Until the end of this lab, you must establishyour teams & themes.

Choose one spokesperson (your team leader)and present:◦ Your idea for the project

◦ Timeline for implementation

The Systems Modeling Language is a visual,general purpose modeling language

The basic architectural unit in SysML is theblock.

It is defined as an extension of a subset ofthe Unified Modeling Language (UML)

Improvements:◦ SysML's semantics are more flexible and expressive

◦ Reduces UML's software-centric restrictions

◦ Adds two new diagram types, requirement andparametric diagrams

◦ SysML is able to model a wide range of systems,which may include hardware, software, information,processes, personnel, and facilities

◦ Little language that is easier to learn and apply

SysML reuses seven of UML 2's fourteendiagrams and adds two diagrams

Automotive system. ◦ Requirement diagrams to efficiently capture functional,

performance, and interface requirements ◦ Parametric diagrams to precisely define performance

and quantitative constraints like maximum acceleration, minimum curb weight, and total air conditioning capacity.

◦ Activity diagrams and state machine diagrams can be used to specify the embedded software control logic and information flows for the on-board automotive computers.

◦ Other SysML structural and behavioral diagrams can be used to model factories that build the automobiles, as well as the interfaces between the organizations that work in the factories.

The problem: Goals are too broad – it isdifficult to derive specific systemcharacteristics from goals, and this is whererequirements come in.

Requirements concretize goals by describingin detail what features and characteristics asystem must offer in order to satisfy thestakeholders.

They make requirements comprehensible.

They provide an easy overview of your system.

They ensure traceability of product development.
