were published, resulting, in particular, from the activity of the Society's working group MODEST (MODelling of Economies and Societies in Transition). The members of the POSRS have also published numerous books, edited volumes, and hundreds of papers in highly respected journals and conference proceedings. For example: J. Błażewicz, K. Ecker, E.

Nowadays, the Society cooperates with several journals exemplified by the Journal of Operations Research and Decisions, Control and Cybernetics, Journal of Automation, Mobile Robotics and Intelligent Systems. Conferences The flagship conference series of the PORSR is the biannual BOS (the Polish acronym for Operational and Systems Research) conferences which gather some 100 - 150 participants, both from Poland and abroad. In addition, the POSRS (PTBOiS) co-organizes and co-sponsors numerous other events, both national and international, together with its closely cooperating institutions. Moreover, the POSRS was a co-organizer of EURO 2016 - 28th European Conference on Operational Research (3-6.07.2016), held in Poznań, at the Poznań University of Technology, one of the leading European centers in decision analysis, optimization, project management, and scheduling. Program and Organizing Committees were chaired by Professor Daniele Vigo from the University of Bologna and Professor Joanna Józefowska from the Poznań University of Technology, respectively. It is also worth noting the role of members of the Organizing Committee and pillars of the Operations Research and Management Science group at the Poznań University of Technology: Professors Jacek Błażewicz,
