Study of Executable Model Based Systems Engineering from DODAF Using Simulink.

摘要

Diagrams and visuals often cannot adequately capture a complex system's architecture for analysis. The Department of Defense Architectural Framework (DoDAF), written to follow the Unified Modeling Language (UML), is a collection of mandated common architectural products for interoperability among the DoD components. In this study, DoDAF products from as-is Remotely Piloted Aircraft (RPA) Satellite Communication (SATCOM) systems have been utilized for the creation of executable architectures as part of an Executable Model Based Systems Engineering (EMBSE) process. EMBSE was achieved using Simulink, a software tool for modeling, simulating and analyzing dynamic systems. This study has demonstrated that DoDAF products can be created and executed following the rules of UML for analysis. It has also shown that DoDAF products can be utilized to build analysis models. Furthermore, these analysis models and executable architectures have been presented to a panel of experts on the topic. The comments and study results show a desire for executable architectures as well as their viability as presented in Simulink. This study concludes there is a need, a use and a method to implement objective analysis using EMBSE from DoDAF products in Simulink for current and future DoD systems.
