  11. 11. Systems Engineering – A (long) definition Systems Engineering is an interdisciplinary approach and means to enable the realization of successful systems. It focuses on defining customer needs and required functionality early in the development cycle, documenting requirements, then proceeding with design synthesis and system validation while considering the complete problem: Source: INCOSE Website – What is Systems Engineering? Operations Cost Schedule Performance Training Support Test Disposal Manufacturing Systems Engineering integrates all the disciplines and specialty groups into a team effort forming a structured development process that proceeds from concept to production to operation. Systems Engineering considers both the business and the technical needs of all customers with the goal of providing a quality product that meets the user needs.
  12. 12. Systems Engineering – Another definition Systems Engineering focuses on ensuring the pieces work together to achieve the objectives of the whole. Source: Systems Engineering Body of Knowledge (SEBoK)

Systems Engineering – explained… Other domains engineering (e.g. optical, biological, medical, …) SEMP Lifecycle Management Requirements (RVTM) Infrastructure Management Software Engineering Project Management HR Management Electrical Engineering Mechanical Engineering CONOPS FMEA Sys tems Engineer ing Portfolio Management Quality Management Risk Management Maintenance ISO/IEC 15288 Configuration Management Disposal
  14. 14. Typical system life cycle Concept • Analyze stakeholder needs and identify concepts Development • Engineer a buildable system that meets stakeholder requirements Production • Build the system Utilization and support • Operate and maintain the system Disposal • Retire, archive, or otherwise dispose the system.
  15. 15. The worries of today’s projects The global market demands ever more complex systems while shorter time-to-market times, high quality, and decreasing costs.

  21. 21. Model-based Systems Engineering Model-based Systems Engineering (MBSE) is the formalized application of modeling to support system requirements, design, analysis, verification and validation activities beginning in the conceptual design phase and continuing throughout development and later life cycle phases.

  24. 24. OMG Systems Modeling Language SysML is designed to provide simple but powerful constructs for modeling a wide range of systems engineering problems. It is particularly effective in specifying requirements, structure, behavior, allocations, and constraints on system properties to support engineering analysis. Source: OMG SysML™ 1.3 specification
  25. 25. Short history of SysML January 2001: INCOSE establishes a working group to adapt the UML for Systems Engineering July 2001: INCOSE OMG jointly chartered the OMG SE DSIG In the following years there have been some disagreements and competing ideas … … but in 2006 a SysML specification proposal was adopted by the OMG. September 2007: SysML 1.0 was officially released by OMG Since June 2012: Version 1.3 Version 1.4 is ready and will be published soon

  27. 27. Delimitation between UML and SysML New diagrams, e.g.: block definition diagram, requirements diagram, … New elements, e.g.: requirement, allocation, support for continuous systems New notations SysML excludes some UML model elements explicitly, e.g. components ++ -- SysML = UML ++ --

  40. 40. INCOSE Vision 2025 Formal systems modeling is standard practice for specifying, analyzing, designing, and verifying systems, and is fully integrated with other engineering models. System models are adapted to the application domain, and include a broad spectrum of models for representing all aspects of systems. Source: INCOSE Vision 2025 (June 2014), page 24

Challenge: System modeling and CAD Functional architectures of systems for mechanical engineers http://fasform.de Joint research and development project with four partners Funded by ZIM (Zentrales Innovationsprogramm Mittelstand) of German Ministry of Economic Affairs Development of methods and tools for the transition of system functions to construction (CAD)
  44. 44. Conclusion Systems Engineering as an interdisciplinary approach to develop complex products will strongly gain in importance The document-based approaches from the industrial age are no longer suitable in the era of ever-increasing complexity MBSE is a key success factor of modern Systems Engineering
