Back to SysML v2 RFP Working Group
The Systems Analysis Workgroup is formed under the SysML Assessment and Roadmap Working Group to research and gather requirements for seamless and integrated analyses of complex systems across their lifecycle. This workgroup focuses on the system analysis challenge stated in INCOSE Insight article (Vol 18, Issue 2, Aug 2015) Evolving SysML and the System Modeling Environment to Support MBSE that states:
The next-generation modeling language must include precise semantics that avoid ambiguity and enable a concise representation of the concepts. SysML currently leverages the UML metamodel for much of its semantic foundations. The language must derive from a well-specifed logical formalism that can leverage the model for a broad range of analysis and model checking. This includes the ability to validate that the model is logically consistent, and the ability to answer questions such as the impact of a requirement or design change, or assess how a failure could propagate through a system. The language and tools must also integrate with a diverse range of equation solvers and execution environments that enable the capture of quantitative data.
The System Analysis Workgroup is pursuing the following goals for SysML 2.0:
System Analysis is the systematic investigation of a real or planned system to (a) compare and select candidate system architectures, or (b) determine causes & resolutions of failures / exceptions [SEBoK - http://goo.gl/RCtAKt, NASA SE Handbook (2007) - http://goo.gl/iVBVES]. Some common examples of system analysis are as follows:
The current generation of SysML (1.x) has the following challenges related to formulating, representing, and executing system analyses.
