systems engineering

Many years ago, on a very old version of the Webel site, I had up a quick attempt at mapping out the families of physics particles in SysML. Although I have a PhD in physics (astrophysics), and had even worked at the DESY particle accelerator institute (on data analysis, and modelling and operating the machines, not particle physics), I am not an expert in particle physics.

Dr Darren says:

Welcome, if you have been referred here it may be in response to my sending a link to this page in reply to your comments or questions on LinkedIn.

To all LinkedIn groups involving MBSE, Systems Engineering, SysML, and the MagicDraw/Cameo tools,

I am no longer offering comments or answering questions in comment threads (or in reply to LinkedIn messages) on any LinkedIn group involving MBSE, SysML, or SysML tools.

SysML: Naming: You may include Block, ValueType, and Signal names in the names of Behaviors (such as Activities) as long as this does not undermine the principles of functional analysis and allocation.

SysML: Naming: Including Block, ValueType, and Signal names in the names of Behaviors (such as Activities) can sometimes undermine purist functional allocation (because it may presuppose the element of the physical solution that carries out the function).

MagicDraw SysML/Cameo: If you have a SINGLE Allocate from an Activity to a Block it will set that Block to be the Behavior::/context for that Activity.

SysML: Having a Behavior owned by a Block it is allocated to may undermine purist functional allocation (because it presupposes the element of the physical solution that carries out the function)

UML Class Diagram

SysML blocks can be used throughout all phases of system specification and design, and can be applied to many different kinds of systems.

Source

OMG Systems Modeling Language (SysML) 1.6

SysML Blocks also extend the capabilities of UML classes and connectors with reusable forms of constraints, multi-level nesting of connector ends, participant properties for composite association classes, and connector properties.

Source

OMG Systems Modeling Language (SysML) 1.6

SysML blocks always include an ability to define internal connectors, regardless of whether this capability is needed for a particular block.

Source

OMG Systems Modeling Language (SysML) 1.6

SysML blocks are based on UML classes as extended by UML composite structures. Some capabilities available for UML classes, such as more specialized forms of associations, have been excluded from SysML blocks to simplify the language.

Source

OMG Systems Modeling Language (SysML) 1.6

Blocks may also specify operations or other features that describe the behavior of a system

Source

OMG Systems Modeling Language (SysML) 1.6

SysML also allows each usage to define context-specific values and constraints associated with the individual usage, such as 25 psi for the front tires and 30 psi for the rear tires.

Source

OMG Systems Modeling Language (SysML) 1.6

For example, a block that represents the definition of a wheel can be used in different ways. The front wheel and rear wheel can represent different usages of the same wheel definition.

Source

OMG Systems Modeling Language (SysML) 1.6

A part belonging to a block, for example, may be typed by another block. The part defines a local usage of its defining block within the specific context to which the part belongs.

Source

OMG Systems Modeling Language (SysML) 1.6

A property can represent a role or usage in the context of its enclosing block. A property has a type that supplies its definition.

Source

OMG Systems Modeling Language (SysML) 1.6

Various notations for properties are available to distinguish these specialized kinds of properties on an internal block diagram.

Source

OMG Systems Modeling Language (SysML) 1.6

Constraint Properties are a special class of property used to constrain other properties of blocks...

Source

OMG Systems Modeling Language (SysML) 1.6

Ports are a special class of property used to specify allowable types of interactions between blocks ...

Source

OMG Systems Modeling Language (SysML) 1.6

A block can include properties to specify its values, parts, and references to other blocks.

Source

OMG Systems Modeling Language (SysML) 1.6

The Internal Block Diagram in SysML captures the internal structure of a block in terms of properties and connectors between properties.

Source

OMG Systems Modeling Language (SysML) 1.6

It captures the definition of blocks in terms of properties and operations, and relationships such as a system hierarchy or a system classification tree

Source

OMG Systems Modeling Language (SysML) 1.6

The Block Definition Diagram in SysML defines features of blocks and relationships between blocks such as associations, generalizations, and dependencies.

Source

OMG Systems Modeling Language (SysML) 1.6

Parts in these systems may interact by many different means, such as software operations, discrete state transitions, flows of inputs and outputs, or continuous interactions.

Source

OMG Systems Modeling Language (SysML) 1.6

These include modeling either the logical or physical decomposition of a system, and the specification of software, hardware, or human elements.

Source

OMG Systems Modeling Language (SysML) 1.6

The specific kinds of components, the kinds of connections between them, and the way these elements combine to define the total system can all be selected according to the goals of a particular system model.

Source

OMG Systems Modeling Language (SysML) 1.6

Blocks provide a general-purpose capability to model systems as trees of modular components.

Source

OMG Systems Modeling Language (SysML) 1.6

Each block defines a collection of features to describe a system or other element of interest. These may include both structural and behavioral features, such as properties and operations, to represent the state of the system and behavior ...

Source

OMG Systems Modeling Language (SysML) 1.6

Blocks are modular units of system description.

Source

OMG Systems Modeling Language (SysML) 1.6

Even relatively informal elicitation of model elements using the SysML ElementGroup and a Parsing Analysis approach is extremely powerful.

Translating authoritative technical documents written in “natural” engineering language (snippet-by-snippet) into Webel Parsing Analysis diagrams creates consistent underlying systems models and can bridge easily to existing methodologies.

The OMG SysML language deliberately does not aim to restrict users and tools to one strict systems engineering methodology; it provides flexible capabilities and options for use by many model-based systems engineering methodologies and tools.

The SysML Copy relationship can be used to "import" Requirements from an existing read-only library into a new project context.

Systems engineers have frequent need to allocate structural model elements (e.g., blocks, parts, or connectors) to other structural elements.

Audience: Users of MagicDraw SysML or Cameo Systems Modeler who are experimenting with creating custom stereotypes that extend Block.

This screencast video has been created to demonstrate some issues that can arise if you "naively" create a custom stereotype that extends Block without: (1) closing then re-opening your project; (2) creating an appropriate MD Customization. It is not about any actual "bug" in MagicDraw/Cameo (as long as you follow the recommended procedure). If you watch it, please do watch it to the end to find how to handle such stereotypes properly.

Audience: Users of MagicDraw SysML or Cameo Systems Modeler who are experimenting with creating custom stereotypes for SysML.

This screencast video has been created to illustrate some pros and cons of using custom stereotypes in combination with Block inheritance and Part Property structures, and demonstrates some possible "gotchas". It concerns especially use of custom stereotypes to indicate: (1) cross-cutting aspects such as model layer membership; (2) use of tagged values to carry per-Element metadata.
