SysML Package Diagram

The parametric diagram is a new SysML diagram type that describes the constraints among the properties associated with blocks. This diagram is used to integrate behavior and structure models with engineering analysis models such as performance, ...

MagicDraw/Cameo support for the SysML Parametric Diagram and ConstraintBlocks for equations and mathematics is excellent, and it integrates with powerful maths engines such as Mathematica. It CAN be used on industrial strength real-world projects.

The SysML Parametric Diagram and the ContraintBlock technology for equations and mathematics is clever, powerful, useful, and integrates well with the other model-based engineering aspects of SysML.

MagicDraw/Cameo can parse the 'text' field of some mathematical Requirements and populate the constraint (and also then the constraint parameters) of a ConstraintBlock that refines a Requirement (your mileage varies).

The constraints and parameters in Figure D.33 are detailed in Figure D.34 in Block Definition Diagram format. Note the use of valueTypes [ValueTypes] originally defined in Figure D.2.

Figure D.26 defines the various model elements that will be used to conduct analysis in this example. It depicts each of the constraint blocks/equations that will be used for the analysis, and key relationships between them.

The context for the usages of constraint blocks shall also be specified in a parametric diagram to maintain the proper namespace for the nested properties.

This allows a value property (such as an engine displacement) that may be deeply nested within a containing hierarchy (such as vehicle, power system, engine) to be referenced at the outer containing level (such as vehicle-level equations).

A pathname dot notation can be used to refer to nested properties within a block hierarchy.

The constrained properties, such as mass or response time, typically have simple value types that may also carry units, quantity kinds, or probability distributions.

OMG Systems Modeling Language (SysML) 1.6

The usage of a constraint binds the parameters of the constraint, such as F, m, and a, to specific properties of a block, such as a mass, that provide values for the parameters.

Source

OMG Systems Modeling Language (SysML) 1.6

Parametric diagrams include usages of constraint blocks to constrain the properties of another block.

Source

OMG Systems Modeling Language (SysML) 1.6

The constraints can be nested to enable a constraint to be defined in terms of more basic constraints such as primitive mathematical operators.

OMG Systems Modeling Language (SysML) 1.6

Reusable constraint definitions may be specified on block definition diagrams and packaged into general-purpose or domain-specific model libraries. Such constraints can be arbitrarily complex mathematical or logical expressions.

Source

OMG Systems Modeling Language (SysML) 1.6

Constraint blocks define generic forms of constraints that can be used in multiple contexts. For example, a definition for Newton’s Laws may be used to specify these constraints in many different contexts.

Source

OMG Systems Modeling Language (SysML) 1.6

A constraint block includes the constraint, such as {F=m*a}, and the parameters of the constraint such as F, m, and a.

Source

OMG Systems Modeling Language (SysML) 1.6

Such constraints can also be used to identify critical performance parameters and their relationships to other parameters, which can be tracked throughout the system life cycle.

Source

OMG Systems Modeling Language (SysML) 1.6

Constraint blocks can be used to specify a network of constraints that represent mathematical expressions such as {F=m*a} and {a=dv/dt}, which constrain the physical properties of a system.
