Such tools call a Computer Algebra System (CAS) to solve simultaneous equations defined in parametric diagrams. But now, several commercial SysML tools support analysis using parametric diagrams. Until several years ago, no SysML modeling tool supports analysis using parametric diagrams, so very few SysML users draw parametric diagrams. If these constraints are well defined, an analysis tool can be developed to perform various kinds of analysis such as determining whether the values of the various systems attributes satisfy constrains. Parametric diagrams are used to specify constraints and associate them with the design elements as an integral part of the overall engineering model.

SysML also supports engineering analysis using parametric diagrams. Some researchers integrate SysML with Simulink, and others integrate SysML with Modelica. Various researchers proposed integration of a SysML tool with a simulation tool to perform both systems engineering process and simulation. To develop a complex system, we have to perform systems engineering processes before defining detailed behavior.

Although a simulation tool is well suited for defining a detailed behavior of dynamic system, it is not well suited for conducting the overall systems engineering processes such as requirement analysis and architectural analysis. To simulate a combination of discrete-time and continuous-time elements, we have to use a simulation tool such as Simulink or Modelica. To simulate a system that consists of hardware and software, we have to define both discrete-time behavior and continuous-time behavior. One of the most effective methods of verifying a system is simulation. Using differential equations allows one to fully specify dynamic behavior however, they are inadequate to design the reactive and transformational behaviors of the designed system parts. It is possible to define dynamic behavior of the system using time derivative function. In addition, SysML introduces a new kind of diagram called a parametric diagram used to define mathematical relations among attributes of the system using equations and inequalities. Part of the control systems specification includes dynamic (time-dependent) continuous behavior of the control algorithms and the physical environment these systems interact with the plant.

SysML extends a subset of the Unified Modeling Language (UML) targeted mainly for software engineering. The need for a standard modeling language originates from the fact that interdisciplinary complex systems, which require high-quality efficient systems engineering activities, are being developed by different teams, sometimes across companies in different countries, using a variety of tools and methods. The Systems Modeling Language (SysML) has been under development since 2001 by the International Council of Systems Engineering (INCOSE) and the Object Management Group (OMG) organizations, as a standard modeling language for model-based systems engineering (MBSE). The authors also show the overall approach using a Dual Clutch Transmission (DCT) and a Cruise Control System as examples. The integration with a CAS enables the evaluation of mathematical constraints defined in SysML parametric diagrams. The integration with Simulink enables users to perform systems engineering process in a SysML model, while designing continuous control algorithms and plant behavior in Simulink, and to validate the behavior by simulating the overall composition in Simulink. The authors demonstrate how they can integrate a SysML modeling tool (IBM Rational Rhapsody) with a proprietary simulation tool (MathWorks Simulink) and a Computer Algebra System (CAS) to validate system specification. SysML supports the specification, analysis, and design of a broad range of complex systems such as control systems.
