The Systems Modeling Language (OMG SysML) is a general purpose modeling language that allows users to express a broad range of information and knowledge about systems and systems engineering projects: from requirements to functional architectures, and from behavior to structural specifications. An important set of modeling constructs in SysML are parametric constraints as used in parametric diagrams. SysML parametrics allow systems engineers not only to define parametric system specifications but also to express analysis models relating mmeeaasusurrees s ooff eeffffeectctiivevenneess ss ttoo sysyststeemm spspeeciciffiicacattiioonns.s. IInn tthhiis s ttuuttoorriiaall,, tthhee uusese ooff paramtrics for analysis purposes will be reviewed in detail. To provide the appropriate context, we will start with a short overview of SysML, followed by a more detailed review of the syntax and semantics of parametric diagrams. We will then discuss different uses of parametrics, and provide best-practice examples, specifically focusing on analysis modeling. Parametric diagrams will also be compared with a new OMG specification for combining SysML and Modelica: The OMG SysML-Modelica Transformation Specification. A live demonstration will be included with the following two tools: The MagicDraw SysML Tool with the ParaMagic plug-in, and an open-source plug-in for solving parametric constraint models in ModelCenter.
