This special issue contains selected papers of the XXIX. Hungarian Operations Research Conference that went through the usual refereeing process according to the policy of CEJOR. This national OR conference took place again at Balatonőszöd, between 28 and 30 September, 2011. The primary organizer of this conference was the János Bolyai Mathematical Society, collaborating with the Hungarian Operations Research Society (HORS) and the Hungarian Society for Economic Modeling (HSEM). The chairman of the organizing committee was Tibor Jordán, vice secretary of the János Bolyai Mathematical Society, and the head of the Program Committee was Tamás Szántai. The number of participants was over 110, the scientific program comprehended three plenary talks and 62 contributed presentations in two parallel sessions. The language of the conference was Hungarian. More information can be found at the home pagehttp://www.bolyai.hu/opkut/dokumentumok.html
(in Hungarian).
It is already the sixth special issue of CEJOR devoted to the Hungarian Conference of Operations Research, and we hope that this tradition provides values for the OR community in Central Europe and beyond. The scope of the conference involved several aspects of operations research: a good mixture of theoretical results and successful applications were presented. Sorting out the best papers of the conference, the aim of this special volume is to demonstrate the current strength of the Hungarian operations research community. We have received thirteen submissions for this volume. Each manuscript was reviewed by at least two anonymous reviewers, and after some rounds of peer reviewing, eight papers were accepted. The editors of the special issue thank the referees for their efforts with which they contributed to the quality of this volume.
The composition of the special issue reflects more or less the versatility of the conference subjects. We have two papers mostly on methodological issues: that written by Antal et al. (2013), and the one by Hajba and Horváth (2013). A contribution by Balogh and Békési (2013) is on semi-online bin packing. Some papers are related to economic models. A paper on multicommodity flow problems was written by Bernáth et al. (2013) and a contribution by Dobos et al. (2013) on supply chain . The paper of Kecskeméti and Bilics (2013) is about bus driver duty optimization, while that by Lévai and Bánhelyi (2013) on the application of optimization for the location of chaotic places of a dynamical system. The paper of Pintér and Radványi (2013) is about the application of game theory for economic modeling.
