IFAC (IFIP/IFORS) Symposium on Transportation

Chania, Crete, Greece

June 16 - 18, 1997

The Symposium was organised by the Department of Production and Management Engineering of the Technical University of Crete (Chania, Greece) on behalf of the Technical Chamber of Greece, the Greek NMO of IFAC. The event was sponsored by the IFAC TC on Transportation Systems and co-sponsored by IFIP, IFORS and the IFAC TCs on Air Traffic Control Automation, Automotive Control and Marine Systems. This was the first event to be held in Greece and marked the beginning of a number of forthcoming IFAC Symposia and Workshops that will be organised in this country shortly.

The Symposium was very successful in terms of paper submission and international attendance which certainly reflects the importance of transportation-related research within the automatic control field. A number of 405 extended abstracts were received and reviewed by two IPC members each. The IPC comprised a total of 48 members from 20 different countries. Out of 285 accepted abstracts, 264 full papers were received and were included in the Final Program, organised in a total of 58 sessions. Five parallel streams of sessions (excluding the plenary sessions) were scheduled during the Symposium. A total of 229 papers were actually presented at the Symposium versus 35 no-show papers (13 %). The total attendance to the Symposium was 286 participants from 32 countries, most of them from Greece (45), Italy (41), USA (40), France (22), Germany (21), UK (20), The Netherlands (17) and Israel (10). The share of participants by employer type was 61 % from universities, 17 % from companies, 17 % from research institutes, and 5 % from administrations.

The Symposium covered mainly the systems and control aspects of all transportation modes, with roughly 50 % of the papers related to road traffic, 14 addressing rail systems, 10 % on intermodal and freight, 7 % on public transport, 7 % on marine systems, 6 % on air traffic and 6 % on automated highway systems. Highlights of the Symposium were the three plenary presentations, i.e. ‘Contributions of Traffic Theory Toward Deployment of Intelligent Transportation Systems’ by D. Gazis (Gazis Associates, USA); ‘Automated Highway Systems: The Smart Way to Go’ by R. Horowitz (University of California, Berkeley, USA); and ‘Mechatronics in Ground Transportation - Current Trends and Future Possibilities’ co-authored by W. Kortüm (DLR, Germany), R.M. Goodall (Loughborough University, UK) and J.K. Hedrick (University of California, Berkeley, USA), presented by the first co-author. Moreover a keynote address on ‘The Information Society and Mobility: Telematics Applications in Transport’ was presented by the Director of the European Transport Telematics Office, F. Karamitsos.

According to the opinion of most participants, the Symposium was successful both from the organisational and the technical point of view. Most presentations were of high quality and gave rise to interesting and fruitful discussions within and outside the sessions. Most recent trends and current research areas of traffic and transportation systems were covered in corresponding sessions. The preprints span three volumes and a total of 1500 pages. Besides the hardcopy, a CD containing the three preprint volumes was handed out to all participants.

We would like to thank the IPC and NOC members for their excellent work, our University for manifold support, the IFAC Secretariat and Elsevier Science for their continued support, particularly with respect to publications matters, and, last but not least, all participants that made a highly interesting technical event possible.

Advances in Control Education

4th IFAC Symposium

Istanbul, Turkey, 14 - 16 July, 1997

The 4th Symposium on Advances in Control Education was sponsored by the IFAC TC on Control Education (EDCOM), the TC on Automation in Developing Countries, and co-sponsored by the TC on Social Impact of Automation. It was excellently prepared and organized by the Turkish NMO’s national Organizing Committee chaired by A.T. Dinibütün. The goal of the Symposium as of the three preceding events (Swansea 1988, Boston 1991, Tokyo 1994) was again to provide an international forum for the discussion of recent developments and advances in control education as well as the dissemination of knowledge and experience in alternative methods and approaches in education. Several papers dealt with the latter topics initiating some discussion.

