Abstract (EN)
The abundance of interactive procedures and the increasing number of real-world applications reflect the wide success met by this approach. Based on different technical concepts, grounded on various conceptions, interactive multicriteria procedures clearly reveal interesting features. However, this diversity make them difficult to encompass in a global view. After briefly introducing the interactive approach in MCDA, a general technical framework which gives new insights for the understanding of existing methods is presented. In the second part of the paper, two conceptions concerning the way of considering the decision making process are introduced. These conceptions give rise to a basic distinction between two main classes of interactive procedures whose respective purposes are quite different.
