SysML

This example was drawn on the base of SysML activity diagram on the page 8 of "SysML Modelling Language explained" document from the Official OMG SysML site.
"The activity diagram represents steps of a process, often making use of “input and output pins” that respectively correspond to the element type required as the input of an activity or action, and the element generated as an output.
If an action or activity corresponds to a block operation, it is possible to ensure that the types of the input and output of this activity are consistent with the block operation signature.
All the activity diagrams definitions used in UML also apply to SysML.
SysML has added a couple of extensions:
- With UML, control can only enable actions to start. SysML extends control to support disabling of actions that are already executing.
- Definition of the flow rate : continuous or discrete
- Definition of the rate and probability on the control or object flows"

The example "SysML activity diagram" was drawn using the ConceptDraw PRO diagramming and vector drawing software extended with the SysML solution from the Software Development area of ConceptDraw Solution Park.

This example was drawn on the base of figure 1 on the webpage "Template: OASIS:FunctionalBreakdownStructure" from the OASIS website.
"The FunctionalBreakdownStructure template describes how to represent a relationship between a FunctionalElementDefinition and another FunctionalElementDefinition that is a constituent.
The SysML Block Definition diagram in Figure 1 shows how a functional breakdown is represented in the PLCS PSM."

This SysML diagram example was redesigned from Wikimedia Commons file: Use case restaurant model.svg.

"The use case diagram describes the usage of a system (subject) by its actors (environment) to achieve a goal, that is
realized by the subject providing a set of services to selected actors. The use case can also be viewed as functionality and/
or capabilities that are accomplished through the interaction between the subject and its actors. Use case diagrams include the use case and actors and the associated communications between them. Actors represent classifier roles that are external to the system that may correspond to users, systems, and or other environmental entities. They may interact either directly or indirectly with the system. The actors are often specialized to represent a taxonomy of user types or external systems." [omg.org/ spec/ SysML/ 1.3/ ]

The vector stencils library "Ports and Flows" contains 26 SysML symbols.
Use it to design your SysML diagrams using ConceptDraw PRO diagramming and vector drawing software.
"The main motivation for specifying ports and flows is to enable design of modular, reusable blocks with clearly defined
ways of connecting and interacting with their context of use. This clause extends UML ports to support nested ports, and
extends blocks to support flow properties, and required and provided features, including blocks that type ports. Ports can be typed by blocks that support operations, receptions, and properties as in UML. SysML defines a specialized form of Block (InterfaceBlock) that can be used to support nested ports. SysML identifies two kinds of ports, one that exposes
features of the owning block or its internal parts (proxy ports), and another that supports its own features (full ports). Default compatibility rules are defined for connecting blocks used in composite structure, including parts and ports, with association blocks available to define more specific ways of doing this. These additional capabilities in SysML enable modelers to specify a wide variety of interconnectable components, which can be implemented through many engineering and social techniques, such as software, electrical or mechanical components, and human organizations. This clause also extends UML information flows for specifying item flows across connectors and associations." [www.omg.org/ spec/ SysML/ 1.3/ PDF]

The vector stencils library "Sequence diagram" contains 32 SysML symbols.
Use it to design your sequence diagrams using ConceptDraw PRO diagramming and vector drawing software.
"A sequence diagram shows, as parallel vertical lines (lifelines), different processes or objects that live simultaneously, and, as horizontal arrows, the messages exchanged between them, in the order in which they occur. This allows the specification of simple runtime scenarios in a graphical manner. ...
If the lifeline is that of an object, it demonstrates a role. Leaving the instance name blank can represent anonymous and unnamed instances.
Messages, written with horizontal arrows with the message name written above them, display interaction. Solid arrow heads represent synchronous calls, open arrow heads represent asynchronous messages, and dashed lines represent reply messages. If a caller sends a synchronous message, it must wait until the message is done, such as invoking a subroutine. If a caller sends an asynchronous message, it can continue processing and doesn’t have to wait for a response. Asynchronous calls are present in multithreaded applications and in message-oriented middleware. Activation boxes, or method-call boxes, are opaque rectangles drawn on top of lifelines to represent that processes are being performed in response to the message (ExecutionSpecifications in UML).
Objects calling methods on themselves use messages and add new activation boxes on top of any others to indicate a further level of processing.
When an object is destroyed (removed from memory), an X is drawn on top of the lifeline, and the dashed line ceases to be drawn below it (this is not the case in the first example though). It should be the result of a message, either from the object itself, or another.
A message sent from outside the diagram can be represented by a message originating from a filled-in circle (found message in UML) or from a border of the sequence diagram (gate in UML)." [Sequence diagram. Wikipedia]

"The Systems Modeling Language (SysML) is a general-purpose modeling language for systems engineering applications. It supports the specification, analysis, design, verification and validation of a broad range of systems and systems-of-systems.
SysML was originally developed by an open source specification project, and includes an open source license for distribution and use. SysML is defined as an extension of a subset of the Unified Modeling Language (UML) using UML's profile mechanism." [Systems Modeling Language. Wikipedia]
