Control in Manufacturing - INCOM’98
9th
IFAC Symposium — Nancy/Metz, France, 24 - 26 June, 1998
The main
objective of the INCOM’98 Symposium was to bring together researchers and
practitioners belonging to the international scientific and industrial communities
in the field of the automation of the Production Systems, in order to underline
the new contributions of the Information of Control-Command towards the progress
of Industrial Engineering. This symposium was composed of plenary sessions
and panel discussions allowing discussions on the 6 selected topics, parallel
sessions and posters, to outline the most significant advances. This symposium
wanted to be a place of exchanges and privileged debates in order to prepare
the scientific and industrial challenges of automation of the companies of
the next century.
The 6
major topics of the symposium were covered in a homogeneous way in the plenary
sessions as well as in the parallel and poster sessions. The plenary sessions
played particularly well their role of opening subjects for discussion since
they were followed by audiences varying from 60 to 150 participants. The
parallel sessions provided room for presentations of good scientific quality
on each of the 6 topics. Only the poster sessions did not have the audience
which this type of presentation deserves.
The main
objective of the INCOM ‘98 symposium was achieved with a good participation
from the academic and non academic communities which was 77% and 23% respectively.
With
45% of the participants from abroad, the international character of the
symposium was significant. 58% of the contributions came from 28 countries
of 5 continents.
THE
6 TOPICS OF INCOM’98
ADVANCED
AUTOMATION ENGINEERING
The increasing
software and hardware capabilities of Information Control Technologies have
contributed to Process System Automation Engineering as well as to Manufacturing
System Automation Engineering for several decades; each one with its own approach.
First, this topic aims at outlining that the relevant concepts, theories,
models, methods, methodologies, languages and tools have to be unified to
cover a whole Automation Engineering life-cycle in order to take into account
the hybrid nature of an Industrial Control System. This topic also aims at
focusing on advances in the field of Automation Engineering such as control-software
components verification, automation object-oriented modeling, distributed
control architectures, embedded control systems, synchronous approaches, and
so on. Finally, This topic aims at investigating new paradigms as well as
new application areas for Automation Engineering at large.
EMERGING
TECHNOLOGY FOR ADVANCED MANUFACTURING
One of the
major consequences of Factory Automation during the last decades has been
the emergence of new technologies based on the integration of software-based
technologies within hardware-based ones to increase the productivity of the
whole automated production system. First, this topic aims at outlining that
the relevant existing engineering processes have to be integrated in a concurrent
approach in order to engineer or reengineer an advanced industrial system.
This topic also aims at focusing on advances in the field of Production System
Automation such as the product system, the process system, the actuation &
measurement system, the supervision system, the maintenance system, the management
system, etc. Finally, this topic aims at investigating new technologies as
well as new application areas for Industrial Automation at large.
INFORMATION
TECHNOLOGY FOR INTEGRATION IN MANUFACTURING
Despite
the advances in Information Technology, Enterprise Integration is still a
challenge at the company level (intra-enterprise integration) or among enterprises
(inter-enterprise integration) as well as for the extended enterprise for
creating a synergy between people, technology and processes to satisfy customers’
requirements. First, this topic aims at outlining Integration as an interdisciplinary
problem relying on organizational, technological, economic and human issues.
This topic also aims at focusing on enterprise modeling, organizational aspects,
resource aspects, process description languages, process management, workflow
management, information systems, information infrastructures, electronic data
exchange, product and process data modeling, integration platforms and model
enactment issues for integrated production problems. Finally, this topic aims
at investigating new methodological and technological ways as well as new
application areas for Integration in Manufacturing at large.
