In recent decades, the practice of operations research and management science (ORMS) has seen a substantial increase in the scientific community. Since the official establishment of the Operations Research Society of America (ORSA) in 1952, the Operational Research Society (ORS) of the United Kingdom in 1953 and The Institute of Management Sciences (TIMS) in 1953, many important developments have consolidated a research area that today encompasses thousands of researchers. These associations have promoted some classical journals in the field that have become the key instruments to disseminate new research contributions. The Operational Research Quarterly, founded in 1950, later became the Journal of the Operational Research Society (JORS), Operations Research (1952) and Management Science (1954). These and other operations research associations have cooperated together through joint international conferences and associations [13]. First, the creation of the International Federation of Operational Research Societies (IFORS) in 1959 between ORSA, ORS and the French Operational Research Society (SOFRO) constituted a world entity focused on operations research which grew rapidly with the incorporation of operational research societies from a wide range of countries. Today the IFORS includes more than 30,000 individual members from 48 national societies. Another important integration process was the constitution of regional associations that encompassed a whole continent, such as the Association of European Operational Research Societies (EURO) in 1975.
