Abstract
Engineers are increasingly facing the hard problem of
developing more sophisticated real-time systems while time-to-market and cost
constraints are getting more stringent. The adoption of object-oriented modelling in the real-time domain appears to be essential
to cope with the rapidly changing market conditions. The main obstacles to adoption have been the lack of
standards and the mismatch between object-oriented technologies and real-time
needs. Consequently, the OMG has sponsored work on evolving UML standards to
better address real-time issues. In
particular, the OMG has adopted a specific profile that is well suited for
real-time, the UML profile for Scheduling, Performance and Time (SPT). This profile defines a basic set of concepts needed for modelling real-time aspects of an application. By using
these concepts modellers can enhance their
application models with enough information to either produce implementations
or frameworks from annotated UML models, or to analyse
the real-time behaviour of an application for schedulability and various performance characteristics.
SPT provides a framework for the integration of real-time analysis techniques
with UML. This alleviates two problems: § The cognitive gap that exists between software
development and analysis techniques. § The time and effort required for the
construction and maintenance of separate analysis models. In 2003, numerous projects and academic papers
investigated SPT, giving different reasons for either using it or not,
especially in the context of the Artist project (http://www.artist-embedded.org). In parallel, the RTAD (Real-Time Analysis and Design)
working group of the OMG, which commissioned the initial version of the
profile, decided to issue a further Request For Proposal (RfP)
to produce an updated version. This was motivated primarily by the need to
integrate with the newly-adopted major revision of UML (UML 2.0) and the soon
to be adopted UML profile for Quality-of-Service and Fault Tolerance. Therefore, the RTAD is taking the opportunity offered by
the new RfP process, to collect the experiences of
people who have experimented with the SPT profile and on that basis, provide
feedback on its usage. In summary, in addition to offering a forum for
exchanging experiences of using SPT, the goal of this workshop is to gather a
list of requirements and suggested improvements to the existing UML profile
for SPT to be used in drafting the new RfP. Workshop community, series of
workshops
This workshop would be the seventh in a series of
workshops hosted by various conferences: SIVOOES 2000 and Selection process
To participate to this workshop, send a position paper
via email to Sébastien Gérard (Sebastien.Gerard@cea.fr). Submissions should not exceed 4 pages (10 pt., single
space) and should be in one of the following formats: plain text, postscript,
pdf or word. Submissions will be evaluated based on their relevance to
the workshop theme, originality, and on ability to reveal issues that may
animate discussions during the workshop. The accepted papers will be placed
on the workshop web site before the date of the workshop. |
