Using UML for modeling complex real-time systems

James Rumbaugh, Staff, IBM
James Rumbaugh
Jim Rumbaugh currently leads IBM Rational's modeling efforts in relation to databases and transformations, and is also supporting the transition to UML 2.0 for its users, including IBM's own software engineering teams.

He was named Distinguished Engineer for his long-time thought leadership in the field of object-oriented modeling, which embraces both standardization of the technology within the Object Management Group (OMG) and the practical application of those standards. One of the "founding fathers" and chief luminaries of object-oriented modeling, he has authored or co-authored five best-selling books on the subject. He also holds four patents, and his contributions have been central to IBM Rational's market leadership in modeling tools.

Jim Rumbaugh received his PhD in Computer Science from the Massachusetts Institute of Technology (MIT) in 1975.
Branislav SelicIBM
Bran Selic currently leads IBM's collaborative efforts with the Object Modeling Group (OMG) and heads the task force that is finalizing the UML 2.0 standard. He also works on an internal development team to optimize the implementation of UML 2.0 in IBM Rational's next generation of model-driven software development tools.

Named Distinguished Engineer for his pioneering work with model-driven software development techniques as well as his pivotal contributions to the UML modeling standard, he has supported the incorporation of those techniques and standards into commercial development tools and industry practice. He co-authored one of the first published works describing model-driven development, and his ideas about model-driven architecture (MDA) are at the foundation of modern software engineering best practices. In addition to editing two more books, authoring chapters in five books, and publishing numerous papers, he has held a wide range of academic positions. Currently, he serves on several industry editorial and advisory boards and technical committees concerned with model-driven development.

Bran Selic completed his Magister Ing (MS equivalent) in Systems Theory at the University of Belgrade in 1974.

Summary:  This paper describes a set of constructs that facilitate the design of software architectures for embedded development, with an emphasis on how the extensibility mechanisms of UML can be applied to work in this domain.

We apply the Unified Modeling Language (UML [2], [3]) to describe a set of constructs suitable for modeling an important category of real-time software systems. They are derived from the set of concepts initially defined in the ROOM modeling language.
