Team Icarus created a digital engineering case study based on an unmanned underwater vehicle (UUV) to provide a robust view of developing an architecture using Cameo Systems Modeler by executing the MagicGrid architecture development methodology. The case study includes connecting this architecture model to directly drive several engineering analysis tools (Excel, MATLAB/Simulink, a Computer Aided Design tool) through middle-ware software (ModelCenter MBSE). The design was refined through a design of experiments and is visualized through software tools (ModelCenter Explore). This case study is provided to Naval Surface Warfare Center–Port Hueneme Division (NSWC PHD) to be a supplement to the training of systems engineers and systems logisticians to fill in the gaps of existing trainings. This case study is also provided to Naval Postgraduate School to supplement the education of current and future students on architecture development and digital engineering.Civilian, Department of the NavyCivilian, Department of the NavyCivilian, Department of the NavyCivilian, Department of the NavyCivilian, Department of the NavyCivilian, Department of the NavyApproved for public release.
