SysML Intro

SysML Introduction⌘

Most of our training material is based on the OMG's SysML Specification http://www.omg.org/spec/SysML

Systems Modeling Language
OMG specification, current version: 1.5, release date: May 2017
http://www.omg.org/spec/SysML/Current
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.
SysML provides semantics (meaning) and notation (representation of meaning).
SysML is methodology and tool independent

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.
This process is usually comprised of the following seven tasks: State the problem, Investigate alternatives, Model the system, Integrate, Launch the system, Assess performance, and Re-evaluate.

Document-based systems engineering approach uses textual documents that are exchanged between stakeholders
Model-based systems engineering uses systems modeling as a part of the SIMILAR process.
System model includes system specification, analysis, design, ... and is stored in a repository.

SysML reuses a subset of UML 2 and provides additional extensions needed to address requirements of Systems Engineering.