INTELLIGENT
MANUFACTURING AND PROCESS SYSTEM ENGINEERING
Industrial
System Engineering is undergoing a major paradigm shift as the hierarchical
model which has contributed to the development of Automation Engineering,
Factory Automation and Enterprise Integration during the second half of the
20th century and which now seems not fully suitable for supporting Global
Manufacturing towards the 21st century. First, this topic aims at outlining
that Enterprise Integration has to move to distributed architectures in order
to support the dynamic relationships required by the next generation of Manufacturing
and Process Systems. This topic also aims at focusing on a holonic approach,
functional engineering, agent-based architectures, intelligent field factory,
virtual manufacturing environment, distributed autonomous systems, etc. Finally,
this topic aims at investigating new ways of engineering as well as new application
areas for distributing "Somewhat of Intelligence" in Manufacturing at large.
MANAGEMENT
OF ADVANCED MANUFACTURING TECHNOLOGY
However,
Human-centered Industrial Engineering is probably the major challenge that
both the industrial and academic communities will have to take up both in
Research & Development and Education & Training to meet the Intelligent
Integration vision for rebuilding the Enterprise of the next century. First,
this topic aims at outlining the impact of sophisticated Information Control
Technologies, not only on the Product or the Technical System, but also on
the Human System. This topic also aims at focusing on advances in socio-technical
management of technology such as innovation, learning by doing, decision making,
cognition, etc. Finally, this topic aims at investigating new ways of thinking
as well as new application areas for managing Advanced Manufacturing Technology
at large.
INDUSTRIAL
SAFETY, DEPENDABILITY AND QUALITY
In this
way, Human-centered Industrial Engineering has to deal with the problem of
finding a balance between the growing complexity of Industrial Systems and
the control of the risks incurred by their overall environment. First, this
topic aims at outlining that breaking off the partitioning of the multi-disciplinary
points of view on the Safety, Reliability and the Quality of a Complex System
with a global and integrated approach is the key for industry to successfully
master the failures of Control-Systems based on sophisticated Information
Technologies. This topic also aims at focusing on advances in design, instrumentation,
diagnosis, operation, organization, standardization, certification, etc.,
related to safety systems. Finally, this topic aims at investigating new ways
of engineering as well as new application areas for integrating Safety, Dependability
and Quality in Industry at large.
INCOM’98
was built around these 6 topics related to advances in Industrial Engineering,
from the more classic fields to the emergent trends about information control
in manufacturing.
Exchanges
between industrial R&D and academic R&D outlined a significant gap
between the two communities. This difference is not only scientific but
also in the objectives of research; for example, it appeared, at plenary
sessions, that a scientific corpus could be well established and admitted
in an academic community but could not really be implemented in the industrial
world. It is the control of research which is in question; the practical
validation of work is often a simulation or such a rough approximation of
industrial reality that the results have little chance to be applied. Research
is often in "open-loop" with respect to the industrial world or in "closed-loop"
within a community which permanently self-validates its assumptions and
results of work. Thus, certain researchers of INCOM’ 98 felt embarrassed
by the fact that the subjects as discussed in parallel sessions did not
enable them to follow all work of their community; they did not understand
that this organisation made it possible for them to open their minds to
other scientists and disciplines. In conclusion, the Cybernetic Model should
be applied to the process of research itself.
CONCLUSIONS
AND RECOMMENDATIONS
It is the
methodical construction of the program of INCOM’98 during 3 years which led
to its scientific success. An important international committee brought together
representatives of the academic and industrial communities on a high scientific
level (academics, researchers, doctor-engineers, members of international
programs of R&D, ...). The program was then built on 3 types of sessions
which gave it a coherent scientific base. Indeed, the plenary and organized
sessions made it possible to guarantee a priori a logic set of themes with
the whole symposium objective (advances in industrial engineering) which explains
the strong industrial implication (the industrialists knew in advance what
to expect from this conference).

Real
Time Programming
23rd
IFAC/IFIP Workshop — Shantou, Guangdong Province, China, 23 - 25 June, 1998
Owing to
the proliferation of embedded computerised control systems in all areas of
our lives, the amount of software installed in these systems is presently
doubling within just 18 months. This simple figure suffices to characterise
the significance of the area of real time programming and real time software
engineering. Owing to the corresponding demands for the functionality and
dependability of complex real time systems, our intellectual and engineering
abilities are being challenged to come up with practical solutions to the
problems faced in their design and development.
