Model Based Systems Engineering (MBSE) Process Using SysML
for Architecture Design, Simulation and Visualization

Verification and Validation of systems designs are difficult because the stakeholders’ (e.g., owners, users, and developers) perception may differ from the architects’ views. Thus there needs to be a solution that allows the stakeholders and the architect to verify that the design meets the requirements documented and the system capabilities are designed as the stakeholder expected. The architectural design is supported by a Graphical User Interface which the stakeholder can use to approve the design before implementation. The IBM Rational Rhapsody modeling tool is used with supports of SysML and the Harmony for Systems Engineering Process in the development of system architectural designs. The IBM Harmony Process provides process guidance and a SE Toolkit that implements automated generation of diagrams and helps enforce traceability between the diagrams. These executable scenarios are then used to drive a Java interfaced GUI for the architecture visualization.

Mr. Osvalds supports large government transformation programs with systems engineering and architecture tasks, including planning, implementation and reviews of architectural products, and processes for architectural design and modeling. Mr. Osvalds has used and supported the DoDAF and OMB FEA architecture frameworks for the Federal Government and DoD communities. Currently Mr. Osvalds is developing Model Driven Systems Engineering techniques and tools for use in large systems.

Mr. Gundars Osvalds is the new President-Elect for the INCOSE Chesapeake Chapter for 2011.
