Proceedings of the 20th International Conference on Group Decision and Negotiation
The 20th International Conference on Group Decision and Negotiation (GDN 2020) was scheduled to take place at Ryerson University, Toronto, Canada, from June 7th to 11th, 2020. Because of the COVID 19 pandemic, an unprecedented global health crisis, GDN 2020 was most regretfully cancelled on March 25, 2020. When making the cancellation decision, the Council of the Group Decision and Negotiation (GDN) Section, Institute for Operations Research and the Management Sciences (INFORMS), and GDN 2020 General and Program Chairs placed the safety and wellbeing of our GDN community members and their families as paramount.
The series of the Annual International Conferences on Group Decision and Negotiation has taken place every year since 2000 (with one exception, in 2011). The previous conferences have been held at Glasgow, UK (2000); La Rochelle, France (2001); Perth, Australia (2002); Istanbul, Turkey (2003); Banff, Canada (2004); Vienna, Austria (2005); Karlsruhe, Germany (2006); Mont Tremblant, Canada (2007); Coimbra, Portugal (2008); Toronto, Canada (2009); Delft, The Netherlands (2010); Recife, Brazil (2012); Stockholm, Sweden (2013); Toulouse, France (2014); Warsaw, Poland (2015); Bellingham, USA (2016); Stuttgart, Germany (2017); Nanjing, China (2018); and Loughborough, UK (2019). The 20th International Conference on Group Decision and Negotiation (GDN 2020) was scheduled to be a truly international conference, with submissions from 26 countries located in the Americans, Asia, Africa, and Europe. At the time of conference cancellation, the preparation for GDN 2020 came almost to the final stage. Notwithstanding unprecedented circumstances, we remained committed to the publication of conference proceedings.
GDN 2020 received 74 submissions and the conference proceedings are published in two volumes. The first volume contains the 14 full papers selected in a rigorous blind review process [1]. The current second volume contains 44 full and short papers also selected in a rigorous blind review process.
