This section provides an overview of the Systems Modeling Language (SysML), the industry standard architecture modeling language for specifying large, complex systems. The overview includes a formal definition and information about SysML core concepts, origins, characteristics, enabling technologies, and variations.
The SysML was originally created by the SysML Partners' SysML Open Source Specification Project in 2003. The SysML was adapted and adopted by the Object Management Group (OMG) as OMG SysML in 2006. For more information about the current version of OMG SysML, see the SysML FAQ: What is the current version of SysML?.
The SysML Forum is a web community dedicated to the Systems Modeling Language (SysML), an open standard architecture modeling language for systems engineering applications. Since SysML is a popular dialect (technically a Profile) of UML v. 2, the industry standard for specifying software-intensive architectures, it is a popular choice as a lingua franca for Model-Based Systems Engineering ...
What is a SysML Internal Block Diagram? Definitions Block: A Block (notation: rectangle with keyword = «block») represents a system component, a modular structural unit that encapsulates its contents (Properties, Behaviors, Constraints) and supports first-class (i.e., can be drawn and directly manipulated in the model repository) Interfaces.
Cameo Systems Modeler (Cameo) is a robust Model-Based Systems Engineering (MBSE) tool that strictly enforces most of OMG SysML's syntax and semantics, and offers support for basic requirements traceability, intermediate model-based simulation, and automated document generation.
SysML offers systems engineers the following advantages over UML for specifying systems and systems-of-systems: • SysML expresses systems engineering semantics (interpretations of notations) better than UML.
SysML is an enabling technology for Model-Based Systems Engineering (MBSE). The SysML was originally created by the SysML Partners' SysML Open Source Specification Project in 2003. The SysML was adapted and adopted by the Object Management Group (OMG) as OMG SysML in 2006.
A SysML Block is a modular unit of system structure (i.e., a component) that encapsulates its contents (Properties, Behaviors, Constraints) via provided and required Interfaces, and classifies (types) runtime objects (i.e., Block Instances) that are instantiated from the subject Block. SysML Blocks are analogous to UML 2 Structured Classes and UML 2 Components. See SysML FAQ: What is the ...
What is the difference between a Block Definition Diagram (BDD) and an Internal Block Diagram (IBD)? Block Definition Diagrams (BDDs) and Internal Block Diagrams (IBDs) work in a complementary manner to recursively generate structures of arbitrary complexity during System Analysis & Design. This is necessary because the System-of-System Engineering problem is fractal in nature, where systems ...
What is a SysML Requirement diagram? Definitions Requirement: A Requirement (notation: rectangle with «requirement» keyword) is a capability or condition that a system must ("shall") satisfy. A Functional Requirement («functionalRequirement» keyword) specifies a function that a system must perform, whereas a Non-Functional Requirement (NFR) specifies quality criteria that can be used to ...
