Special issue: Innovative Decision Systems, extended papers from the 12th EANN/7th IFIP AIAI 2011 Joint Conferences.

In the new era of computational intelligence, the ever-expanding abundance of information storage and processing power enables researchers and users to tackle applications on various scientific domains of Decision Support Systems (DSS). The general focus of this special issue is to provide insights on how computational intelligence methodologies and algorithms can be employed in real world applications, so as to produce information systems capable of solving important and hard decision problems. This special issue on "Innovative Decision Systems" contains extended versions of seven (7) papers selected from the 12th EANN/7th AIAI 2011 Joint Conference. The manuscripts were accepted for publication, after passing through a peer review process by at least two independent academic referees. AIAI and EANN are two well-established annual events, technically sponsored by the Technical Committee 12, Working Group 12.5 (TC12-WG12.5) of the International Federation for Information Processing (IFIP) and the International Neural Network Society (INNS) respectively. The 2011 event was held on September 15-18 2011 in Corfu, Greece. [ABSTRACT FROM AUTHOR]
