First year report to ARTES : Automatic Control in Distributed
Applications (AIDA 2). 9811-2
1) A comparison between project plan and results including updates or
changes in research direction. Any issue that you feel is important for
ARTES to know.
The project has had a good start. Jad Elkhory is a promising PhD student.
During the first year, an initial state of the art study has been carried
out [2], an industrial reference group has been formed, and theoretical
and practical studies are well under way.
The expected results of the project, according to the project application
are
- a further developed modelling framework
- a prototype tool-set,
- a method providing design guidelines and on how to utilize the develop
models and the toolset.
During the year, Jad Elkhoury has spent an effort on developing a prototype
extension to Simulink from the Mathworks, the background and motivation
is elaborated in [2]. The basic idea is to be able to carry out architectural
design based on an industrially very commonly used tool. The work has entailed
providing additional modelling features in Simulink. The goal of the facilities
provided is to be able to model a distributed computer system within Simulink,
and as a consequence, to be able to carry out cosimulation of functionality
implemented in distributed computer systems.
The work is similar in nature to the ARTES project Integrated Control
and Scheduling; however differing in a least two important aspects:
- a main focus in AIDA is on distributed systems
- another strong focus is on architectural design, including control,
software and hardware, with associated methods.
We believe that the work on the prototype is essential for the further
development of the modelling framework. Early versions of the prototype
have
been demonstrated for industry (see below) and a great deal of interest
has been shown. Applications and publications of this work is under way.
The work in AIDA is carried out in close cooperation with the ARTES
projects FINE and PICADOR. The idea is to have these projects provide
additional analysis facilitites that can be used in the toolset. There
is also a close relation to the MARCH project with respect to architectural
modelling.
In terms of architectural analysis, there is also a strong link to
the NUTEK funded DICOSMOS project.
2) A list of publications from the project.

3) A statement from the associated industries on
a) the students role in development
of and industrial application or product.
b) the associated industries role
in the project and in the education.
During the year a number of industrial contacts (to spread information,
get feedback, investigate potential case studies etc.) have been taken,
including
- formation of the an industrial reference group for AIDA and PICADOR
The following companies are participants: Combitech,
Adtranz, Arcticus systems. Volvo components (Volvo CE)
In addition, Scania remains in the reference group.
- a meeting with Combitech, DAMEK, Dec. 15, 2000
Due to personel exchange at Combitech, the purpose
was to try to identify a way to continue the collaboration.
Combitech are interested, but currently will only
participate in the reference group.
- a meeting with Adtranz. including representatives from DaimlerChrysler
Research on Nov. 28, 2000.
A great deal of interest was shown. There is a potential
for more concrete cooperation here.
- industrial mobility to Saab Automobile. Ola Redell and Jad Elkhoury
visited Saab during one week to discuss cooperation, and learn about
their system development, architectural design etc.
Best regards
