In view of the Russian invasion of Ukraine, the GDN 2022 conference was moved online. Initially, it was scheduled to take place in Moscow and be hosted by the National Research University.
The conference will be organized virtually by the GDN section of Informs from June 12 to June 16. The submission deadline is March 30. More information about the conference may be found on the official website: http://gdnconference.org/gdn2022/.
As usual, the conference is organized through a series of streams. One of such streams is devoted to "Preference Modeling for Group Decision and Negotiation". It si chaired by prof. Daniel Morais (Federal University of Pernambuco, Brazil) and Tomasz Wachowicz (University of Economics in Katowice, Poland). Please feel invited to submit to our stream!
Preprint of a new EJOR paper

On the website of the European Journal of Operational Research (IF = 5,334, CiteScore 9,5) a new paper written by professors Tomasz Wachowicz and Ewa Roszkowska is available as a preprint for download. In this paper, we verify the technical and empirical applicability of the holistic approach to preference elicitation in prenegotiations. A series of tests were conducted to analyze if the UTA-based approach is technically capable to generate the scoring systems that accurately reflect the negotiators' preferences and what additional mechanism should be offered to assure that technically promising results are retained also in empirical use of such a preference elicitation mechanism. Finally, an enhanced prenegotiation preference elicitation protocol is proposed, which shows promising performance in experimental verification in the eNego system.

From September 22 to 24, 2021, the 16th international conference on operations research was organized by the Slovenian Operational Research Society. The epidemics situation made the organizers conduct it in a remote form as an online event. The conference schedule is available at the conference website: https://sor.fov.um.si/. In the SOR'21 conference, the representatives of the University of Economics in Katowice and the N.EA team were participating. A regular social event for the SOR conference is also a piano concert performed by prof. Tadeusz Trzaskalik from University of Economics in Katowice.
Two new publications in Entropy

Two new papers were published by the N.EA team recently in the Entropy Journal (IF = 2.524).
The first manuscript is an effect of N.EA collaboration with assistant professors Rafał Mierzwiak and Marcin Nowak from the Poznań University of Technology. The paper entitled "Reducing Cognitive Effort in Scoring Negotiation Space Using the Fuzzy Clustering Model" presents a new prenegotiation support protocol to holistically evaluate the negotiation space and define the scoring systems for negotiation offers evaluation. It uses the notion of automatic calibration of the scoring space for the limiting profiles predefined by the negotiators themselves. This notion is derived from earlier work by Wachowicz T. (2010). Decision Support in Software Supported Negotiations. Journal of Business Economics and Management, 11:4, 576-597. The manuscript can be accessed online in an open access formula under the following link: https://www.mdpi.com/1099-4300/23/6/752.
The second manuscript was written in cooperation with late professor Krzysztof Piasecki and prof. dr Anna Łyczkowska-Hanćkowiak from the WSB Poznań University. It is entitled "Fuzzy Representation of Principal's Preferences in Inspire Negotiation Support System" and presents a theoretical framework for defining the negotiation offer scoring system by a group of agents similar concerning selected characteristics. To construct such a generalized scoring system, a notion of the trapezoidal fuzzy numbers was used. You may access the manuscript under the following link: https://www.mdpi.com/1099-4300/23/8/981.

Yesterday, as online first, the latest paper was published in the ITOR (International Transactions in Operational Research) journal, written by the research team of late Gregory Kersten, Tomasz Wachowicz, and Ewa Roszkowska. It continues the series of studies devoted to behavioral issues in negotiations. In this paper, we analyze how the motivational mix determines the negotiators' accuracy in the prenegotiation preparation, in particular, in building the scoring systems that reflect their preferences well.
