The US Department of Defense (DoD) Architecture Framework (DoDAF) provides a common approach for architecture description development. The primary use of DoDAF is capability development and system acquisition in the military domain. Although DoDAF was not designed to support the development of simulation environments, many of the artifacts necessary to produce and document such simulation environments can be described by the architecture models in this framework. This paper examines the application of the DoDAF and the related systems engineering concepts within IEEE 1730-2010 Distributed Simulation Engineering and Execution Process (DSEEP), a recommended practice for the engineering and execution of a distributed simulation environment. This paper uses the Unified Profile for DoDAF and MODAF (UPDM) for the construction of architecture models. UPDM is a UML profile of the Object Management Group (OMG) that provides a modeling standard for both DoDAF and MODAF. This paper builds on an earlier SISO paper on architecture description development (04F-SIW-015: The Application of the DoDAF within the HLA Federation Development Process), which was based on DoDAF 1.5. This paper adds amongst others new DoDAF 2.0 viewpoints, provides additional examples of models, uses UPDM for model construction, and references the DSEEP as engineering process.
