==SysML Introduction⌘==<br />
=== Copyright ⌘===<br />
Most of our training material is based on the OMG's SysML Specification http://www.omg.org/spec/SysML<br />
===SysML⌘===<br />
[[File:OMG_SysML_logo.gif]]<br />
* Systems Modeling Language<br />
* OMG specification, current version: 1.5, release date: May 2017<br />
* http://www.omg.org/spec/SysML/Current<br />
* SysML is a general-purpose graphical modeling language for specifying, analyzing, designing, and verifying complex systems that may include hardware, software, information, personnel, procedures, and facilities.<br />
* SysML provides semantics (meaning) and notation (representation of meaning).<br />
* SysML is methodology and tool independent<br />
<br />
===Systems Engineering⌘===<br />
[[File:SIMILAR_process.png]]<br />
* '''Systems Engineering''' is an engineering discipline whose responsibility is creating and executing an interdisciplinary process to ensure that the customer and stakeholder's '''needs are satisfied''' in a high quality, trustworthy, cost efficient and schedule compliant manner throughout a system's entire life cycle. <br />
* This process is usually comprised of the following seven tasks: '''S'''tate the problem, '''I'''nvestigate alternatives, '''M'''odel the system, '''I'''ntegrate, '''L'''aunch the system, '''A'''ssess performance, and '''R'''e-evaluate. <br />

===DBSE vs. MBSE⌘===<br />

* Document-based systems engineering approach uses textual documents that are exchanged between stakeholders<br />
* Model-based systems engineering uses systems modeling as a part of the SIMILAR process.<br />
* System model includes system specification, analysis, design, ... and is stored in a repository.<br />
===The four pillars of system modelling⌘===<br />

===SysML/UML Interrelationship⌘===<br />
[[File:SysML_and_UML.png]]<br />
<br />
SysML reuses a subset of UML 2 and provides additional extensions needed to address requirements of Systems Engineering.<br />
<br />
===SysML diagrams⌘===<br />
[[File:SysML_diagrams.png]]<br />
<!--<br />
A block definition diagram is based on the UML class diagram, with restrictions and extensions as defined by SysML.<br />
An internal block diagram is based on the UML composite structure diagram, with restrictions and extensions as defined by SysML.<br />
A parametric diagram is a restricted form of internal block diagram that shows only the use of constraint blocks along with the properties they constrain within a context.<br />
--><br />
<br />
===SysML diagram frame⌘===<br />
[[File:SysML_DiagramFrame.png]]<br />
<br />
<source lang=bnf><br />
<headingName> ::== <br />
<diagramKind> ['['modelElementType']'] <modelElementName> ['['diagramName']']<br />
</source><br />
<br />
The frame is a rectangle that is required for SysML diagrams (Note: the frame is optional in UML).<br />
====Diagram Kind⌘====<br />
* SysML diagram kinds should have the following names or (abbreviations) as part of the heading:<br />
** activity diagram ('''act''')<br />
** block definition diagram ('''bdd''')<br />
** internal block diagram ('''ibd''')<br />
** package diagram ('''pkg''')<br />
** parametric diagram ('''par''')<br />
** requirement diagram ('''req''')<br />
** sequence diagram ('''sd''')<br />
** state machine diagram ('''stm''')<br />
** use case diagram ('''uc''')<br />
