The Possible and the Necessary for Multiple Criteria Group Decision

摘要

We introduce the principle of robust ordinal regression to group decision. We consider the main multiple criteria decision methods to which robust ordinal regression has been applied, i.e., UTA~(GMS) and GRIP methods, dealing with choice and ranking problems, UTADIS~(GMS), dealing with sorting (ordinal classification) problems, and ELECTRE~(GMS), being an outranking method applying robust ordinal regression to well known ELECTRE methods. In this way, we obtain corresponding methods for group decision: UTA~(GMS)-GROUP, UTADIS~GMS-GROUP and ELECTRE~(GMS)-GROUP.
