EURO 2004 July 4-7, 2004 The Association of European Operational Research Societies (EURO) and the Hellenic Operational Research Society (HELORS) are pleased and honored to invite you to Rhodes to attend and enjoy "EURO 2004". The Island of Rhodes, the largest of the Dodecanece complex, is also known as the isle of Sun. The famous poet Pintar mentions in one of his Odes that it was born of the union of Helios, the sun god, and the nymph Rhoda. The capital of this island, also called Rhodes, is actually three cities on one site - modern, ancient and mediaeval. Its history come back in 700B.C. and along the centuries has been gifted with a lot of monuments and sites worthy to see. The fact that the 20th Conference of EURO has chosen as main topic "OR and the management of electronic services", a modern and very important topic for all researchers and interested companies, may represent an additional reason for you to join us on the beautiful Island of Rhodes. The conference is taking place in a five stars environment, which is only 50 meters from thesea. It is a great opportunity to combine your participation to the conference with holidays in Rhodes. Therefore, we are waiting for you and your whole family, and mostly don’t forget to mark your calendars: July 4-7, 2004, Rhodes, Greece.
