The professional objectives of the international symposium are to provide a forum for international and national exchange of ideas on various aspects of OR and related fields. The 15 thВ International Symposium on Operations Research in Slovenia (SOR вЂ™19) will be held in Bled, Slovenia, September 25-27, 2019. You are invited to submit a business, government, or academic panel, workshop or meeting proposals related to all aspects of use, impact and future trends in the vast field of operations research. In the name of the Program and Organizing Committees Please save the dates for our 2021 symposium, which will be held from 22nd to 24th September 2021.

We hope that the simposium offered many answers to questions linked to topics of the symposium and networking opportunities with colleagues and friends. You can find there also the proceedings of SDI-SOR previous symposia SORвЂ™17, SORвЂ™15, SORвЂ™13, SORвЂ™11, SORвЂ™09, SORвЂ™07, and SORвЂ™05. We are happy to announce that Proceedings of SORвЂ™19, which contains blindly, reviewed papers or abstracts of talks presented at the symposium SORвЂ™19, will be available after October 15, 2019, at the SORвЂ™19 internet page and at the SDI-SOR internet page. Please find some of the conference highlights on the website gallery. We would like to thank to all the authors and co-authors of papers, keynote speakers, the speakers at the Opening and Closing ceremony, chairs of sessions and all other participants and sponsors, because without you, the symposium would not be what it was. The results of a field test in which model solutions were actually applied in practice show how one of the largest German grocery retailers was able to increase its profits across different categories and stores by 9.1% on average compared to a control group by using the approach.ДГјsterhГ¶ft, T., HГјbner, A., Schaal, K.We successfully completed the 15th International Symposium on Operations Research in Slovenia вЂ“ SORвЂ™19, held from 25th to 27th September 2019 in the Congress Centre of Hotel Astoria in Bled, Slovenia.

We also consider different shelf segments in different positions. To do this we include a space-elastic function that impacts the customer demand for an item depending on its allocated shelf space.

Our model determines optimal shelf quantities, an itemвЂ™s optimal shelf segment, as well as optimal replenishment frequencies. To account for these constraints, we propose the first shelf-space model capable of modeling three-dimensional shelf characteristics. Without considering the actual shelf dimensions, results from optimization models cannot be transferred to actual shelves. However, in practice shelf sizes and their shelf segments vary in width, height and depth. Existing optimization models approximate shelf sizes by reducing the shelf to a one-dimensional space. Since space is limited, these two decisions are interdependent. The paper addresses the shelf-space and replenishment problem where a retailer must decide how much shelf space to assign to items and how frequently to replenish retail shelves. We are happy to announce that our article вЂњA practical approach to the shelf-space allocation and replenishment problem with heterogeneously sized shelvesвЂќ was accepted for publication in the European Journal of Operational Research (VHB: A).
