Cognitive support methods for multi-criteria expert decision making

In this paper, written for the session on multi-criteria decision analysis of the EURO XV Conference (Barcelona, July 1997), we present different cognitive methods for supporting an expert decision maker in her/his daily decision practice. The first part of the paper deals with the construction of a cognitive artifact of the decision problem. The second part discusses the main methodological components of our approach and the final part introduces some possible approaches as candidates for an ecological validation.