Covering all aspects of software engineering for real time and embedded computer
control systems, the IFAC/IFIP Workshops on Real Time Programming have addressed
this important field for already more than 30 years. This year the meeting
was held in Shantou, Guangdong Province, P.R. China. It was organised on behalf
of the Chinese Association of Automation by Shantou University, and held on
its premises. The workshop was generously supported, both ideally and financially,
by the Shantou City Municipal Government, the Chaozhou City Municipal Government,
the Advanced Education Committee of Guangdong Province, Sun Microsystems and
by Shantou University.
The participants came from 13 countries. Their number (80) was larger than
in former years, but could easily be handled with the excellent conference
facilities of Shantou University. Fifty participants came from the Chinese
mainland showing the great interest of Chinese scientists to participate in
an international conference.
The 48 submissions coming from Europe, North America and the Far East were
reviewed by at least three referees each, leading to the selection for presentation
of 25 regular papers and 10 short papers. Thirty of these papers were from
academia, 1 from industry-academia, and 4 from government research agencies.
It is worth mentioning that 7 papers were the result of international co-operation,
and that there were not any no-show papers.
The six regular sessions addressed the subject areas real time communication
and formal specification, operating systems and their analysis, real time
scheduling, real time programming, embedded systems, and neural networks in
real time systems. Two poster sessions were held in the evening of the opening
day for the presentation of the short papers.
Three world-class Keynote Speakers reported on research topics they are presently
pursuing:
- Prof.
Alan Shaw, University of Washington, U.S.A., gave an invited talk on "Real-Time
Issues in Air Traffic Management (and Related) Systems",
- Prof.
Wei Zhao, Texas A&M University, U.S.A., and City University of Hong
Kong, presented a keynote speech on "Real-Time Communications in Computer
Networks", and
- Dr.
C. C. Lim, University of Adelaide, Australia, gave a talk on "Real-Time
Scheduling Theory in Real-Time Control Applications".
The workshop
commenced with an opening ceremony, in which Prof. Liang, Vice-President of
Shantou University, Prof. Huang, Chairman of Shantou University, Prof. Hong,
Vice-President of Shantou City, Prof. Dai, President of the Chinese Association
of Automation, and Prof. Halang, Chairman of the IFAC Technical Committee
on Real Time Software Engineering, addressed the participants with welcoming
speeches. In the evening of the Workshop’s first day the participants were
hosted to a banquet in Shantou University. At the evening of the second day
the participants went by bus to the Hotel of Shantou City, where they were
received to a banquet by Prof. Jiang, Vice-Chairman of Shantou City, and Prof.
Hong, Vice-President of Shantou City. The day ended with a boat tour around
Shantou harbour. The Workshop’s scientific programme closed in the late morning
of the third day. In the offical closing ceremony, the participants were addressed
by Prof. Liang, Prof. Dai and Prof. Halang.

Time Delay Systems
IFAC
Workshop — Grenoble, France, July 6-7, 1998
This first
Workshop in the rapidly growing field of time delay systems was organized
by the Laboratoire d’Automatique de Grenoble, ENSIEG, INPG-CNRS, France. This
Workshop was sponsored by the TC Linear Systems. The 50 participants had the
possibility to listen to 4 plenary sessions, 2 invitated sessions as well
as 30 contributed papers selected from 40 submitted papers coming from 17
countries. The first Plenary session on "Systems over Rings: Geometric Theory
and Applications" was presented by G. Conte (Italy). The second one, on "Algebraic
Tools for the Control and Stabilization of Time Delay Systems" was given by
J.-J. Loiseau (France). C.E. De Souza (Brazil) pointed out main aspects on
the "Robust Stability and Control of State-Delayed Systems". The last Plenary
session concerning "Finite Spectrum Property and Predictors" was presented
by A.W. Olbrot (U.S.A.). The technical papers, arranged in 11 sessions, covered
the field of linear time delay systems, including algebraic and structural
properties, stability analysis, stabilization, Hinf control, robust stabilization
and some applications. This Workshop provided an opportunity for fruitful
scientific exchanges in a very pleasant atmosphere, including interesting
discussions during the gala dinner. Because of the growing interest in the
subject, it was decided to organize the next event on this topic in the year
2000.

