3 Agenda  What is SysML? Relationship between UML and SysML Examples of Extensions Industrial Control Concluding Remarks

4 What is SysML? A graphical modeling language in response to the UML for Systems Engineering RFP developed by the OMG, INCOSE, and AP233  a UML Profile that represents a subset of UML 2 with extensions Supports the specification, analysis, design, verification and validation of systems that include hardware, software, data, personnel, procedures, and facilities Supports model and data interchange via XMI and the evolving AP233 standard (in-process) SysML is a Critical Enabler for Model Driven SE

5 SysML Background UML for System Engineering RFP issued – 28 March 2003 SysML Partners Kickoff meeting – 6 May 2003  Chaired by S. Friedenthal and C.

10 Agenda What is SysML?  Relationship between UML and SysML Examples of Extensions Industrial Control Concluding Remarks

11 Relationship Between SysML and UML UML4SysML SysML Profile

12 SysML Diagram Taxonomy

13 Major Extensions to UML 2 New Diagram Types  Requirement Diagram (visual modeling of requirements)  Parametric Diagram (showing relations between parameters) Structure Diagram  Block Definition Diagram (based on UML class diagram with blocks instead of classes)  Internal Block Diagram (based on UML composite structure diagram with restrictions and extensions) Activity Diagram  extensions for continuous flow modeling  extensions to support disabling control and control operators.  accommodate needs of Extended Functional Flow Block Diagrams (EFFBDs)

14 Agenda What is SysML? Relationship between UML and SysML  Examples of Extensions Industrial Control Concluding Remarks

15 SysML Diagram Frames

16 Blocks are Basic Structural Elements

17 Block Definition Diagram

18 Internal Block Diagram

19 Internal Block Diagram Example Control signals

20 Requirements Diagram (NEW)

21 Parametric Diagram (NEW) Used to express constraints (equations) between value properties  Provides support for engineering analysis (e.g., performance, reliability) Constraint block captures equations  Expression language can be formal (e.g., MathML, OCL) or informal  Computational engine is defined by applicable analysis tool and not by SysML Parametric diagram represents the usage of the constraints in an analysis context  Binding of constraint usage to value properties of blocks (e.g., vehicle mass bound to F= m × a) Parametrics Enable Integration of Engineering Analysis with Design Models

22 Example: Defining Vehicle Dynamics

23 Example: Vehicle Dynamics Analysis – Parametric Diagram

24 Parametric Example - Usage Parametric Diagram

25 Activity Diagram Notation Flows can be discrete, streaming or control

26 SysML EFFBD Profile

27 Allocations Provides general relationship to map one model element to another Includes specific subclasses of allocation with constraints on their usage  Behavioral  Structural  Flow Explicit allocation of activities to swim lanes (e.g. activity partitions) Graphical and/or tabular representations

28 Different Allocation Representations Explicit Allocation of Activity to Swim Lane Allocate Relationship Callout Notation Compartment Notation

29 Example - SysML Allocation to SW and HW

32 Agenda What is SysML? Relationship between UML and SysML Examples of Extensions  Industrial Control Concluding Remarks

33 System Modeling

34 Combining Model-Driven and Model Based Design in Industrial Machine Control MDD: Model Driven Development in Rhapsody (Telelogic) MBD: Model Based Design in Simulink (Mathworks)

35 MDD versus MBD Feature Comparison Table 1. MDD versus MBD feature comparison

36 Complementary Tool Solution The Rhapsody MDD environment covers standard UML 2.0 / SysML based software and systems design Simulink is the de-facto standard for dynamic systems modeling  allowing block diagrams of complex dynamic (mathematical) algorithms to be captured and analyzed Simulink connection to Rhapsody

37 Rhapsody – Simulink Integration (1)

38 Rhapsody – Simulink Integration (2) Simulink Model and Code Imported into Rhapsody

39 Agenda What is SysML? Relationship between UML and SysML Examples of Extensions Industrial Control  Concluding Remarks

40 Concluding Remarks SysML contains many interesting extensions of UML It will be good to get a more common language between different disciplines Question is what kind of validation can be made with these different models  What about common semantics?  What about time connectivity between discrete event an continuous simulators?
