Topic: The Systems Modeling Language (SysML) was originally designed to treat system requirements in a very simplistic way, capturing only the requirement’s name, unique ID, and text string.  While this is very compatible with most requirements management tools, it is not very satisfactory in dealing with complex requirements that refer to physical relationships and properties.  In particular, the growing sophistication of parametric modeling and analysis using SysML has highlighted the need to express numerical requirements more  explicitly. The SysML Revision Task Force (RTF) has been exploring more robust ways of representing requirements, including incorporation of typed values and equations.  While this seems simple on the surface, the implications of these new requirement attributes can be significant and potentially ambiguous.  This presentation will provide an overview of the preferred approaches to incorporating property based requirements in SysML models, and will touch on some of the advantages and pitfalls of adding this capability into the SysML language.
