This volume contains papers presented at the 6th International Conference on Modeling Decisions for Artificial Intelligence (MDAI 2009), held in Awaji Island, Japan, November 30 – December 2, 2009. This conference followed MDAI 2004 (Barcelona, Catalonia), MDAI 2005 (Tsukuba, Japan), MDAI 2006 (Tarragona, Catalonia), MDAI 2007 (Kitakyushu, Japan), and MDAI 2008 (Sabadell, Catalonia) with proceedings also published in the LNAI series (Vols. 3131, 3558, 3885, 4617, and 5285).
The aim of this conference was to provide a forum for researchers to discuss the theory and tools for modeling decisions, as well as applications that encompass decision-making processes and information-fusion techniques.
The organizers received 61 papers from 15 different countries, from Asia, Europe, and America, 28 of which are published in this volume. Each submission received at least two reviews from the Program Committee and a few external reviewers.
