learnt for the acquiring organisation on the deployment of MBSE, its benefits and lessons learnt.
