UAF Tool Vendor Roadshow (Dec 2022) - IBM Rhapsody

The UAF is the latest modeling specification for systems of systems (SoS) modeling. It is designed to cover all the viewpoints from the latest defense architecture frameworks, namely DoDAF, MoDAF, NAF and others. The UAF is a very rich specification with several layers (domains) and aspects (“model kinds”) and while it is very rich and expressive, how to apply it in a real-life context can be quite challenging. One challenge is how to translate concepts of operation, existing and future capabilities, planning and acquisition strategy into a concrete UAF model. Another challenge is how to properly use the various levels of abstractions across its domains to enable reuse across different concrete realizations. Yet another challenge is that UAF does not exist in isolation and needs to be integrated with a broader set of lifecycle tools, such as requirement tools, system models in SysML, planning tools, simulation tools and others. In this demo, we describe how we transform conops documents and requirements into an actual UAF model using an emergency response system, which is a SoS. We demonstrate how the various UAF aspects are modeled, how the UAF modeling environment is integrated with a requirements management system, how the UAF technical views are integrated and transformed into SysML system models, and how roadmaps and plans are integrated with planning tools. We will also show how behavioral aspects of the SoS UAF models are simulated to validate them and reason about the behavior of the overall SoS. The overview will include demonstrations using an actual set of tools typically used in engineering environments.
