System Modeling Environment (SME)  Used by system modelers to perform MBSE in the broader context of Model-Based Engineering (MBE)  Provide basic capabilities that include: –model construction –model visualization –model analysis –model management –model exchange and integration –support for MBSE collaboration and workflow  Impose requirements on both the modeling language and the tools 4

System Modeling Environment Basic Functionality in Support of MBSE 5

Effectiveness Measures  Improve systems engineering productivity, quality, and management of complexity and risk –Expressive: Ability to express the system concepts –Precise: Representation is unambiguous and concise –Presentation/communication: Ability to effectively communicate with diverse stakeholders –Model construction: Ability to efficiently and intuitively construct models –Interoperable: Ability to exchange and transform data with other models and structured data –Manageable: Ability to efficiently manage change to models –Usable: Ability for stakeholders to efficiently and intuitively create, maintain, and use the model –Adaptable/Customizable: Ability to extend models to support domain specific concepts and terminology 6

Driving Requirements 7  Driving requirements for the next-generation system modeling language and tools have been identified as highlighted below. 1.Express the core systems engineering concepts. 2.Include precise semantics that avoid ambiguity and enable a concise representation of the concepts. impact assessment of a requirement or design change integrate with equation solvers, execution environments, & capture quantitative data. 3.Provide flexible and rich visualization and reporting capabilities to support a broad range of model users. 4.Enable much more intuitive and efficient model construction. 5.Integrate across discipline-specific engineering tools, including hardware and software design, analysis and simulation, and verification.

8 6.Provide a standard application program interface (API) to provide dynamic access to the model. 7.Capable of being managed in a heterogeneous and distributed modeling environment. 8.Enable efficient and intuitive use by a broad range of users with diverse skills. 9.Must be highly adaptable and customizable to multiple application domains. 10.Support the migration of existing models with minimum information loss. 11.Enable evolution of the above capabilities that take advantage of on-going advances in technologies, concepts, methods, and theories. Driving Requirements (cont.)

 Develop concepts for each driving requirement  Capture in a System Modeling Environment concept white paper  Vet among the community  Derive requirements for SysML v2 RFP 9 Next Steps

ROADMAP APPROACH 10

 For each capability area –Assess the current state to identify capabilities and limitations –Develop the concept and requirements and refine the moe’s that reflects the vision for how this can and should be done in the future –Determine near term, mid term, and long term improvements that can be realized Identify and leverage current activities, research, and initiatives where practical –Develop a follow-up plan on how to move forward  Integrate the concepts from each task area into an overall system modeling environment concept and roadmap that supports MBSE in the context of Virtual Engineering 11 Systems Modeling Environment Roadmap Approach

 Develop MBSE Use Cases  Update System Engineering Concept Model  Assess current state and develop concepts and requirements for each capability area –Model Construction –Model Visualization –Model Analysis –Model Interoperability –Model Management –Workflow Management –Collaboration Management  Evolve system modeling environment –Requirements, concepts, and prototype implementations –Implementation plans for near term, mid term, long term RTF, RFI’s, RFP’s 12 Systems Modeling Environment Roadmap Summary
