Real-time system modeling with ACCORD/UML methodology: Illustration through an automotive case study.
Trung Hiếu Phan, Sébastien Gérard, François Terrier · Kluwer Academic Publishers eBooks · 2003
Engineers are now facing difficult problems in developing ever more sophisticated real-time systems with reduced time-to-market constraints. Object-oriented modeling with UML provides useful answers to these challenges. However, UML specification of real-time features and implementation techniques for real-time applications still require improvement. The ACCORD/UML methodology outlined in this paper therefore proposes UML extensions for modeling real-time complex systems with a high level of abstraction, followed by a basic technology for prototyping and a set of validation methods. ACCORD/UML is fully in line with the MDA paradigms proposed by the OMG. It focuses on system real-time constraints specification and ensures automatic developing phases to guarantee safe construction and application correctness. Throughout this paper, an automotive case study, based on a car seat adjustment system, is used to illustrate the ins and outs of ACCORD/UML methodology.
