Abstract

Real-time and embedded systems have widespread use in industrial, commercial and defence applications. They tend to be large and complex and need to focus on non-functional aspects such as performance, throughput and dependability. The UML has demonstrated potential for modeling real-time and embedded systems, but this potential can be greatly enhanced with the use of DORIS, a method extensively used in the aerospace industry. This paper considers how the two can be used in combination to model complex systems.
