Vom 18. bis 20. September 1974 trafen sich wiederum über 300 OR-Fachleute und am Operations Research Interessierte zu der inzwischen schon zur Tradition gewordenen Jahrestagung der Deutschen Gesellschaft ftir Operations Research, um Erfahrungen aus­ zutauschen, über Probleme und Methoden zu diskutieren, und um ihren Beitrag zum Fortschritt des Operations Research zu leisten. Man traf sich dieses Mal in der in vielen Hinsichten äußerst reizvollen Stadt Würzburg, die einen zugleich würdevollen als auch'anregenden Rahmen ftir den Gedankenaustausch bot. Die Tatsache, daß Würzburg der Sitz des Physica-Verlags ist, der die DGOR dankens­ werterweise dorthin eingeladen hatte, ist einer der Gründe daftir, daß wir bereits zwei Monate nach Abschluß der Tagung die 35 Vorträge umfassenden Proceedings vorlegen können. Die Autoren dieser Beiträge stammen aus Deutschland und Österreich, und sie sind wie­ derum sowohl in der Praxis als auch in den Hochschulen tätig. Es ist daher wiederum nicht verwunderlich, daß das Spektrum der Beiträge von recht theoretischen Vorträgen bis zu Berichten über praktische Anwendungen längst bekannter OR-Verfahren reicht. Wir verstehen diese Zusammensetzung des Tagungsprogrammes als einen Teil der Einlö­ sung des Versprechens, daß die DGOR die Aktivitäten, sowohl der DGU als auch des AKOR fortzuführen bereit und gewillt ist.
