The Croatian Operational Research Society (CRORS) is the professional non-profit society for the scientific field of Operations Research in Croatia.[1] Its main mission is to promote operational research in Croatia and worldwide for the benefit of science and society.[2] Since 1994, CRORS has been recognized by the International Federation of Operational Research Societies and its subgrouping, the Association of European Operational Research Societies, as the main national society for Operations Research in Croatia,[3] and CRORS actively participates in international promotion of operational research.


The Croatian Operational Research Society was established in 1992. as the only scientific society in Croatia specialized in operational research. Two groups of OR people, one from Zagreb and the other from Split, were active in organizing the OR Conference KOI ‘91 and establishing the CRORS, together with colleagues from Varaždin, Rijeka, Ljubljana and Maribor. In March 1992, The Founding meeting of CRORS was held at the Faculty of economics in Zagreb. The Statutes of CRORS were acquired at that meeting, and the Board of directors with a Supervisory board was elected. The first president was Prof. Luka Neralić from the University of Zagreb, Faculty of Economics Zagreb.


The main board of the society consists of a President, Vice President, Secretary and Treasurer. The society is managed by an Executive Committee consisting of 17 members; the Supervisory Board and Board of Ethics consists of 3 members. All members of the boards are elected by the membership.


As of 2014, the society has 150 members - individuals and institutions from academia, industry and administration.
