A new PCCA method: IDRA

IDRA (Intercriteria Decision Rule Approach), a new MCDA (Multiple Criteria Decision Aid) method which adopts the PCCA (Pairwise Criterion Comparison Approach) methodology, is presented. It is based on two principal hypotheses about the intercriteria information furnished by the decision maker: the mixed utility function, i.e. it is assumed that in the decision process both tradeoff and importance intercriteria information are considered; and bounded consistency, i.e. no constraint is imposed on the consistency of the intercriteria information. © 1997 Elsevier Science B.V.
