Model-Based Systems Engineering Using SysML_SUM
10/27/2009
Systems engineering is transitioning from a document-based approach to a model-based approach. With model-based systems engineering (MBSE), emphasis is placed on defining, managing, and controlling a coherent model of the system that can then be reflected in systems engineering documentation covering specifications, interface controls, system design, trade studies, and analysis reports. This report provides an overview of the benefits of model-based systems engineering over a document-based approach. It also highlights how OMG SysML&trade supports MBSE to flow down requirements from the mission level to the system design and to the hardware and software components. Several of the lessons learned from early applications of MBSE using SysML are also covered.
This report is based on Sanford Friedenthal's presentation at PLM Road Map&trade 2009.
