Digital Engineering of Large Scale System of Systems: End-to-End (E2E) Modeling and Analysis Environment

The US Department of Defense (DoD) has increasingly expanded their focus beyond systems to address the application of systems engineering approaches to 'missions'. Mission Engineering (ME) is defined in the Defense Acquisition Guidebook as: "the deliberate planning, analyzing, organizing, and integrating of current and emerging operational and system capabilities to achieve desired operational mission effects". At the same time, in the DoD Digital Engineering Strategy, the DoD has emphasized the transformation of systems engineering into a digital, model-based discipline. Bringing these two together, there is strong interest in the development and application of Digital Engineering Environments (DEE) to address mission level systems of systems (SoS) requirements, analysis, engineering, and portfolio management. This paper provides an approach to applying Digital Engineering (DE) to a large system of systems mission [1].
