Purpose and history
EWGLA is a Working Group devoted to Locational Analysis within EURO. It was born during the first EURO Summer Institute, held at Brussels, July/August 1984, devoted to the subject of Location Theory. The main aim of starting up the Working Group was to provide a network of people working together in the field of Locational Analysis and to keep continuity in the exchanges between the Summer Institute's participants. Since that time the group has experienced important growth, in particular thanks to the Twelfth EURO Summer Institute, again devoted to Location theory, and held at Puerto de La Cruz, Tenerife, Spain, June 1995, organised by laureates of the first ESI, and the EURO Winter Institute on Location and Logistics in Estoril, Portugal in jan-feb 2007, organised by laureates of the 1995 ESI.
The scope and purpose of the group have strongly evolved. Friendship among its members continues however to play an important role.
Topics
The subjects of interest to the group are of many kinds, centering on the optimal choice of locations for one or more objects (usually called facilities), within any framework (the classical settings being discrete, network and planar). Many other fields have direct connections with locational analysis and location theory, either by subject such as transportation and routing, supply chain management, environmental studies, layout and design, data and cluster analysis, or as techniques, like mathematical (linear, integer, non-linear, convex, global, ...) programming, multicriteria analysis, approximation theory, computational geometry, statistics, etc.
EWGLA has become a vehicle of communication between all persons interested in Location and related topics in Operations Research in Europe and abroad. The major goal is to stimulate the exchange of information and collaboration in research and applications, and to promote the ideas and methods developed within the field. Several instruments are used to this end.
Meetings
The group holds yearly meetings organised by one of its members (see details below). Anyone interested in presenting their work, participating in the discussions, or more simply learning and/or consulting about subjects related with locational analysis may join the group and its meetings; their participation will be greatly appreciated. Either theoretical contributions (concepts, methods, etc.), applied research, and the presentation of software, are welcome. Communications, discussions or surveys on new applications, open problems, connections between the field of location theory and related areas are of interest. These meetings have always been an enjoyable and very friendly come together of a relatively small but cosy, enthusiastic and energetic group, stimulated by their common centre of interest. Refereed proceedings of each meeting are usually published, and provided free of charge to the participants.
Communication
Communication within the group is achieved in two main ways: the website and the list-server.
Website
The first contact-point is the EWGLA website (fully available soon). This website is a tool for first contact and/or entry in the field, for researchers working in the field, and last but not least for anyone in need of information about the field of location analysis in view of applications. It is our primary means of promotion, communication and open entry point to anyone interested in the topic of location.
Anyone interested in detailed and/or up to date information around Locational Analysis and EWGLA is advised to check this site. The website first provides a general literature list and access to large bibliographies and information about software; and second gives general information about our group, its meetings and other activities, a member-list, and news related to the group's centres of interest. There bis also a FAQ with technical questions on location, and a list of timely happenings and opportunities.
Listserver
The second and more direct way of communicating between the members was established through the EWGLA list-server. Any message sent to the EWGLA listserver. is distributed to all EWGLA members.
Regularly messages are sent around by the EWGLA Board concerning conferences, new publications and other information related to and/or of interest to the members.
Past activities
EWGLA 17
The XVII Meeting of EWGLA, organized by Mercedes Landete, was held in Elche, Spain, 17-19 September, 2008. For further details see the EWGLA XVII website
EWI 2007 Location and Logistics
EWI2007 has been held from Jan 26 to Feb 11 in Estoril, Portugal, organized by F. Saldanha da Gama.
25 promising young european researchers in the areas of Location and Logistics, selected by their national OR society, have taken part in this two week seminar. They presented their own unpublished work, attended several seminars by well known researchers in the area and participated in workshops and a common research activity. The EWI ended by a participation in the EWGLA meeting. For details see the EWI website.
EWGLA 16
The XVI Meeting of EWGLA, organized by M. Ndiaye and F. Saldanha da Gama, was held at Estoril, Portugal, from February 9 to 11, 2007. For further details see the EWGLA XVI website
Brief report
The XVI Meeting of the Euro Working Group on Locational Analysis (EWGLA XVI) was organized by Francisco Saldanha da Gama (University of Lisbon, Portugal) and Malick Ndiaye (King Fahd University of Petroleum and Minerals, Saudi Arabia) and was held in Estoril, Portugal, from February 9 to 11, 2007.
Estoril is a small town, 20 kilometers away from Lisbon, located on the coast.
Overall, more than 50 participants coming from 11 different countries (including Belgium, France, Germany, Great Britain, Greece, Italy, Portugal, and Spain) took part in the meeting.
Financial support came from the Operational Research Centre at the University of Lisbon, the Estoril & Sintra Convention Bureau, BPN, BPI, IBM Portugal, and EURO, for which we once more express our gratitude.
A total of 31 scientific papers were presented and discussed at the meeting. The time limit for each presentation was set to 30 minutes, including time for discussion. Parallel sessions were avoided in order to focus on the respective presentations and to enhance discussions. The topics presented at the meeting covered the following areas:
• Continuous, network and discrete location problems;
• Competitive location problems;
• p-median problem;
• Ordered median problems;
• Applications of location problems;
Most talks were of high quality. Theoretical as well as practical issues were addressed. Therefore, a lot of interesting and fruitful discussions evolved and various ideas for new research directions were proposed.
Several organizational issues concerning the EWGLA were discussed in the EWGLA-session.
In addition to the scientific program, a conference dinner took place at a restaurant in Sintra. During the dinner the city of Elche, in Spain was proposed for the next EWGLA-meeting in september 2008, to be orgainsed by Mercedes Landete.
