Today (26th May 2022) is the second anniversary of the death of professor Gregory Kersten, an outstanding scientist and founder of electronic negotiation and electronic negotiation systems. Gregory Kersten was a person devoted to his family, work, and science. He helped many young researchers to start their careers and stimulated them to be creative and innovative in their studies. He had remarkable achievements, both scientific and organizational. The latter concentrated on consolidating and promoting a scientific environment working in the field of group decision and negotiation. Was a former president of the GDN Section of INFORMS, editor in chief of Group Decision and Negotiation Journal, and good-spirit and animator of Group Decision and Negotiation conferences organized yearly by the Section. We still miss him in GDN and N.EA.

W dniach 14-28 kwietnia 2022 roku w Politechnice Białostockiej odbyło się spotkanie projektowe zespołu N.EA. Spotkanie poświęcono organizacji nowych eksperymentów badawczych związanych z percepcją narzędzi wspomagania decyzji w negocjacjach. Zespół przeprowadził również prace analityczne nad zbiorem danych z poprzednich eksperymentów i przygotował dwie publikacje naukowe wysłane do czasopism z JCR. Jednym z elementów naukowych był również wykład gościnny dra hab. Tomasza Wachowicza pt. "Elektroniczne wspomaganie decyzji i negocjacji. Metody, narzędzia, eksperymentalna weryfikacja". Równie ważnym wydarzeniem natury naukowo-socjalnej był uroczysty bankiet zorganizowany w klimatycznym białostockim pubie-restauracji Sherlock Holmes, w ramach którego celebrowaliśmy nadanie przez Prezydenta Rzeczypospolitej Polski tytułu naukowego profesora Ewie Roszkowskiej! Gratulujemy!

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.