5th IFAC
Workshop — Cancun, Mexico, 15-17 April, 1998This Workshop moved to the American
continent for the first time through the support of Professor Fabian Garcia
Nocetti (IIMAS, UNAM, Mexico City) and the Mexican National Member Organisation.
The Workshop, which was held at Krystal Hotel, Cancun, Mexico, was the fifth
in the series; previous Workshops have been held at Bangor-UK, September 1991,
Seoul-Korea, August/September 1992, Ostend-Belgium, May/June 1995 and last
year in Vilamoura, Portugal.
The objective
of the Workshop was to discuss and present new research and application
results in emerging new developments in software and hardware for real-time
control, as well as to bring together engineers and computer scientists
from both the academic and the industrial world. While these meetings support
a variety of interests with strong real-time industrial relevance, software
tools and methods and the use of computational intelligence (neural networks,
fuzzy logic) formed a core of the contributions this time in Cancun.
Following
the Portugal, 1997 example for this IFAC Workshop series, the International
Program Committee required full draft papers for review and also admitted
"Late Breaking Extended Abstracts" to the Workshop. These abstracts consisted
of short 2 page papers which described very recent research results. The
IPC was very pleased with the high quality of the original 60 contributions
received.
Two well-known
international experts in the field were invited by the IPC to present plenary
lectures. They were:
- Professor
Rolf Isermann (Darmstadt University of Technology, Germany): Hardware-in-the-loop
simulation for the design and testing of control systems;
- Professor
Bernard Widrow (Stanford University, USA): Adaptive inverse control based
on non-linear adaptive filtering.
Both Keynote
Lectures attracted much interest and debate and, indeed, both Lecturers were
active in discussions throughout the meeting.
Professor
Graca Ruano organised a Special Session on Parallel and Distributed Algorithms
for Real-Time Signal Processing and Control, arising out of a successful
EU/Latin America programme.
In all,
2 plenary lectures and 46 regular & "late breaking" papers from 20 countries,
were presented in 18 technical sessions during the three days of the Workshop.
Professor Fabian Garcia Nocetti (UNAM, Mexico City) chaired the NOC and
he and his team deserve great credit for the excellent Workshop organisation.
Sessions ran smoothly and were well attended and an excellent rapport between
delegates was promoted by warm hospitality from our Mexican hosts and social
events which captured the spirit and culture of Mexico. For example, delegates
were delighted to be led by a Mexican mariachi band for entertainment at
a Gala Dinner at a local restaurant.
During
the Workshop, the IPC reviewed papers presented at the meeting for possible
publication in Automatica, Control Engineering Practice and IFAC Affiliated
Journals. The AARTC Technical Committtee (Chair, Professor Wook Hyun Kwon)
also held a useful meeting, where, amongst other things, a proposal to stage
AARTC 2000 in Valencia, Spain was supported, and a Best Paper Award was
established for subsequent Workshops through a donation by Professor Kwon.

official opening and the plenary session dedicated to the recent trends in
research and to the EU 5th Framework Programme presentation, the workshop
continued with the topic-specific parallel sessions in the first two
days.
Participating
research institutions introduced their activities in two sessions while
some companies showed their products during the Workshop.
A special
afternoon session was dedicated to the 2nd II/TAP Workshop on Distance Learning
Conception and Exploitation of the Virtual Laboratory in the Framework of
the "Virtual Campus: Academic and Industrial Vision". Here, valuable and
real experiences in the distance education field were presented from the
United Kingdom, Switzerland, France and Spain.
