The introduction of Systems Engineering (SE) for the mechatronic product development is important even in classic engineering companies and shall be discussed. Therefore, companies are asking the question, what added value is offered by the integration of SE with respect to their conventional and established development process as well as what benefits will arise with respect to a shortening of the development time, cost savings such as an increase in productivity, quality and innovation. Rightly so, the question must also be asked, how high the investments in Systems Engineering processes, methods and IT-Tools are to be expected for a company. In the following contribution the challenges and benefits of SE will be presented. The deliberate introduction of “Model Based Systems Engineering” (MBSE) can aid in the conversion from a document-centered approach to a model-based development methodology in order to exploit the desired potential benefits. This paper presents the experience of the introduction and adaptation of MBSE based on the example of machine development.

Performing system-level trade studies during the design of complex systems has many benefits in terms of performance, reliability, and cost. However, current engineering practices often do not facilitate system-level trade studies because system specifications and requirements are not connected to analytical models that are used to predict performance and cost. To bridge the gap, authors have created a bridge between system architecture models and engineering analyses. This work extends the bridge between the system modeling language (SysML) and engineering analyses to support the use of parts catalogs from system architecture models. Complex systems such as automobiles are seldom created from scratch. Rather, there are many off-the-shelf parts and subsystems available. Combined with the bridge between SysML and engineering analyses, parts catalog data available from system models enables evaluating many different configurations of a system and identifying best designs. The technical approach is demonstrated using an automobile brake design example. The integrated approach allowed generating a large number of design configurations and evaluating those using engineering analyses. Multidimensional point cloud visualization techniques were applied to identify trade-offs between cost and system performance. It is discussed how the interactive point cloud visualization technique can be used to perform requirements change impact analysis

This paper documents the development of a conceptual level integrated process for design and analysis of efficient and environmentally acceptable supersonic aircraft. To overcome the technical challenges to achieve this goal, a conceptual design capability which provides users with the ability to examine the integrated solution between all disciplines and facilitates the application of multidiscipline design, analysis, and optimization on a scale greater than previously achieved, is needed. The described capability is both an interactive design environment as well as a high powered optimization system with a unique blend of low, mixed and high-fidelity engineering tools combined together in the software integration framework, ModelCenter. The various modules are described and capabilities of the system are demonstrated. The current limitations and proposed future enhancements are also discussed.

In the frame of the ESA e.Deorbit study (Architecture Definition phase), a highly integrated and collaborative MBSE process related to Systems Modelling and Simulation has been developed and applied for supporting the iterative generation and maturation of the system requirements, architectures and system budgets at phase B1 level. e.Deorbit is a compelling mission concept that addresses the most pressing debris challenge for Europe: the post-life disposal of ESA’s environmental satellite Envisat. The e.Deorbit robotic-based chaser is characterized by strong safety (avoid collisions between chaser and target) and autonomy (capabilities to operate automatically with ground supervision) features. Additionally, the system complexity w.r.t.
