New paper in ITOR

In the online-first access of the journal "International Transactions in Operational Research" (ITOR), a new article by the N.EA. team has just been released. The article serves as an extended report on research conducted by Professor Ewa Roszkowska and Tomasz Wachowicz regarding reducing cognitive burdens on decision-makers in decision-analysis processes and defining preferences to be used in formal decision-support methods. The study explores the possibility of replacing, at times numerous and exhaustive, pairwise comparisons (present, for example, in the well-known AHP method) with simple linguistic declarations on a predefined seven-point scale. The results of the experiments strongly suggest that the approach based on linguistic declarations tends to incur certain errors and heuristics, preventing decision-makers from reflecting their preferences as precisely as in AHP. The main reason for this lies in the central tendency heuristic, which causes decision-makers to be reluctant to use extreme ratings on the scale. The article is directly accessible on the publisher's website through the following link: https://onlinelibrary.wiley.com/doi/10.1111/itor.13339.

The conference "Group Decision and Negotiation," organized in a hybrid format by the University of Tokyo from June 11th to June 15th this year, allowed the entire GDN community to meet in person, traditionally within the university's walls, after a two-year break due to the COVID pandemics. A significant group of scientists and researchers from Poland, including members of the N.EA. team participated in the GDN conference. As part of the thematic stream "Preference modeling and decision support in GDN," which is organized every year by Prof. Danielle Moraise (Federal University of Pernambuco, Recife, Brazil) and Prof. Tomasz Wachowicz (University of Economics in Katowice), three presentations by team members were delivered:
- Tomasz Wachowicz, Ewa Roszkowska, Marzena Filipowicz-Chomko: Using unfolding analysis and MARS approach for generating a scoring system from a group preference information.
- Ewa Roszkowska, Tomasz Wachowicz, Marzena Filipowicz-Chomko: Identifying Decision-Making Style. Do REI-20 and GDMS Measure the Same?
- Tomasz Wachowicz, Marek Czekajski: A group decision-aiding protocol for selecting a post-industrial
cultural tourist product in Czeladź Commune in Poland.

Two years after its online publication, an interesting paper of the N.EA team is now published in the special issue of ITOR (International Transactions in Operational Research), entitled "Mind and Cognition in the Future of Decision Support Systems" and edited by José María Moreno-Jiménez and Luis G Vargas. The manuscript results from the previous research and studies conducted by the N.EA team with the late Gregory Kersten. It is devoted to analyzing the links between the motivational system of negotiators and its impact on how well and accurately they use the decision support tools in their prenegotiation activities related to scoring the negotiation template. The manuscript can be accessed freely under the following link:https://onlinelibrary.wiley.com/doi/10.1111/itor.12995.