The Symposium was opened by the Rector of Istanbul Technical University, Prof.Dr. Gülsün Saglamer; each day began with one of the following plenary lectures. M. Athans (MIT): ‘How to Teach Robust Multivariable Control System Design’; V. Kucera (Czech Academy of Science): ‘A Bridge between State-Space and Transfer Function Methods’; E. Tulunay (Middle East Technical University, Turkey): ‘Teaching and Research in Industrial Process Control and Instrumentation’. The 14 technical sessions were dedicated, among others, to curricula, new ways of teaching control, laboratory experiments, software tools, continuing education and training. A new invention at the 3rd Symposium in Tokyo was the video competition; this time, again a video tape on a laboratory experiment was awarded at the closing ceremony. 97 delegates from 32 countries participated and the authors of 78 accepted regular papers came from 36 countries; 12 papers could not be presented because their authors were not present. Although some excused themselves, there were others who were no-show authors with no excuse given.

It should again be mentioned that the Symposium was perfectly organized and the social events in and around the fascinating city of Istanbul were exciting. Heartfelt thanks go to A.T. Dinibütün, his colleagues and to all who helped. At the Tokyo Symposium, the Japanese friends dedicated a beautiful ACE banner to the TC on Control Education. At the closing ceremony of ACE’97, this banner was passed to L. Vlacic, representing the Australian NMO that will host the ACE 2000.

Distributed Computer Control Systems (DCCS ’97)

14th IFAC Workshop

Seoul, Korea, July 28 - 30, 1997

This 14th Workshop on Distributed Computer Control Systems was held under the auspices of IFAC’s Technical Committee on Distributed Computer Control Systems and organized jointly by the Engineering Research Center for Advanced Control and Instrumentation (ERC-ACI), Seoul National University and the Korean IFAC NMO, the Institute of Control, Automation and Systems Engineers (ICASE). It was also co-sponsored by the IFAC TC on Large Scale Systems (SML), the IFAC TC on Algorithms and Architectures for Real-Time Control (CCT), the IFAC TC on Real-Time Software Engineering (CCR), the IFAC TC on Man-Machine Systems (SMM), the Korea Science and Engineering Foundation (KOSEF), and the Automation and Systems Research Institute of Seoul National University (ASRI). Professor Ian McLeod chaired the International Program Committee and Professor Wook H. Kwon, Dean of the School of Electrical Engineering, Seoul National University, chaired the National Organizing Committee. The Workshop was held at the campus of Seoul National University in Seoul, the capital city of Korea.

18 members of the International Program Committee and three members of the the National Organizing Committee carefully reviewed the 57 extended abstracts submitted from 21 countries. Even though the topics on distributed computer control systems are very diverse, two major disciplines were considered for the paper selections. The first discipline was to focus on the growing interest in real-time systems and networks including field-bus networks. The other one was to introduce industry application results in the above areas. As a result, 33 regular papers were selected for the presentation at the Workshop. In addition to these regular papers and to make the exchange of ideas more profound, three plenary papers by the well-known scholars, M.G. Rodd, H. Kopetz and K. Ramamritham were invited. Professor Rodd gave a talk regarding real-time issues over a fieldbus, and Professor Kopetz focused on large-scale distributed real-time systems. Professor Ramamritham discussed about the temporal data and their management. These 36 papers were classified into four major categories according to their topics:

The Workshop was held during two and a half days, with continuous seven sessions; real-time systems, modeling for distributed computer control systems, applications in distributed computer control systems (1), fieldbus network for real-time control, real-time network for distributed control, applications in distributed computer control systems (2), and architecture for distributed control systems. At the Workshop, 29 papers out of 36 were presented by their authors and will be included in the final proceedings, edited by Wook H. Kwon and Ian MacLeod. The International Program Committee recommended ten papers for possible publication in Control Engineering Practice (CEP) and two papers for consideration of publication in Automatica.

During the Workshop, the participants enjoyed some cultural activities. The first evening, a traditional Korean dinner was served together with a Korean traditional performance. The participants were also invited to a technical visit to the campus of Seoul National University including the Automation and Systems Research Institute (ASRI), the Engineering Research Center for Advanced Control and Instrumentation (ERB-ACI) and the School of Electrical Engineering. After the technical sessions, the participants had the opportunity to visit Samsung Electronic Company.

Finally it should be mentioned that there were also TC meetings during and immediately after the Workshop. At the TC meetings, many fruitful ideas and comments were discussed for the future of the IFAC TC on Distributed Computer Control Systems (CCD TC) and the coming DCCS workshop.
