System Design Using SysML

Overview
The course provides an introduction to the concepts and philosophy underlying Systems Engineering (SE), the use of SysML as a notation, and how SysML relates to UML.
The ethos is very much that of providing a common ground and notation that allows hardware engineers and software engineers to communicate with one another so that their analysis and design efforts can be more fully integrated.
This course is a hands on course and will include use of a SysML modeling tool [ currently the choice is between Enterprise Architect and Artisan Studio. However, do inquire is you would like a course tailored to some other tool ]
The main objectives of the course are

• to develop the skills and understanding needed to apply system engineering techniques to a project
• to provide a comprehensive coverage of system engineering concepts and methods
• to provide an in depth account SysML notation
• to illustrate how SysML and UML2 relate to one another and how they can be used to facilitate communication between hardware and software engineers

Key skills learned

• requirements analysis and design techniques
• a working paradigm for defining system architectures
• approaches to modelling the dynamic behaviour of a system
• techniques for assessing and analysing system performance
• SysML notation and how to use it effectively
