    1. Systems Modeling Language (SysML) Overview April 20, 2005

    2. SE Practices for Describing Systems Specifications Interface requirements System design Analysis & Trade-off Test plans

    3. Why Model Based Approach ? Improved communications Reduced ambiguity Reduced errors More complete representation Enhanced knowledge capture

    4. Unified Modeling Language (UML) UML Is a visual modeling language Is not a methodology Defacto standard for SW level OO modeling Visual Modeling Language = Notation + Semantics Semantics = meaning Notation = representation of meaning

    5. UML/SysML Status UML V2.0 Updated version of UML that offers significant capability for systems engineering over previous versions Adopted in June 2003/Finalized in 2005 UML for Systems Engineering (SE) RFP Established the requirements for a system modeling language Issued by the OMG in March 2003 SysML Industry Response to the UML for SE RFP Addresses most of the requirements in the RFP V1.0 expected to begin adoption in 2005

    6. SysML Partners Industry American Systems, BAE SYSTEMS, Boeing, Deere & Company, EADS Astrium, Eurostep, Israel Aircraft Industries, Lockheed Martin, Motorola, Northrop Grumman, oose.de, Raytheon, THALES Government DoD/OSD, NASA/JPL, NIST Vendors Artisan, Ceira, EmbeddedPlus, Gentleware, IBM, I-Logix, PivotPoint Technology, Popkin, Project Technology, 3SL, Telelogic, Vitech Liaisons/Other Organizations AP-233, CCSDS, EAST, INCOSE, Rosetta

    7. SysML Scope

    8. SysML Diagram Taxonomy

    9. A Few Sample Diagrams

    10. Assemblies, Parts, Ports, Connectors & Flows

    11. Continuous Systems

    12. Sequence Diagram with Reference

    13. State Machine Diagram

    14. Requirement Diagram Showing Requirements Flowdown

    15. Related Standards Efforts

    16. Standard UML Profile for DoDAF Recent initiative started through the OMG Purpose Develop standard representations of DoDAF products using UML/SysML Benefits Improved communications Architecture model reuse and maintainability Model interoperability among tools OMG Timeline Plan to issue req’ts for the standard in late ’05 or early ‘06

    17. SysML / AP-233 Alignment

    18. Systems Engineering Standards & Architecture Frameworks

    19. Summary SysML is a general purpose language that supports the specification, analysis, design, & verification of complex systems SysML is being developed in conjunction with related systems engineering and architecture framework standards Part of the OMG Model Driven Architecture Standards ISO AP-233 data interchange standard UML Profile for DoDAF initiative Planned adoption of SysML v1.0 to begin end of 2005
