6.6.2 Determining the right solution using SysML and model based systems engineering (MBSE) for trade studies

With the recent widespread adoption of the Object Management Group (OMG) Systems Modeling Language (SysML) by the systems engineering community to properly capture system requirements, functional and architectural design, and detailed interfaces and design characteristics, it is a natural next step to apply SysML with proven trade study techniques to leverage a robust approach through which to explore the design space and ensure coverage of nonfunctional and performance requirements. This paper not only shows this robust technique with Model Driven Systems Engineering (MBSE) and SysML, but it also provides a methodology that enables users to properly explore the design space with execution analysis—all from within the design model, something that was often missing from previous techniques around trade study analysis. Having access to the proposed design solutions and being able to perform trade‐off analysis from within an engineering model has numerous benefits, which this paper discusses.
