Applying SysML to Analyze and Design Large Complex Systems

John Watson
Principal Member Engineering Staff
Lockheed Martin
Moorestown, New Jersey

Presentation: ppt


This presentation will share with you our experiences at using SysML to create a model-based approach for developing large complex systems. This methodology includes processes and techniques for decomposing a system and deriving various system architectural static and dynamic system perspectives including the system’s behavior, structure and requirements.

This presentation will also show how a system can be represented at various abstraction layers such as the System of Systems level, a System of interest level and a Subsystem level. At each of these levels a model is produced to decompose the system and present a set of specifications to drive lower layer models.

Performance results are established at each level of system decomposition and abstraction. Information from the models is used to build and execute simulations of the architecture. The simulation results are used to validate the architecture at each level and fed-back to produce improved deployment views, structural views, and influence other levels of system decomposition. These techniques permit the architect to predict, build, measure and improve the system design through various iterative development cycles from conception to completion.

The INCOSE Space Systems Working Group MBSE Grand Challenge Team and MBSE at JPL

Chris Delp
Software Test Engineer
Integrated Ground Data System
Integration Test and Deployment
Pasadena, California

Presentation: ppt


The INCOSE Space Systems Working Group has accepted the Grand Challenge to forge a path for adoption and exploitation of Model-Based Systems Engineering (MBSE) as applied to Space Systems. Our team is prototyping a space systems MBSE process by developing an integrated model around an example captured in the classic book Space Mission Analysis and Design (SMAD), Third Edition, by Wiley J. Larson and James R. Wertz (editors). The example is called FireSat; a mission designed to identify, detect and monitor forest fires from earth orbit. The mission provides a modeling project that is as challenging as any funded Earth mission. This document-based example sets the stage for demonstrating how a model can add significantly to the specification and visualization of a Space System. SysML is one of the technologies we are exploring in this testbed.

NASA JPL has taken a lead role in the Space Systems team as part of the Lab’s commitment to advancing Model-Based Systems Engineering. JPL-developed State Analysis brings the challenge of coordinating multiple model development methods and artifacts to strengthen the role of software system architecture in the larger system model.

Deployment of SysML in Tools and Architectures: An Industry Perspective

Rick Steiner
Raytheon Integrated Defense Systems
San Diego, California

Presentation: ppt


Systems modeling tools have rapidly adopted the SysML specification, but with varying degrees of completeness and conformity. The deployment of a given system modeling tool for system architecture development must balance the constraints of the architecting method & framework used with the inherent SysML capabilities of the tool. This presentation will provide an industry based user's view of a few specific tools, and their applicability to enterprise level, mission level, logical level, and implementation level architectures. Three specific tools will be examined, using a common simple example to illustrate differences in implementation. Issues related to deploying these tools in an industrial setting for distributed, collaborative architecture development will also be discussed.

About the speaker:

He has served as chief engineer, architect, or lead system modeler for several large scale electronics programs, incorporating the practical application of the Object-Oriented Systems Engineering Method (OOSEM), and generation of Department of Defense Architecture Framework (DoDAF) artifacts from complex system models.

Mr. Steiner has been a key contributor to the original requirements for SysML, and also the development of SysML specification. His main contribution to this specification has been in the area of allocations, sample problems, and in updates to requirements. Mr. Steiner has provided frequent tutorials and presentations on SysML and model driven system development at INCOSE symposia and meetings, NDIA conferences, and internal to Raytheon.


SysML Parametrics and Progress Towards Multi-Solvers and Next-Generation Object-Oriented Spreadsheets

Dirk Zwemer, President
Manas Bajaj, Senior Research Engineer
Atlanta, Georgia

Presentation: ppt


Collaborative modeling and simulation of complex systems requires a framework that provides both integration and control of multiple analysis models, databases, and design tools. A parametric solver based on SysML is presented as an initial example of such a framework, and sample models both inside and outside the domain of systems engineering are presented. These capabilities are based on technology licensed from Georgia Tech, including composable object (COB) technology from Russell Peak 's research group, that is being commercialized via the VentureLab incubator program .

The examples presented here include modeling operational capabilities of an unmanned aerial vehicle and multi-year corporate financial projections. The demonstrations show that SysML has strong potential as a modeling interface for systems-level visualization and design-analysis integration. It is powerful, flexible, easy-to-learn, and offers enhanced modularity and reusability. An important area for extension is the use of a spreadsheet-based perspective to complement the basic diagrammatic SysML notation, especially for organizations with large amounts of instance data.

In this panel we will explore how PLM/CAD/CAE/CAM and MBSE are related and their envisioned convergence. Panelists will cover topics including:

  1. Describe some of your more interesting customer applications that combine MBSE-PLM/CAX today.
  2. What is your vision for advancing the MBSE-PLM/CAX combination? What role do you see SysML playing in your MBSE-PLM/CAX vision?
  3. What are challenges/barriers towards achieving this vision vs. where industry is at today?
  4. Describe the main actions the community as a whole needs to take to facilitate reaching this vision. For example, what things do end users, vendors, standards bodies, and academia need to do?
  5. By way of comparison, product shape representation took some 20+ years to shift from a documentation-based approach (2D drafting on physical media) to a full model-based approach (3D computer-based models, including features and parametrics). This involved the development and implementation of new concepts and processes—not just digitizing the traditional drafting process.
    1. How long will systems engineering take to do the same (i.e. to move from document-based SE to MBSE)?
    2. In what respects is the journey towards MBSE similar (e.g., what shape representation/CAD evolution lessons can be applied toward MBSE)? What is different?
    3. What are key milestones along this path, and where are we now?

This panel will overview where OMG SysML™ is at today and explore where it is going from a tool vendor perspective. Panelists will address topics and questions such as:

  1. How would you characterize the MBSE market in general and your SysML customers / target audience in particular?
  2. Describe some of your more interesting customer applications of SysML. What SysML constructs are they are using the most thus far?
  3. What feedback are you receiving about SysML from your customers? Positive aspects? Issues and concerns? Do any of these involve research-oriented issues that academia needs to address?
  4. Identify key needs to accelerate the deployment and usage of OMG SysML 1.0 across industry and government. Can some of these can be addressed in collaborative forums (such as INCOSE, OMG, NIST PlugFest, open workshops, and so on), or what do you recommend?
  5. How well do you think OMG SysML 1.0 covers what is needed for MBSE? Are there any key gaps?
  6. Though initiated by systems engineers, SysML is a general-purpose “systems modeling language” that need not be necessarily restricted to the conventional systems engineering domain. What other domains have you seen it applied to, and/or what domains do you envision?
