Telescope Modeling Challenge Team


In an effort to further promote the INCOSE/OMG Model-Based Systems Engineering (MBSE) Initiative, a next generation Telescope Modeling Challenge Team has been convened to investigate the applicability of MBSE to specifying, analyzing, designing, and verifying systems in the telescope domain. As part of the INCOSE SE Transformation, a strategic objective is to accelerate the transformation of systems engineering to a model-based discipline. The Telescope Modeling Challenge Team is driven to accomplish this goal by studying how telescope models interact throughout the system life cycle to best achieve the desired science cases set forth by stakeholders, while enabling the highest engineering capabilities to model real-world solutions.

In 2007, the European Southern Observatory (ESO) and the German Chapter of INCOSE (GfSE) joined to form the first generation Telescope MBSE Challenge Team, SE2. Their work can be found here: Telescope Modeling Challenge Team SE2. The second generation Telescope Modeling Challenge Team expands on the work and efforts from SE2.

Measure of Success

Our team will produce a new revision to the Cookbook for MBSE with SysML to provide system modelers with recipes and best practices for common modeling problems. Success of this Cookbook will be seen in the adoption of MBSE across the telescope community, including increased MBSE collaboration across projects and a trend toward organizational adoption of MBSE methods, as well as its utility to accelerate the development of telescope systems in varying stages of the system life cycle. System modelers will be able to make their models available for use across multiple domains, and their effectiveness will be measured by user feedback and system development improvements. Success will also be measured by examples of SysML challenges and lessons learned applied to real projects, as well as tool enhancements and improved ROI demonstrated by the use of these MBSE tools.

MBSE Challenge Goals

SysML is a graphical modeling language that provides semantics and notation (meaning and representations) to support the specifications, analysis, design, verification, and validation of complex systems. SysML is not a tool or methodology. The language is intended to support the specification and architecture of systems , and like many formal or informal languages it can be represented and applied in many different ways.

The next generation Telescope Modeling Challenge Team will continue to use SysML to facilitate the application of MBSE to systems engineering practices.

Primary goals for the Telescope Modeling Challenge Team are to:

  • Provide examples of SysML common modeling problems and best resolution approaches
  • Demonstrate that SysML is an effective means to support requirements engineering and management of complex systems throughout the development life cycle
  • Demonstrate the benefits of SysML models as the basis for integrated engineering and analyses

The new revision of the Cookbook for MBSE with SysML will provide the latest updates to MBSE challenges, goals, and lessons learned as the team continues its mission to promote telescope modeling for real-world applications. The presentation, Telescope Modeling with SysML, provides an overview of the previous results from SE2, and the current challenges and goals for the next generation Telescope Modeling Challenge Team.
