Abstract
SUMMARY & CONCLUSIONSModel-Based Systems Engineering (MBSE) is a core technology in facilitating the digital transformation initiatives led by industry and defence governing bodies worldwide, where a prerequisite is the development of a "Digital Twin" (DT) of a given system asset. The definition of a DT and the corresponding mathematical and qualitative abstractions have been broadly defined within recent literature, however, in the context of the RAMS domain, a Digital Risk Twin (DRT) that can capture functional dependencies and their relationship to physical failures is necessary to digitally transform the RAMS domain. In this paper we formally introduce the concept of a Digital Availability Twin (DAT) - that will support a feedback loop for operational data to contextualize the dependencies identified by the DRT and enable the tailoring of baseline risk mitigation strategies such as maintenance policies and related sustainment activities, ensuring the required functions for a given set of missions is available for a corresponding asset fleet in an optimal manner and turn, enabling more agile risk mitigation when preparing for a specific mission condition.
