In MDAI 2009, we encourage the submission of papers on decision making, optimization, data mining, information fusion, risk analysis and related topics. Applications to decision support systems as well as real world problems such as environmental problems and supply chain management problems are welcome.

MDAI 2009 is the 6th MDAI conference. Previous conferences were celebrated in Barcelona (2004), Tsukuba (2005), Tarragona (2006), Kitakyushu (2007), and Sabadell (2008).

Besides, papers, that according to the evaluation of the referees, are not suitable for the LNAI but that have some merits will be published in a CD-ROM proceedings (with ISBN) and scheduled in the MDAI program.

Some special issues are expected. At this time, a special issue at the J. of Advanced Computational Intelligence and Intel. Informatics has been confirmed.
